Linkage: Did God the Son change in becoming incarnate?

“Classic” (i.e. mainstream catholic, Platonic) Christian theism holds that God is timeless, and so incapable of any change whatever.

And they add: the Word is God, and the Word became flesh.

Sounds like a change, doesn’t it? First, the Word is simply divine, and a moment later, he’s entered into a “hypostatic union” with a “complete human nature.”

Reformed philosophical theologian James Anderson takes a crack at this one. (HT: Triablogue.) I much like his set-up. I’m less keen on the solution. Short answer: it’s a mystery (apparent contradiction). You’ll have to read his post to see why I chose this pic.

On an alleged counterexample to Leibniz’s Law – Part 2 (Dale)

(click for image credit)

In his comment on my previous post, Brandon points out that he doesn’t assert the case described there to be a counterexample. Rather, he was wondering why it isn’t a counterexample; he was probing to see my response.

Fair enough. I’ve left the title of the post as is just for continuity with part 1.

The case Brandon described, was an omniscient God, who is both subject and object of knowledge of himself. God as knower is subject of knowledge but not object. But God as object is what is known, and not the subject of knowledge. So, don’t we here have something which is and isn’t intrinsically some way (being self-knowing) at a time? If so, the principle is false.

On an alleged counterexample to Leibniz’s Law – Part 1

In a recent post I put forward my own preferred version of “Leibniz’s Law,” or more accurately, the Indiscernibility of Identicals. It’s a bit complicated, so as to get around what are some apparent counterexamples to the simpler principle which is commonly held.

Aside for non-philosophers: philosophers are usually after universal principles, truths which hold in all cases, rather than mere non-universal generalizations, i.e. rough rules of thumb which have exceptions. (An example of the latter: Boys love trucks.) Thus, when a philosophers makes a (universal) claim, other philosophers come along and try to show that it is false with “counterexamples” – real, or even merely possible, examples which show the principle to be false (as it doesn’t apply to them). For example, if someone says that all Texans love tacos, a counterexample to this would be a person who is from Texas and doesn’t like them. Just one counterexample is enough to show a universal claim to be false. When provided with a counterexample, of course, one will often refine, as it were, the original claim (e.g. All native Texans love tacos, or All Texans who appreciate Tex-Mex food love tacos) and the game goes on. This is all in the interest of discovering together what is true and what is false. (In my example, of course, those “refinements” would admit of easy counterexamples too.)

So my principle said, to paraphrase, that for any x and y, x just is (=) y, only if they don’t ever intrinsically differ. (I put this in terms of one having a “mode” at a time if and only if the other also has that mode at that time. Others would call these “intrinsic properties.”)

Here our friend, philosopher and blogger Brandon offered a counterexample, Read More »On an alleged counterexample to Leibniz’s Law – Part 1

A formulation of Leibniz’s Law / the Indiscernibility of Identicals

In discussing the Trinity or Incarnation, I often have an exchange which goes like this:

  • someone: Jesus is God.
  • me: You mean, Jesus is God himself?
  • someone: Yeah.
  • me: Don’t you think something is true of Jesus, that isn’t true of God, and vice-versa?
  • someone: Yes. e.g. God sent his Son. Jesus didn’t. God is a Trinity. Jesus is not a Trinity.
  • me: Right. Then in your view, Jesus is not God.
  • someone: But he is.
  • me: So, you think he is, and he ain’t?!
  • someone: [silent puzzlement]

In this post, I want to explain the part in italics. First: a point of clarification. The second and third lines are important. When many say “Jesus is God” they just mean that in some sense or other Jesus is “divine.” (This could mean a lot of things, depending on one’s assumed metaphysics.) But this sort of person (line 3) understands Jesus to be “divine” in the sense of just being one and the same as God – that Jesus is God himself – one person, so just one (period).

In the italicized line, I’m applying  something called Leibniz’s Law, or the Indiscernibility of Identicals. I sometimes put this roughly as, some x and some y can be numerically identical only if whatever is true of one is true of the other. That’s a sloppy way to put it.

In logic, a more precise way of stating it (used e.g. by Richard Cartwright) is:

(x)(y)(z) ( x= y only if (z is a property of x if and only if z is a property of y))

Literally: for any three things whatever, the first is identical to the second only if the third is a property of the first just in case the third is a property of the second.

The basic intuition is that things are as they are, and not some other way. So if x just is (is numerically the same as) y, then it can’t be that x and y qualitatively differ. This seems undeniable.

There are a few problems, though, with the above formula, which any person trained in philosophy may spot. Read More »A formulation of Leibniz’s Law / the Indiscernibility of Identicals

DANIEL WATERLAND ON “THE FATHER IS THE ONLY GOD” TEXTS – PART 2

The Clarke-Waterland duel went on for many, many pages in several books, getting increasingly snippy.

Last time I said that I thought Waterland was a social-mysterian-trinitarian. But I’m not so sure about the “social” part! He’s very unclear on whether the “Persons” are selves. They’re different somethings, in any case. But in this series, I’m sticking to an exegetical issue.

Here are excerpts of Waterland’s second salvo about the “only God” texts.

[Clarke] had produced John 17:3, 1 Cor. 8:6, Eph. 4:6, which prove that the Father is styled, sometimes, the one God, or only true God; and that he is the God of the Jews, of Abraham, etc. I asked how those texts proved that the Son was not? You say… “very plainly… Can the Son of the God of Abraham (Acts 3:13) be himself that God of Abraham, who glorified his Son?” But why must you here talk of that God, as if it were in opposition to this God, supposing two Gods; that is, supposing the thing is question. …I tell you that this divine Person is not that divine Person, and yet both are one God(A Second Vindication of Christ’s Divinity in Waterland’s Vindications of Christ’s Divinity, 422-3, original italics, bold added, punctuation slightly modernized)

This is wheel-spinning. Clarke does, and Waterland does not take the passages in question to identity (assert to be numerically identical) the Father and Yahweh.

Clarke had asked whether Waterland thought that the term “Father” in these texts actually includes, i.e. refers to, the Son as well. Waterland clarifies,Read More »DANIEL WATERLAND ON “THE FATHER IS THE ONLY GOD” TEXTS – PART 2

Daniel Waterland on “The Father is the only God” texts – Part 1

Daniel Waterland (1683-1740) was by all accounts the most important disputant of Samuel Clarke about the Trinity.

Waterland spent his career at Cambridge, where he rose through the ranks, eventually becoming Vice-Chancellor, and also serving as a Chaplain to the King, and as an Anglican clergyman in a number of cities.

He had a good reputation, and was an energetic, but normally cool-headed controversial/polemical writer (aganist Clarke, and other other theological topics, against other respected men), and he gained somewhat of a reputation in Anglican circles as a defender of catholic orthodoxy.

Many, including himself, contemplating his becoming a bishop, but in 1740 he died after complications, seemingly, from surgeries on an ingrown toenail in one of his big toes! He was survived by his wife of 21 years. (His only children were his books.)

I’d describe Waterland’s views on the Trinity as social, with a liberal dose of negative mysterianism. Like Clarke, he insists that his is the ancient catholic view, and much of the dispute concerns pre-Nicene fathers. Like Clarke, he wants to stick to those fathers and to the Bible, and takes a dim view of medieval theology.

About the pre-Nicene catholic “fathers,” I’d say both Clarke and Waterland somewhat bend the material to their own ends (I mean, they tend to see those authors as supporting their view, and being perhaps more uniform than they were), but I think Waterland bends the materials more. In his view, catholics had always believed the Three to be “consubstantial” in a generic sense, yet which, somehow, together with their differences of origin, makes them but one god. Like Swinburne and Clarke, he agrees that the Father is uniquely the “font of divinity.” He continually hammers Clarke with the claim that there’s no middle ground between the one Creator and all creatures.

In this series, I’ll examine the way he deals with some favorite unitarian proof-texts, which, unitarians think plainly assert the numerical identity of the Father with the one true God, Yahweh. According to Waterland, these unitarians are making a mistake like the one I made.

You [i.e. Clarke] next cite John 17:3, 1 Cor. 8:6, Eph. 4:6, to prove, that the Father is sometimes styled the only true God; which is all that they prove. Read More »Daniel Waterland on “The Father is the only God” texts – Part 1

Last time, I mentioned a well done book by evangelical philosopher Gregg Ten Elshoff on the topic of self-deception and the Christian life.

SCORING THE BURKE – BOWMAN DEBATE – ROUND 6 Part 2 – Bowman

In his sixth and final installment of the debate, Bowman turns in his finest performance, making a number of interesting moves, and getting some glove on Burke.

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.

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.

SCORING THE BURKE – BOWMAN DEBATE – ROUND 4 PART 3 – BURKE

In round 4, Burke urges that his views about God, Jesus, and the Holy Spirit provide a simpler explanation of the texts. Whereas trinitarians must argue from implications of the text,

By contrast, I argue that the Bible provides us with explicit doctrines about the Father, Son, and Holy Spirit, which… I have shown to be firmly rooted in OT theology.

Burke has a point here, although it can be overstated. Burke’s theology allows him to stick more closely to the words of the NT and the message as preached, e.g. in Acts. Surely, considered by itself this is an advantage. Trinitarians will argue that it is outweighed by the fact that the unitarian message leaves out other essentials, if somewhat implicit ones. Burke complains that Bowman hasn’t defined “implicit“, but this is a general philosophical issue outside the realm of the debate. Burke emphasizes that his approach is “Hebraic” whereas Bowman’s is “Hellenic”. In some sense this may be true, but I don’t think it advances the debate. It is surely possible that God providentially used Greek philosophy to help uncover the true implications of the NT. Further, both debaters are to some extent using Greek-philosophy-originated concepts and logic. Another place in which they’re talking past one another is this issue of the importance of what is and is not explicit in the NT, and specifically in the preaching of the apostles. Bowman is surely right that, e.g. Peter need not assert every element of the apostolic teaching in one sermon, and that Luke’s summary of that sermon surely wouldn’t include all of it. But Burke is right that if it is an essential part of the faith, and necessary to believe for salvation, that e.g. the Holy Spirit is a fully divine person in God distinct from the Father and Son, then we would expect this to be explicitly taught by the apostles, up front, prior to baptism. And we do not find this. But I don’t believe that Bowman has said that one must believe this to be saved. But if he affirms it, and holds that the apostles teach it, then Burke has a strong argument against him. This is surely a pressing, practical question that should be raised.

SCORING THE BURKE – BOWMAN DEBATE – ROUND 4 PART 2 – BOWMAN

In part 1 I argued that Bowman attributes a non-existent fallacy to unitarians. After this faltering start, things get better. Continuing his pre-emptive rebuttal, Bowman argues that there is nothing about the roots of the Hebrew and Greek words translated “spirit” that requires them to mean a force or energy. Surely, this is correct, and his examples show this.

In the end of his pre-emptive rebuttal, Bowman attributes this argument to unitarians:

  1. The Bible contains no progressive revelation concerning God.
  2. The OT does not reveal the Holy Spirit as a distinct divine person.
  3. Therefore, the NT does not reveal the Holy Spirit as a distinct divine person.

I suspect that some current day unitarians do endorse this argument. (Does Burke?) Christians of any stripe who believe in any sort of Hell, in souls, or that the NT more clearly reveals the character of the Father, would probably reject 1. For these sorts of reasons, I reject it myself. In my view progressive revelation is different from the Islamic idea of “abrogation” (later Quranic verses contradicting and cancelling out or over-ruling earlier ones). Progressive revelation doesn’t involve contradiction of something earlier asserted, but rather clarifying something previously unclear, and contradicting things one might have inferred from what was formerly asserted. But back to Bowman.

Bowman opines that the OT unclearly hints at the Spirit being a distinct divine person, but he wants to say that this truth is only first clearly revealed in John 14-16. I think this puts him far off of patristic exegesis, btw – but maybe that’s a good thing.

The real meat of Bowman’s case is his exegesis of the books of John and Acts. His first positive argument is essentially this. Jesus promised that after leaving, he’d send “another Paraclete”Read More »SCORING THE BURKE – BOWMAN DEBATE – ROUND 4 PART 2 – BOWMAN

SCORING THE BURKE – BOWMAN DEBATE – Round 4 Part 1

In this post I venture to offer some debate advice: be very hesitant to accuse your opponent of a logical fallacy.

  • First, your lack of sympathy for his position can easily cause you to be see ones which are not really there.
  • Second, it is often unclear whether or not the dude is actually making an error in reasoning – begging the question is particularly tricky to diagnose, for instance, and some of the “flags” I’ve thrown in judging previous rounds are debatable.
  • Third, there is a temptation to quickly allege a fallacy rather than dealing with the truth or falsity of your opponent’s premises. (This can verge on making an ad hominem fallacy yourself.)
  • Fourth, you may be tempted to make up a new sort of error in reasoning new for the occasion, and accuse your opponent of it.

In round 4, Burke makes the 3rd error, Bowman the 4th.

Burke argues,

Even Acts 5, where the apostle Peter accuses Ananias of “lying to the Holy Spirit” (verse 3) and his wife of trying to “test the Spirit of the Lord” (verse 9) is not an open and shut case. The usual argument made from this passage is that Peter accuses Ananias of “lying to the Holy Spirit” and Sapphira of trying to “tempt the Holy Spirit”; but since an impersonal power cannot be lied to or tempted, the Holy Spirit must therefore be a person and therefore it follows that the Holy Spirit is God. The logic here is not terribly good, and the argument ends with a non sequitur.

Neither this nor what follows it make clear what Bowman’s errors in reasoning are supposed to be. What exactly is the argument he’s criticizing? Is it this?Read More »SCORING THE BURKE – BOWMAN DEBATE – Round 4 Part 1

SCORING THE BURKE – BOWMAN DEBATE – Burke 3

In round 3, Burke comes out swinging and swinging. But how much does he connect? In my judgment, somewhat. Here’s an overview of his case, with some critical comments, and at the end I score the round.

First, Burke argues that Jesus’ messianic roles as atoning sin-offering, priest, redeemer, and Davidic king, do not require him to be divine, and further, that the first and last of these require that he is not God. I take it Burke’s point is that they require Jesus to be a human, and that no human is divine. Flag: In this context, the point is question-begging. Bowman no doubt affirms Chalcedon, according to which Jesus has both a divine and a human nature.

Next, Burke has a nice discussion of the Jewish habit, well attested in the NT and in other ancient writings, of talking about what God has predestined as already existing in heaven. This affects what one considers the natural reading of passages like John 17:5 (NIV) “And now, Father, glorify me in your presence with the glory I had with you before the world began.” Burke nicely sketches the line of thought behind this habit – what is predestined is as good as done, so what is future is moved back, as it were, to the past or present – to a time which is “too late” to avoid. He gives a vivid example from Paul of talking about a future event as present: “And God raised us up with Christ and seated us with him in the heavenly realms in Christ Jesus…” (Eph 2:6, NIV)

SCORING THE BURKE – BOWMAN DEBATE – Burke 2

There’s a lot of meat in Burke’s second round, and both his and Bowman’s second rounds were cleaner, more free of stray punches than round 1. Here I offer some summaries and brief comments on Burke.

  • In a lot of the piece, Burke lays out his positive views about Jesus. This should give a lot of people pause; it is often assumed, contrary to the long but largely forgotten history of this minority report, that unitarians are mere “deniers”, or that they can be lumped together with the amorphous “skeptics” who appear in apologetics writings, or that they are theological “liberals”, or that they are Unitarian Universalists. Not so – arguably, Burke affirms all the really obvious doctrines of the New Testament – messiah, mediator, resurrection, atonement, etc. – roughly, all the items in the “Apostles'” Creed. Burke defends what used to be called a “humanitarian” christology – that Jesus was a human, and did not exist before his miraculous conception in Mary. It would be misleading to describe his position as being that Jesus was “just a man”. In Burke’s view, he’s far from being just a “great teacher” among many, with peers like the Buddha  and Muhammad, or even being merely a prophet.
  • It is striking to what degree Burke simply ignores some influential (but now largely forgotten) patristic ideas, to wit: the Jesus’ ministry obviously manifested the divine nature (through, e.g. his miracles), that Jesus must be divine so as to be able to divinize humanity, that Jesus and not the Father was the one who interacted with the Jews in OT times, that the title “Son of God” implies having the divine nature, that what is “divine” must be absolutely unchanging and simple. I say this more by way of observation than criticism. With the exception of the first, I expect that Bowman will largely ignore them as well.
