Christology and Heresy 2 – Monophysites, Chalcedonians, and Nestorians (JT)

We're here to defend the faith against heresy!

The Council of Chalcedon (451 CE) condemned Monophysitism and Nestorianism. The following table helps to classify Monophysitism, Nestorianism, and Chalcedonianism.

Nestorianism: 2 natures, 2 persons
Chalcedonianism: 2 natures, 1 person
Monophysitism: 1 nature, 1 person

Christology and Heresy 1 – What is Nestorianism and Monophysitism? (JT)

If the circle and triangle overlap, that's bad. If they don't overlap, that's bad too.

These days, when analytic philosophers of theology talk about the Incarnation, they often say things like ‘if such-and-such, then such-and-such, but that would be Nestorianism’. The implication, of course, is that landing oneself in Nestorianism would be a very bad thing.

But why? Perhaps a lay person might want to avoid Nestorianism because they were told it was a ‘heresy’. But a hard-core Christian philosopher, I think, would want to be more explicit about saying just what Nestorianism is, and provide some reason for why they want to avoid it (rather than just asserting that some position is Nestorian).

Mysterians at work in Dallas

confused kid
Clearly, the instructor’s work has been accomplished.

What I call positive mysterianism about the Trinity is the view that the doctrine, as best we can formulate it, is apparently contradictory.  Now many Christian philosophers resort to this in the end, but only after one or more elaborate attempts to spell the doctrine out in a coherent way. On the other hand, some jump more quickly for the claim, not really expanding on or interpreting the standard creedal formulas much at all. These are primarily who I have in mind when I use the label “positive mysterian”.

I ran across a striking version of this recently, in a blog post by theologian C. Michael Patton, who blogs at Parchment and Pen: a theology blog. In his interesting post, he says that all the typical analogies for the Trinity (shamrock, egg, water-ice-vapor, etc.) are useful only for showing what the Trinity doctrine is not.

This contrasts interestingly with what I call negative mysterians. Typically, and this holds for many of the Fathers, as well as for people like Brower and Rea nowadays, they hold that all these analogies are useful, at least when you pile together enough of them, for showing what the doctrine is. Individually, they are highly misleading, and only barely appropriate, but they seem to think that multiplying analogies like these results in our  achieving a minimal grasp of what is being claimed. Maybe they think the seeming inconsistency of the analogies sort of cancels out the misleading implications of each one considered alone.

In any case, in Patten’s view, the best you can do is to Read More »Mysterians at work in Dallas

More on Mysteries

Thanks to Ed Feser for some interesting dialogue on the topic of mysteries in Christian theology. This post is just a bunch of miscellaneous responses to his thoughts posted last week, here and here. As he mentioned, Ed and I knew each other briefly as students at what is now called Claremont Graduate University.

Richard of St. Victor’s De Trinitate, Ch. 22 – part 1

Has Richard, after these 21 chapters so far of Book III of his On the Trinity (De Trinitate) only succeeded in proving that there are at least three gods? In chapter 22, Richard argues for a negative answer.

First, he refers back to the doctrine of divine simplicity, which is common coin for medieval theists, even, surprisingly, for trinitarians. This needs explaining nowadays – theists now tend to think of God’s nature as something he has, and of God as having, and not being, his attributes. Moreover, we tend to think that God has many attributes.

For a primer on divine simplicity, I can do no better than Bill Vallicella:

[According to this doctrine] God is radically unlike creatures in that he is devoid of any complexity or composition, whether physical or metaphysical. Besides lacking spatial and temporal parts, God is free of matter/form composition, potency/act composition, and existence/essence composition. There is also no real distinction between God as subject of his attributes and his attributes. God is thus in a sense requiring clarification identical to each of his attributes, which implies that each attribute is identical to every other one. God is omniscient, then, not in virtue of instantiating or exemplifying omniscience — which would imply a real distinction between God and the property of omniscience — but by being omniscience. And the same holds for each of the divine omni-attributes: God is what he has. As identical to each of his attributes, God is identical to his nature. And since his nature or essence is identical to his existence, God is identical to his existence. (William Vallicella, “Divine Simplicity”, Stanford Encyclopedia of Philosophy)

Richard starts ch. 22 by gesturing back at book I of De Trinitate – his point is that this divine being/essence/nature common to the three is utterly simple. Yet he realizes that this by itself won’t soothe the concern about monotheism. How can we rule out that there are three gods, each of which has is an utterly simple, composition free being? Then he hits on an additional argument.Read More »Richard of St. Victor’s De Trinitate, Ch. 22 – part 1

Richard of St. Victor’s De Trinitate, Ch. 21 (Dale)

In the preceding chapters, Richard has been arguing for the impossibility of only one divine person. If there’s one, there must be more than one; more than that, there must be at least three.

To do this, he’s used Anselmian perfect being theology – arguing that since God is absolutely perfect, and it would add to his perfection to have certain features, he must indeed have those. It seems that he prefers a three parallel arguments, from perfect goodness, perfect happiness, and perfect glory. (See, e.g. chapter 5.)

As the book goes on, though, it seems to me that he prefers the argument from happiness. Here, in chapter 21, he sums up his case, because he feels some pressure here at the end of the book  to explain why all this should be considered monotheism, and not polytheism. More on that next time. Here’s what looks like his summary of his argument:

The fullness of supreme happiness requires fullness of supreme pleasure. The fullness of supreme pleasure requires fullness of supreme charity. The fullness of supreme charity demands fullness of supreme perfection. (p. 393)

This last part isn’t easy to see, but as we’ve been over it, I let it go here. In chapter 21, Richard assumes that perfect being reasoning should be applied to each member of the Trinity. If we do this,  then we prove the existence of equally perfect beings, such that “all coincide in supreme equality. In all of them there will be equal wisdom, equal power, undifferentiated glory, uniform goodness, and eternal happiness…” (pp. 393-4, emphasis added)

This, he asserts, meets the requirement of the “Athanasian” creed,Read More »Richard of St. Victor’s De Trinitate, Ch. 21 (Dale)

“Trinity” @ the Stanford Encyclopedia of Philosophy

Little known fact: overwork causes one’s neck to become invisible! After an embarrassing amount of time, I’ve finally finished my encyclopedia entry on the Trinity for the Stanford Encyclopedia of Philosophy (as well as lengthy supplementary documents on the history of Trinity doctrines, Judaic and Islamic objections, and unitarianism). Since I can’t thank them in the entry, I’d like to thank editors Ed Zalta and… Read More »“Trinity” @ the Stanford Encyclopedia of Philosophy

Richard of St. Victor 3 – Perfect charity must be directed at another person (JT)

“Steven, let’s look over there and pretend like we don’t see that floating head.”
“Steven, let’s look over there and pretend like we don’t see that floating head.”

STAGE 2. In this stage, Richard tries to show that perfect charity must be directed at another person. Here’s the quotation:

‘no one is properly said to have charity on the basis of his own private love of himself. And so it is necessary for love to be directed toward another for it to be charity’.

Arius and Athanasius, part 11 – General questions about divine production (JT)

In this series of posts, I’ve been discussing the view of Arius that the Son is created from nothing, and the view of Athanasius that the Father begets the Son. All of this illustrates two basic issues that any classical account of the Trinity has to face when it tries to explain how one divine person produces another. First, we need to think carefully before… Read More »Arius and Athanasius, part 11 – General questions about divine production (JT)

Arius and Athanasius, part 10 – The Father and Son can’t share all their properties (JT)

Son, I know you want it, but you just can't have my triangle.
Son, I know you want it, but you just can't have my triangle.

Last time, I explained that Athanasius has not made it clear how the Son ‘inherits’ divine properties from the Father. Yet even if Athanasius could explain how the Son ‘inherits’ properties from the Father, there’s still another problem. Like Arius, Athanasius believes that the Father is simple, and so anything ‘in’ the Father is, strictly speaking, identical to the Father. If the Son is going to inherit any properties from the Father, then surely he’d have to inherit them all. As Athanasius himself realizes, it’s not a question of the Son inheriting part of the Father. It’s a question of all or none.

However, there are certain properties the Son cannot inherit from the Father, on pain of contradiction. For instance, the Son cannot inherit the Father’s unbegotteness. The Son is begotten, but the Father is not, so the can’t inherit the Father’s unbegotteness without entailing a contradiction.

The Father and Son look just alike!
The Father and Son look just alike!

In the last two posts, I looked at Athanasius view that the Father begets the Son much like how human fathers beget human sons. But Athanasius’ view raises some interesting questions.

One of the things Athanasius likes about natural procreation is that sons get their natures from one of their ingredients, namely the substance they get from their fathers. For example, in God’s case, the Father is an ingredient in the Son, and the Son inherits his divine properties from that ingredient. However, the Son is not identical to the Father, and it’s not clear to me how the Son is supposed to ‘inherit’ properties from something he’s not identical to.

This diagram from the 1970s says it all.

Last time, I explained that Athanasius thinks human fathers procreate sons by giving a part of their substance to the mother, and that bit of substance then becomes an ingredient in the zygote, and the zygote inherits its human nature from that ingredient.

Athanasius thinks this basic model applies to God too, though he is careful to make an important qualification: human fathers beget sons by giving up a part of their substance, but God the Father gives his whole self to his Son, not a part.

Hey mom! I got my substance from daddy!
Hey mom! I got my substance from daddy!

In the last two posts, I explained that Arius believes the Son is created from nothing. Athanasius, for his part, denies this. As he sees it, the Son is begotten, and here, ‘begetting’ (or ‘generating’, as it’s also called) is a technical term for the natural process of procreation, as when living organisms produce offspring. For Athanasius, the Son really is a son; he’s the natural offspring of the Father.

Air dancing is the best!
Air dancing is the best!

Last time, I explained that Arius believes there can only be one unproduced producer, and that’s the Father. The Son, by consequence, is produced, but there’s nothing controversial about saying that. Arius gets controversial when he tries to explain how the Son is produced. As Arius sees it, if the Father produced the Son with any ‘pre-existing ingredients’, he’d either have to use created ingredients, or he’d have to use some ingredient taken from within himself (those are the only two options). But Arius thinks neither of these are open to the Father.

Son, I know it's hard, but could you just TRY and smile for the camera?

So far, we’ve established that something is created from nothing if it’s produced without any pre-existing ingredients (see this one for a quick summary). Arius, for his part, believes that the Son is produced in just this way. In this post, I want to start looking at Arius’ argument for this conclusion.

Arius and Athanasius, part 4 — A definition of creation (JT)

In the last two posts, I explained what I mean by ‘pre-existing ingredients’. In the first of those two posts, I said that an ‘ingredient’ in a product is something that is (i) in the product, and (ii) not identical to another ingredient or to the whole product.

It's easy to make things with pre-prepared ingredients!

In the last post, I explained that something is ‘created from nothing’ when it’s produced without any pre-existing ingredients. I also explained that by ‘ingredient’ I mean any sort of constituent which satisfies the following two conditions: first, it exists in the product; and second, it bears its own properties, i.e., it has features that other ingredients in the product do not have, and which the product itself does not have. In this post, I will explain what I mean by ‘pre-existing’.

Well Dad, I just don't understand why we had to make them so small.
Well Dad, I just don't understand why we had to make them so small.

As I said last time, Arius maintains that the Son is created from nothing (ex nihilo), but Athanasius denies this. Much of the discussion depends on what these authors mean by ‘creation’. Before we go any further then, it will be helpful to establish a working definition for ‘creating something from nothing’. This requires some care, because we’re after a definition that both Arius and Athanasius would agree to. But so long as we make the right qualifications, I think that Arius and Athanasius do agree on what it means to create something from nothing.

Just so we have a rough idea of what we’re talking about, let me begin by describing creation in the following way: something is created from nothing if it’s produced without any pre-existing ingredients. Now, that’s a very loose way of putting it, but it makes the basic idea clear enough. We know that things get produced with pre-existing ingredients all the time. Masons build walls with bricks and mortar, cavemen make charcoal with fire and wood, humans procreate with sperm and eggs, and so on. But none of that counts as a creation. Something is created from nothing only when it’s produced without any pre-existing ingredients.

Arius and Athanasius, part 1 — How is the Son produced? (JT)

Even though it should be obvious from our three faces, we like to carry around this large diagram, just to be clear.
Even though it should be obvious from our three faces, we like to carry around this large diagram, just to be clear.

This series is extracted from a paper I delivered at the APA in Chicago last month. I’ve basically just cut up the paper into smaller chunks.

As we all know, the doctrine of the Trinity states that God is three persons: the Father, Son, and Spirit. Further, two of these persons, the Son and the Spirit, are produced. According to both East and West, the Son is produced by the Father, but the East holds that the Spirit is also produced by the Father, while the West holds that the Spirit is produced by the Father and Son together. But that’s by the by. The point is that some of the divine persons are produced.

The question that interests me is this: how, exactly, does one divine person produce another? In this series, I want to look at two 4th century attempts to explain how the Father produces the Son: that of Arius, and that of Athanasius.

Dealing with Apparent Contradictions: Part 20 – Resolution by Revision


Three famous Revisers: Socinus, Luther, and Hick.
When it comes to apparently contradictory claims in theology, there’s more than one way to Resolve the apparent inconsistency. The more popular way nowadays among Christian philosophers is what I called Rational Reinterpretation. The other way to Resolve? Revision. We’re faced with P, Q, and if P then not-Q. Solution? Simply deny either P or Q (or both). Problem solved.

Unlike Redirectors, Revisers don’t change the subject. Unlike Resisters, they don’t claim we should just “live with the tension”. Unlike practitioners of Restraint, they don’t think we can put off the issue. Like Resolvers through Rational Reinterpretation, they have a solution. But they don’t think tricky, new, more careful formulations are what is called for. Rather, something must go out on the rubbish heap. Revisers are usually accused of arrogance, lack of respect for tradition, biblical ignorance, idolatry of human reason, not being Christians at all, and of hating babies and cute little puppies.
