Tim Pawl: a God-man is possible

Catholic analytic philosopher Tim Pawl (University of St. Thomas, in Minnesota) argues that this is logically consistent: Jesus has both a divine and a human nature.

His answer is challenged by another talented young Catholic philosopher, Tomas Bogardus, of Pepperdine University. With their permission, I’ve reposted their dialogue from Facebook. I thought it deserved a wider audience.

From that same thread, I learned that Dr. Pawl is working on a book on the metaphysics of the Christology that comes from the “ecumenical” councils. I’ve thought and taught a good bit about those in recent  years, and plan to discuss them in upcoming podcasts, so I look forward to seeing this book, and the discussion it will generate.

Which is mightier – this beard or this one?

You decide. I’ll weigh in with a comment later.

Here, unedited but for the addition of a few explanatory links (and a gratuitous picture), is their dialogue:Read More »Tim Pawl: a God-man is possible

William Lane Craig in the Chronicle of Higher Education

Here. On the whole, a well done piece. Craig is indeed a fearsome debater, and a bold and insightful scholar. His devotion to apologetics makes him a bit uncool among professional philosophers. But I would guess that his work is probably read by more average people – Christians, atheists, Muslims, and who-knows-what – than any living philosopher. The reason is that it has many good… Read More »William Lane Craig in the Chronicle of Higher Education

Jerry Walls: What is wrong with Calvinism?

Devastating. I have long noted that Augustinian/Calvinist theology is unpopular among Christian philosophers, though many, like me, go through a Calvinist phase (when I was a sophomore and junior in college), before seeing its problems to be hopeless. Walls concisely and fairly sums up what Calvinism is all about, and then shows it to be profoundly problematic, focusing on philosophical problem rather than biblical ones.… Read More »Jerry Walls: What is wrong with Calvinism?

Simplifying the Indiscernibility of Identicals

equals - greenI’ve posted quite a few times here before about identity, and about the principle often called “Leibniz’s Law” – the Indiscernibility of Identicals. This is often put:

Necessarily, for any x and any y, x is identical to y only if for any P, x has P if and only if y has P. (Compare, e.g. Colin McGinn, Logical Properties (New York: Oxford University Press, 2000), 4-7.

I agree with other philosophers that this has apparent counterexamples, if “P” can stand either for any predicate or for any property.

But in my view, the underlying metaphysical intuition – that a thing can’t at one time be and not be a certain way – is undeniable. (And of course, it has important theological implications.)

I would restrict the “P” above to intrinsic properties, if I believed in properties. But I don’t. So I’ve been putting the principle like this:

The Indiscernibility of Identicals: Necessarily, any A and B are identical only if they (1) never have differed, (2) don’t differ, (3) will not ever differ, and (4) could not differ.

This formula doesn’t import any assumptions about property-theory, either for or against. Rather, it uses only a primitive concept of differing, or being different – as to qualitative aspect or way of being, not as to number. I think this well captures the intuition and fundamental conviction noted above.

But it now strikes me that the formula is needlessly complicated. Why not just this?Read More »Simplifying the Indiscernibility of Identicals

God and his Son: the Logic of the New Testament – conference presentation

Here’s a video of my May 2012 talk in Atlanta, “God and his Son: the Logic of the New Testament.” Many thanks to Sharon and Dan Gill, who filmed, edited, and posted it on their fine website, 21st Century Reformation. The characteristic thesis of unitarian Christianity (aka Biblical Unitarianism, Christian Monotheism) is that the Father of Jesus just is the one God, Yahweh, and Jesus… Read More »God and his Son: the Logic of the New Testament – conference presentation

Who Should Christians Worship?

Should Christians worship only God? Or God and Jesus? Or is it redundant to say that we should worship both God and Jesus? If Jesus isn’t God himself, is it therefore the sin of idolatry to worship Jesus? I address these questions in light of scripture in this screencast version of a talk I gave in Atlanta at the 2012 Theological Conference sponsored by the Atlanta Bible… Read More »Who Should Christians Worship?

A Tale of Three Kims – Part 2


To continue:

Jun-suh had heard rumors that both Kim Il-Sung and then later Kim Jong-Il had died. Jun-suh reasoned that since the Great Leader could not die, some foolish people must have mistaken the economic Leader (Leader as manifested to North Koreans, i.e. Kim Jong-un) for the immanent Leader (which is incomprehensibly great). In himself, he is one Leader but is three men. He has manifested himself as such, and we can trust that the economic Leader is the immanent Leader, and vice-versa. He remembered reading this somewhere, and was firmly convinced of it.

His Leaderology was now highly developed. But his friend Seo-yun made one last try to convince him Read More »A Tale of Three Kims – Part 2

The Trinity Explained (with Reason)

The word is “Therefore…” When you are making a deductive argument, this means that what you are about to say logically follows from (is implied by) what you have just said. That is, if the former part were to be true, what you’re about to say must also be true. A non sequitur (Latin for: “it doesn’t follow”) is an invalid argument, one in which the premises don’t imply… Read More »The Trinity Explained (with Reason)

Patton’s problem with Apologists

(click for image credit)

I recently stumbled upon a great post by Michael Patton that just about perfectly expresses how I’ve felt about Christian apologists since growing past teenagerhood.

In part:

This is the problem that I have with some apologists (those who defend the faith). Don’t get me wrong, I believe very much in apologetics and also love many apologists. But very rarely do I find a reasonable apologist. Most are very hardened because they are committed first to defending their particular position, not so much to learning.

Read the whole thing. He also has done a similar post recently.

I would add: apologists too often fall into mere rhetorical violence: hyperbole, attacking a straw man, verbal aggression, smug, acid condescension, simply repeating oneself more loudly, insults, poisoning the well, and so on. And this is leaving aside poorly constructed arguments. Sadly, debates between philosophers (one or both of whom may be atheists) are nearly always “cleaner” (more reasonably and respectfully conducted) than your average debate between a Christian apologist and anyone else.

I’m always reminded of what James says:Read More »Patton’s problem with Apologists

Defining the concept of a Christian unitarian

Thanks to reader Mike Gant  for his question about my last post. As of now I think I’ve got a solid definition of the concept unitarian: someone who believes that the one God just is (i.e. is numerically identical to) a certain self and not to any other self. But I then tried to define the more specific concept of a Christian unitarian: someone who believes that… Read More »Defining the concept of a Christian unitarian

A Tale of Two Tattoos (Dale)

I love philosophy majors. The best of them almost always develop a nerdy and warped sense of humor – and I mean that in the best way. 🙂

These two young ladies, recent alumnas of our department, decided to get complementary tattoos. (Sober, they swear!)

In each case, the tattoo artist left off the two initial universal quantifiers: AxAy (I can’t find the symbol codes for the upside down A representing the universal quantifier – so please imagine those A’s upside down.) They would read: For any x whatsoever and for any y whatsoever…

Now to the tattoos. “F” is supposed to be, either a predicate or a property. On the right tattoo (wrist) the right, closing parentheses is just out of view.

One of the tattoos says something nearly all philosophers agree is true (a rarity!) while the other is held to be false by many. Here’s your homework, dear reader:Read More »A Tale of Two Tattoos (Dale)

Scott Williams’s new paper: Henry of Ghent on Real Relations and the Trinity

Congratulations to Scott Williams, trinities contributor and newly minted Oxford University PhD in Theology,  on his forthcoming paper:  ‘Henry of Ghent on Real Relations and the Trinity: The Case for Numerical Sameness Without Identity’, in: Recherches de Théologie et Philosophie Médiévales 79.1 (2012), will be published.

Worship and Revelation 4-5 – Part 7 – Charles Morgridge on Revelation 4-5

19th c. American minister Charles Morgridge makes an apt comment about Revelation 4-5: There is not in the Bible a clearer distinction between the only true God, and his only Son our Saviour, than is here expressed. GOD sat on the throne; the Son stood amidst the elders. GOD had in his right hand a book; the Son came and took the book out of his… Read More »Worship and Revelation 4-5 – Part 7 – Charles Morgridge on Revelation 4-5

Worship and Revelation 4-5 – Part 5 – An Objection

(click for image credit)

If we stick with objections arising from the text of Revelation itself, perhaps the most obvious one is that raised in a comment on previous post by my friend James Anderson. Reformulated by me, it goes:

The text itself (Rev 19:10, 22:9) asserts that we should worship only God. And yes, Revelation plainly implies that Jesus should be worshiped. And so it plainly implies that Jesus is God. 

One might look to one of my favorite translations, the New Living Translation, which has these two verses saying, in part: “Worship only God”.

When you look at the Greek, though, you see that it simply says “Worship God.” Not the same thing! And most translations get this right. (Even The Message and the Good News Bible get it right.)

Where does the “only” come from? From the theological agenda of the translators; they want the text to be making the argument above. So in the ESV Study Bible, which translates these phrases correctly (“Worship God.”) they feel the theological need to add this footnote:

Human beings must not worship even the angels… God alone must be worshiped. Since the Lamb is rightly worshiped (5:8-14), he is God. (p. 2497)

Interestingly, these evangelical commenters agree with those in the recent Jewish Annotated New Testament that Revelation asserts that only God should  be worshiped. In their comment on 19:7-10, they assert that

It is God, not the Lamb/Jesus, who is to be worshiped. (p. 493)

And bizarrely, in their notes on chapter 5, they ignore the obvious fact that Jesus is being worshiped together with God, although they correctly note that

The heavenly song makes a clear distinction between the enthroned one and the sacrificial lamb. (p. 474)

I’m reading between the lines here, and the commenters in this book are understandably very circumspect, but I think their assumption is Read More »Worship and Revelation 4-5 – Part 5 – An Objection

Worship and Revelation 4-5 – Part 4 – Implications

Last time we carefully read through a heavenly scene in which Jesus is exalted to God’s side and worshiped alongside him.

We saw that it is indisputable that Revelation 4-5 holds forth Jesus as worthy of being worshiped.

But can this help us choose between the dueling arguments from the first post? Yes!

Given that we accept that Jesus ought to be worshiped, we must choose between Only God should be worshiped and Jesus isn’t God because we can’t consistently accept both of these, in addition to the claim that Jesus ought to be worshiped.

Based on our careful reading (Part 2, Part 3) of Revelation 4-5, let us ask which of these John would agree with?

Would John agree that only God should be worshiped?
Plainly not. 

  • Jesus is presented throughout as someone else. In these chapters, he comes into God’s throne room, receives the scroll of God’s secret plans from God, and is then honored alongside God.
  • God, the one on the throne, silently approves of all this. He lets Jesus take the scroll. It is his mission that Jesus accomplished, because of which Jesus is worthy to now be exalted. And he stands by while people worship both him and Jesus. And he does not thunder “You lousy idolaters” – worship only me!” And he, he tacitly approves of this exaltation of Jesus.
  • Smartly, the people present agree. (v. 14) No one calls out God Read More »Worship and Revelation 4-5 – Part 4 – Implications

Worship and Revelation 4-5 – Part 3 – Revelation 5

(click for image credit)

Last time, in chapter 4, our author (a “John” – 1:1) was granted a vision of God in heaven, receiving worship in his throne room.

In chapter 5, God – the one on the throne – is holding a sealed up scroll – a scroll which we later find out (ch. 6-9) contains his future plans. This is what the author was promised at the start of chapter 4 – that he’d be shown the future (4:1), again, something we know from Isaiah is the prerogative of God alone.

No one is found worthy to open it, and John is bummed. Someone tells him,

“Weep no more; behold, the Lion of the tribe of Judah, the Root of David, has conquered, so that he can open the scroll and its seven seals.”

And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth.

Lamb. Who? We’ve met him before – it is Jesus, the one through whom Read More »Worship and Revelation 4-5 – Part 3 – Revelation 5

Worship and Revelation 4-5 – Part 2 – Revelation 4

What does Revelation imply about God, Jesus, and worship? In Revelation chapter 4, the author is granted a heavenly vision: After this I looked, and behold, a door standing open in heaven! And the first voice, which I had heard speaking to me like a trumpet, said, “Come up here, and I will show you what must take place after this.” At once I was… Read More »Worship and Revelation 4-5 – Part 2 – Revelation 4

Worship and Revelation 4-5 – Part 1 – setup

What, if anything, is wrong with this argument? 1. Only God should be worshiped. 2. Jesus should be worshiped. 3. Therefore, Jesus is God.     (1,2) Before you answer, be sure you understand the claims fully. The “only” in 1 makes a claim of quantification, which we all understand in terms of identity. In standard logic, it would be analyzed as: Wg & (x)(Wx… Read More »Worship and Revelation 4-5 – Part 1 – setup
