First, I suggest we stick with “SER-ber-us” because pronouncing it “Ker-ber-us” fills some people’s  heads with images like these. And we can all agree, that is not a good thing. :-)

Last time, I mentioned Bill Craig’s recent public assertion of his Cerberus analogy for the Trinity. Here’s a remix by an Islamic apologist, with snickering commentary by Reformed Christian apologist James White.

I take it White is not a “social” theorist like Craig, but rather a negative mysterian (refusing to assign much intelligible content to the doctrine) – like those Dallas Theological Seminary folks. In that video linked above, he just asserts that Craig doesn’t know what he’s talking about.

This (that he’s a negative mysterian) in confirmed by this follow up video.  (Or at his blog.) In the name of just sticking with what the Bible says, he just Continue reading »

Stephen Prothero, of Boston University, is the rare professor who is to a household name and face. He’s been on all sorts of media, and is an able spokesman for the cause of religious literacy. Preach it!

His latest book, God is Not One, is possibly the best introduction to a variety of religious traditions for the general reader. It’s well-written, informative, humorous, apt at comparing religions, and I would say pretty fair. I recommend it overall. The book is worth it just for his bashing of the soft-headed pluralism that infects so many popular books on religion. (Ch.1)

Less positively, Prothero’s outlook on religion is colored in many ways by the fact that he is an ex-Christian, having been raised as a mainline church. He sports of whole range of attitudes I see as deriving from this, or from this plus our present intellectual scene. Also, it strikes me that his childhood faith he left behind was just that. In any case, he has a nice way of wearing his inclinations on his sleeve. An author should be opinionated.

Here I want to ask: Is Prothero both fair and accurate in how he presents Christian belief? He says:

…the Christianity… of my childhood… was all about the doctrine of the Incarnation, which to me was as mysterious as adult life in general. According to this core Christian teaching, at the fulcrum of world history God took on the form of a helpless baby, born of a frightened young woman and held in the rough hands of a carpenter. “What if God was one of us?” asks the Joan Osborne pop song. Christianity responds, “He was!” (p. 68)

Well, is.

Again, at one level,  Continue reading »

I’ve been reading some stuff about identity and relative identity lately, in the process of writing something on relative identity versions of trinitarianism. This post is to share some good finds.

In his excellent entry “Relative Identity veteran logican and philosopher of language Harry Deutsch says about the best that can be said for relative identity theories – that maybe, arguably, they solve or help to solve various metaphysical problems. See his sections 2 and 4 for these. His section 5 is a penetrating analysis of Geach’s very hard to follow arguments.

Deutsch’s point of view is very different from that held by most philosophers. For this, see chapter 1 of Colin McGinn’s Logical Properties. (NDPR review.) This is more or less  the “orthodox” view that most philosophers hold, atheist or theist, trinitarian or not. I largely agree with it, except for its Platonic aspect. I uphold the logic of identity as McGinn understands it, but do not want to commit to the existence of abstracta like relations. I think the truthmaker of a sentence like “Dubya just is George Bush” is going to be a concrete object, the ex-president himself. In this, I’m in the minority; most philosophers find abstracta indispensible.

Another place one can start is Harold Noonan‘s excellent “Identity” entry. He’s an excellent philosopher, and the piece has many virtues; in particular, see his section 2 on Leibniz’s Law vs. substitutivity principles.

The best thing I’ve ever read on identity and relative identity is Continue reading »

Yet another round from Steve Hays.

This is my last entry in the discussion; I may or may not comment, but no more posts.

Again, this is what I hear from him:

  • Yes, the divine nature is a universal, shared by the Three. But let’s not make any Platonic assumptions about forms/universals being in some other realm than what has them, or being more fundamental.

Indeed, let’s not.

Are the persons parts of the Trinity, for him?

He brings up the Mandelbrot set. This is an abstract object. It doesn’t have parts, but rather members. Is he suggesting that the Trinity is a set, with members rather than parts? That it has infinite members? I don’t know.

Then, a digression about analogy. Of course, my point was: don’t you think God is literally a self? (Not: Is God analogous to a self?)

Perhaps he assumes that all terms that apply to God do so only analogically. Continue reading »

A lesson in epistemic humility from a great master of 20th century literature:

‘You are a slow learner, Winston,’ said O’Brien gently.

‘How can I help it?’ he blubbered. ‘How can I help seeing what is in front of my eyes? Two and two are four.’

‘Sometimes, Winston. Sometimes they are five. Sometimes they are three. Sometimes they are all of them at once. You must try harder. It is not easy to become sane.’

(George Orwell, 1984)

Winston here doesn’t get it. It seems to him that 2 + 2 = 4 – always! And always, because it is necessarily so; it seems to Winston impossible that adding two to two not result in four. He can see that it is with his eyes, and “see” that it must be with his mind. Or, so he thinks.

O’Brien explains that the Magisterium of the Party is to be trusted above one’s own intuitions. If they say it is three, then it is three. And should that say it is five, it would be five. If they say it is 3 and 4 and 5 – then so be it. Sanity involves trusting their judgements over your own; theirs trump yours. You must know your place, citizen. Only an extreme individualist would disagree.

Is it an apparent contradiction (aka positive mystery)? Sure. Winston seems to think this is somehow a problem.

But is it any surprise that the collective wisdom of The Party should surpass that of a puny, recently born creature like yourself? After all, the Party consists of humans like you, many of them smarter than you. Surely it is sheer arrogance to think you’ve magically become wiser than the Party – the Mother who birthed you, provided for all your needs, and taught you everything you know. Honestly, what is the chance of that? We should expect that some things she tells us do no make sense to us. Thus, that the Party asserts apparent contradictions is evidence that she speaks only truth.

Poor Winston – he thinks he’s sane. But, that’s how a lot of insane people think of themselves.

Winston might try to argue that he really loves the Party, and would like to reform it for the better. Insanely, he doesn’t realize that the Party is just as it should (now) be. Big Brother has seen to it, and we all trust him – at least, those of us who are sane. If he wants to change the Party, he will, and it will be the right change at the right time. Winston is a citizen, and the place of a citizen is to serve and obey the Party, which requires trusting her judgements, which are of course His judgements as well. Winston keeps forgetting that. Thank Big Brother that we have O’Briens to gently remind us.

Below the fold, a bit more therapy: Continue reading »

Call me late to the party. As someone who usually has his nose in a book, I didn’t run out to see The Da Vinci Code. From what I knew of the Bible and Christian history, along with reviews of the book and movie, I could tell that it was ludicrous.

Just recently, out of morbid curiosity, since it’s available free online, I watched all three hours of it.

Yes, the stupid, it BURNS! Don’t say I didn’t warn you.

Hanks mumbles and lurches his way through the movie, like an unkempt Dennis Miller on downers. He was much better in… just about anything else he’s done.

The movie alternates between competent chase scenes, talky sleep-inducing scenes, and scenery chewing by evil, murderous, self-hating, conniving, comic book Catholic villains.

It’s directed by Opie, no less. And he seemed like such a nice kid!

At the end of the movie, the two main characters are reflecting on Jesus, in light of the cockamamie yarn they’ve just lived through. Saith, Hanks’s character: Continue reading »

Over at Parchment and Pen Michael Patton has posted a chapter on the Trinty, part of a forthcoming book called The Discipleship Book, intended to instruct new Christians.

Dear new Christians – beware. Patton is sincere, but misinformed. He thinks the Bible obviously teaches what he’s asserting, and reasons that any prior Bible-loving Christians must’ve thought likewise.

But having studied a vast amount of historical writings by Christians, I can assure you that this is demonstrably not so, even if we stick to “mainstream” Christians (so ignoring, e.g. “Arians”, Marcionites, etc.) I take no pleasure in pointing this out, and I wish it were as simple as Patton says. But facts are facts.

I’ve discussed his sort of take on the Trinty before. It is not, as Patton says in a comment, “what the Bible teaches and Christians for 2000 years have believed.” It is what (some? many?) theologians at Dallas Theological Seminary think about the Trinity. How widespread these views are, I’m not sure. But the many evangelical and other theologians riding the “social trinitarian” bandwagon would not agree with what Patton says.

Regarding what Patton holds forth as “the best we can do”, take care lest you fall into inconsistency.

You should know that some of the most brilliant Christian thinkers in the last 100 years have held many different views on just how “the” doctrine should be understood. Unfortunately, these theories are, for the most part, not consistent with one another.

Patton asserts that Continue reading »

Is the Trinity contradictory? In reply to such a charge or query, there’s a standard opening move employed by trinitarians who have some training in logic, be they theologian, philosopher, or apologist. (I’ve seen this by all three sorts.) It goes like this:

“We’re not saying that God is exactly one A and exactly three A’s. That would be a contradiction. We’re saying that God is one A and three B’s. Where’s the contradiction?”

On the face of it, this is a good and reasonable reply to the charge that the doctrine of the Trinity includes or implies a contradiction (and so is false). In general, we must be careful with facile charges of contradiction; often, such claims are easily rebutted.

But it is only an opening move, and it is a shallow one, as I’ll explain. In fact, it leaves you as exposed as our friend with the raised leg here.

Suppose you say that right now there are ten on the field, and also exactly two on the field. By this, you mean ten players and two teams. This is consistent.

How about ten bugs and two players. No problemo.

Now suppose you say that there are now ten players on the field and exactly two human beings? That is not consistent, for each player just is a certain human being.

Thus, the sort of logical point I made at the outset of this post works sometimes, but sometimes it fails. It all depends on what the terms are, and how they are related.

But does this work or not, in the case of the Trinity?

With creedal Trinity claims, as often understood, A = divine being, and B = divine person Continue reading »

Over at Biola’s alumni magazine, Winter 2011 issue, theologian Fred Sanders has a piece in which he argues,

The Trinity is a biblical doctrine, but let’s admit it: There’s something annoying about how hard it is to put your finger on a verse that states the whole doctrine.

The Bible presents the elements of the doctrine in numerous passages, of course: that there is only one God; that the Father is God; that the Son is God; and that the Spirit is God. We can also tell easily enough that the Father, Son and Spirit are really distinct from one another, and are not just three names for one person. If you hold all those clear teachings of Scripture in your mind at one time and think through them together, the doctrine of the Trinity is inevitable. Trinitarianism is a biblical doctrine and all the ingredients are given to us there: Just add thought and you have the classic doctrine. (emphases added)

Hmmm…. I would have thought that the elements of “the” doctrine included that the three are same substance or essence (homoousios). And that the there are co-equal, and co-eternal, uncreated, though the Father timelessly generates the Son, and the Spirit proceeds from him (or if you’re Western/Latin – from both Father and Son). Maybe something about their having one “divine nature” as well. Continue reading »

Over at Aporetic Christianity Paul has a worthy post on a major new tome of systematic theology, which he says whiffs it on the contributions of analytic philosophers of the last 40 years or so.

I posted on this very phenomenon back in 2008.

I agree with all the examples Paul gives of philosophers / analytic theologians whose work should not be ignored by any serious investigator – not because they’re my peeps – but because their work is disciplined, insightful, well motivated, clearly argued. In short, it has things you want if you’re serious about getting to the truth of the matter.

Why do systematic theologians do this?

Maybe there’s no deep answer. Maybe: (1) they’re not familiar with this large genre, (2) philosophy is hard, (3) they can ignore it – a portion of the intended audience won’t notice. They won’t get any letters protesting the ignoring of Plantinga, Craig, van Inwagen, or Leftow.

To those of us who are philosophically literate, in most cases philosophy-ignoring work just isn’t going to answer our questions. It’s not a matter of style, taste, or preference – but of substance. This is hard to convey to people who aren’t so trained. Here’s an analogy. Imagine you’re a Continue reading »

Over at Aporetic Christianity, Paul M. has a long but interesting and perceptive post on the hostility he’s encountered in some Reformed circles towards analytic theology. (See his whole post if you’re wondering what “analytic theology” is.)

A sample:

Not only is philosophy shunned as speculative and troublesome, many Reformed… disparage some of the tools those in this discipline specialize in utilizing. Logic and analytical rigor are shunned and not trusted. …Theologians and philosophers each do their own thing, neither mining the work of the other. Theologians find the philosophers speculative and often unorthodox. Philosophers find the theologians unclear, dogmatic (in a negative sense), and holding to beliefs based on faulty reasoning and supported by poor argumentation. This state of affairs is odd considering how many theologians of the past made use of continental philosophy.

Past and present, I would say. Check out the whole post. It’s mildly depressing, but to be expected – humans, and academics, are territorial creatures. If only Bugs could mediate this feud – we could all “bow to the gent across the hall”.

What if? (What if 1+1 were 2?)

By “posts”, of course, we mean “posts or comments on posts”.

Read it, live it. Patton is very insightful there.

I speak as one sinner to others.

There’s something about human nature… if we’re convinced that we’re right about some important subject-matter, we start to think we’re entitled to pour scorn and contempt on those without this supposed insight. (This happens especially in matters of politics and religion.) But, we are not so entitled. The fact remains that God loves those people, and expects us to. And we would not like to be treated that way.

What way? Just take notice when others start to get heated up over your comments. It could be that you’ve touched a nerve, i.e. raised a devastating criticism. It could be that they’re spoiled, immature, and over-sensitive. Or, it could be that you’re rude. Judge yourself, lest you be called to account for your words. Usually, we know and take pleasure in online bomb-throwing/groin-kicking/eye-poking. Other times, we’re just operating with less stringent standards, like we’d used with friends via email, or face to face. But whether the damage is intentional or not, it’s damage, and the behavior is thus too rough.

baptism of JesusAs I mentioned some time ago, the ESV Study Bible has a really bad entry on the Trinity, part of its appendix, “Biblical Doctrine: An Overview”. Today, I note that it repeats something I’ve often seen asserted elsewhere.

Perhaps the clearest picture of this distinction and union [of the Trinity] is Jesus’ baptism, where the Son is anointed for his public ministry by the Spirit, descending as a dove, with the Father declaring from heaven, “This is my beloved Son, with whom I am well pleased” (Matt. 3:13-17) All three persons of the Trinity are present, and each one is doing something different. (p. 2514a, emphases added)

This is an example of the sheer laziness and sloppy reasoning that so mars contemporary theology. Think about it - how exactly is the unity of the Trinity displayed here – either their oneness of an individual essence (godhead, divine nature) or the sharing of a universal property of deity? Where exactly do we see portrayed here the absolute equality of the three, or the “full divinity” of the Son and Spirit.

Would anything in this episode cause trouble for, say, an “Arian”? Nope. Tritheists? No – they should be OK with coordinated actions by the deities. Consider those unitarians who think the Holy Spirit is a force or divine action, not a person in his own right. They won’t have any problem with this “descending as a dove” – which of course needn’t mean that a literal dove (or something that looks just like a dove) dropped from the sky. Finally, consider modalists, who think that each person of the Trinity is really a personality of the one divine person, or a way that person acts. They’ll just say that this omnipotent, divine person can easily pull off these three actions simultaneously: getting baptized as a man, speaking from heaven, and coming down from heaven to empower the man.

The one sort of Christian theology that would trip on this, would be a strictly serial modalism – which holds that God acts, in sequence, as Father, Son, and Spirit, but only one at a time. But who holds this? (Apparently, not even these guys – see #56.)

In sum, this episode, spiritually inspiring and important to christology though it is, is nearly worthless when it comes to arguing for or just finding evidence for any particular understanding of the Trinity. Theologians should be more nervous about just repeating these tropes. A narrative which is compatible with almost any view of the Trinity neither implies, asserts, assumes, nor even illustrates “the” catholic/orthodox/historical mainstream view of the Trinity.

A trinitarian facepalm for this, from  a Bob Jones University Press grade school textbook (HT: Digg.)

Not having seen the book, I can’t be sure what is going on here. Here are some options:

  1. The writer is terribly uninformed.
  2. The writer is feigning ignorance in a misguided attempt to instill delight and wonder into science.
  3. The writers is feigning ignorance in an attempt to multiply “mysteries”. If there are a lot of “mysteries” (realities we don’t understand) in nature, then any theological mysteries will be unproblematic. Call this “innocence by association” apologetics.
  4. The writer is ham-handedly trying to make a (controversial) Kantian point about science – that it only reveals how things appear and not how they really are.

I’d like to believe that 1 is unlikely. It could be that all of 2-4 are going on here. Either way, this is clearly educational malpractice, especially the “All anyone knows is that…” part.

Anyone out there have the actual book?

Three World Vision employees are fired because according to World Vision they don’t believe in that Jesus is “fully God” or that he’s a member of the Trinity.

But inquiring minds want to know: what did they believe, what statement or statements of faith did they sign, and are the beliefs therein necessary and sufficient for being a real Christian? This time, we’re digging a little deeper.

Their website saith,

World Vision U.S. hires only those who agree and accept to its Statement of Faith and/or the Apostles’ Creed. (source)

Interesting! Note the “and/or” – employees must affirm either one or both. As we’ve noted before here at trinities, nothing in the so-called Apostles’ Creed requires belief in either the “full deity” of Christ (whatever that may mean) or any sort of trinitarian theory. Continue reading »

The latest Christianity Today magazine features an article entitle “Faith-Based Fracas”, by free-lance reporter Bobby Ross Jr. The main interest of the piece is whether or not it will remain legal for religious organizations to hire and fire on the basis of religious beliefs.

For the record: I support that right.

But the piece is occasioned by a current lawsuit against evangelical charity World Vision brought by three recently fired employees.

It strikes me that there are human and theological angles to this story which have yet to be told.

Here are the relevant bits from Ross’s story in CT:

Both [Sylvia Spencer and Vicki Hulse] signed statements affirming their Christian faith and devoted a decade to World Vision… But in November 2006, they and colleague Ted Youngerberg were fired. Their offense, as determined by a corporate investigation: The three did not believe that Jesus Christ is fully God and a member of the Trinity. (Bobby Ross Jr., “Faith-Based Fracas”, Christianity Today, June 2010, 17-21, p. 17, emphases added)

No doubt the reporter here was hindered by the fact that a lawsuit is underway. But the story has many obvious, yawning gaps: Continue reading »

In the 6th and closing round, Burke argues from reason, scripture, and history.

From reason: The Trinity doctrine, argues Burke, is inconsistent with itself. The “Athanasian” creed presents us with three, each of whom is a Lord, and yet insists that there is only one Lord. As some philosophers have pointed out, it is self-evident that if every F is a G, then there can’t be fewer Gs than Fs. So if every divine person is a god, then there can’t be fewer gods than divine persons. (Burke leaves out this: Why say that this creed presents us with three? Because each one differs from the others, having at least one feature the others lack.)

Since the Trinitarian Jesus is believed to be God, everything in Scripture which applies to God must necessarily apply to him.

Right. If the “two” are really one and the same, whatever is true of one must be true of “the other”. That is, nothing can differ from itself at any given time. Bowman does seem to identify Jesus and God, even while he thinks some things are true of one but not of the other. Point, Burke.

But note that many trinitarians to not Continue reading »

Burke’s fifth round opens some interesting cans of worms.

First, he reiterates that the Bible doesn’t explicitly talk of any triple-personed god, but instead calls the God of the Jews the Father. His Son is Jesus, and they stand in a hierarchy as two persons – the Son “under” the Father – over the realm of angels. He says that “Scripture never includes the Holy Spirit in this hierarchy”, but this begs the question – Bowman’s fifth round focused on passages which he thinks puts the Spirit at the top of the hierarchy alongside Father and Son. Again, I complain about the format of the debate, which forces the debaters to talk past one another.

Second, he cites numerous passages to show that his unitarian take on the Trinity is consonant with apostolic teaching – with their language but also with their concepts, to throw the burden on the trinitarian. About the triadic passages Bowman focuses on, he says only this: “all three were recognised as sources of apostolic authority… It is therefore natural that they appear together in ways which reflect this relationship…” Sources? Like, authorities (selves possessing authority)? I think this needs more spelling out, to make it clearly consistent with Burke’s other views, and to show that it is well-motivated. I read something interesting on this recently. :-)

Can of worms #1: early catholic theology. The most famous of 2nd c. catholic theologians were subordinationists – they held that Jesus was “generated” by the Father through a mysterious act of will prior to the creation of the cosmos. Although they thought of this as the expression of God’s internal and eternal “word” or thought, this is incompatible with later orthodoxy, because the Son isn’t eternal, and is arguably not “fully divine” – as he exists because of something else – God. At times, they even call the Son “a second god”. Burke observes:

None of these early church fathers were Biblical Unitarians – but they weren’t Trinitarians either… even as late as the 4th c…. Christians were hopelessly confused… [even then] the Trinity was still not a fully established doctrine. …Rob is vague about the point at which he believes the church embraced true Trinitarianism, but I receive a general sense that he perceives an implicit Trinitarian Christology within the NT which quickly gave rise to fully-fledged Trinitarianism. …But the history of Trinitarianism… reveals an excruciating mess of debate, controversy, and confusion… How can Trinitarianism be the doctrine once preached by the apostles…? …It is contrary to reason, antagonistic to Scripture, and undermined by the record of history.

So Burke’s point is that trinitarianism can’t have been part of the apostolic message. How does Bowman respond to this blast? Tune in next time, in which I discuss his long response in a comment, and bring up some other relevant historical information.

Can of worms #2: Continue reading »

By theology blogger C. Michael Patton, upon watching the grand finale to the Lost show:

I was duped. If you are honest with yourself, you will admit that you were too. Duped in what way? Duped into believing that the writers knew what they were doing. Duped into thinking that they were less confused than we were. …Although every viewer was completely confused for six years, this did not matter. The confusion only added to the intrigue. We all trusted that the series finale would give us all the answers. We trusted that they knew what they were doing. …Escalation after escalation only handed us more hope. Confusion became our friend as we would discuss so many questions…

We were all lost and we loved it.

We worked under the valid assumption that all of these questions had answers. Of course, this does not mean that we will like the answers, but it was the risk we were willing to take. …We just wanted answers. That is why we watched the show. And we were trusting enough to wait six years to be satisfied.

But such was not the case. At the conclusion of last night’s episode the horrible reality surfaced. That which we all fear in places we don’t like to go became a reality: The writers did not know the answers either.

Oh, and don’t you try to spin this. Don’t you dare. …The arc we thought was there was an illusion. This series took a risk. It was only as good as the resolution and there was none. The writers did not know what they were doing. Hence concluded the greatest hoax in American television history. Hence the realization that the writers of LOST were just as lost as all of us. (emphases added)

By all means, read the whole thing (and the torrent of comments).

Beyond its eloquence, I enjoyed this for three reasons. First, I’ve been observing this disease in my wife, a Lostee. (Luckily, she wasn’t in for a whole six years, thanks to Netflix.) Already heard her version of the rant. Second, I get to gloat, as I steered clear of this series (sounded like too much work). Third, this rant bears remarkable similarities to rants I’ve indulged in after buying and trying to read an over-priced, poorly written book by a much vaunted theologian who is supposed to be an expert on the Trinity. Those rants sometimes involve some mild form of book abuse. Hopefully, Patton didn’t kick his TV, or attempt to throw it.

I still mean to comment on Bowman’s 5th round, but my inner logic nerd was drawn in by some action from round 5 here, comment 19:

[Burke:] “This week I hope Rob will show Biblical evidence for the essential relationship formulae of Trinitarianism:
1. Father = ‘God’, Son = ‘God’ and Holy Spirit = ‘God’
2. ‘God’ = Father + Son + Holy Spirit  . . .

[Bowman] I have already responded to this argument of yours. Your demand that I must prove these two statements “independent of each other” is an absurd demand calculated to place an unreasonable burden on me that you know cannot be met.

As you know, Dave, if statement #1 is true, and if there is only one God (one single eternal divine being), then statement #2 follows. However, you and I already agree that there is only one eternal divine being. Therefore, I do not need to argue for this premise of the doctrine of the Trinity.

Gentlemen, forgive me, but this is confused. We must clarify the meaning of “=” here. I believe that Bowman means  numerical identity in 1. (I’m not sure – I think  his position forces him to be unclear about this – but let that pass.) Let us, then, add the extra premise Bowman mentions (as being held in common). We then get this:

f=g & s=g & h=g

(x)(y) (Dx -> (Dy -> x=y))   [For any x and any y, x is divine only if, if y is divine, then it just is x.]

The first premise is trouble, because it implies f=s=h.

But what to make of “‘God’ = Father + Son + Holy Spirit”. What does the “+” signify? One may (and some will) think of it as the combination of parts, or some kind of conjunction of different things. But this would shift the meaning of “=”. Numerical identity is a one-to-one (actually, always a reflexive) relation – never one-to-many. So if the right hand side is read to mean some kind of conjunction, addition, or combination, then the “=” cannot mean identity. It might mean something like “consists of”, “is a whole constituted by”, or something like that. But whatever it means, it does not logically follow from 1 & 2.

But this interpretation makes 2 irrelevant to 1. It may be that Bowman is thinking this:

Df & Ds & Dh    [Father is divine and Son is divine and Spirit is divine. (This "is" of predication, not the "is" of identity.)]

(x)(y) (Dx -> (Dy -> x=y))

From these, there is no reason to think any interpretation of “g = f+s+h” follows. (First we’d have to clarify the meaning of this latter claim, and then we’d have to add one or more premises, until we had a valid and sound argument.)

But this follows: f =s=h. As Homer Simpson would say: D’oh! Homework for interested readers. Why exactly is this something Bowman can’t accept? (There is more than one reason, I think.) Comment at will.

Bowman then retreats to familiar ground:

What you are really trying to do here is to claim that unless I can show some Bible verses in which the word “God” specifically refers to the Father, Son, and Holy Spirit together, my case for the doctrine of the Trinity fails.

But that is a red herring. All we need is a seemingly sound argument, for a conclusion with which Bowman agrees, and which is arguably trinitarian! Instead Bowman brings back his apparently inconsistent set of five claims; we’ve looked at those before. Insofar as they seem inconsistent, the argument will not seem sound.
