One God, Three Persons, Four Views
The one where four professors of philosophy present their Trinitarian views (or in Dale Tuggy’s case, Unitarian view) and engage with the views of their counterparts.
My biggest disappointment is that no one was found to present a Latin/Thomist flavor of Trinitarianism. The editor of the book lamented this lack as well. I would particularly liked to have seen someone (James Dolezal would be my vote) of that persuasion interact with Beau Branson and vice versa. William Hasker and William Lane Craig offered slightly different Social Trinitarian views, Beau Branson presented his case for what he calls Monarchian Trinitarianism, and Dale Tuggy his denial of Trinitarianism altogether.
William Hasker, the one author I had not heard of before, wrote the opening essay and didn’t get off to a great start. He claimed Gregory of Nazianzen said, “When we say God, we mean Father, Son, and Holy Ghost” but the relevant footnote simply said “Quoted by Wright, ‘On Whether or How Far We Can Know God.’” Not sure what do to with that. I really wanted to see the context of this alleged quote but came up empty-handed. Why quote someone quoting an early church father as if you’re quoting an early church father? He then uses Gregory of Nyssa in support of his claim that the Father, Son, and Holy Spirit have different wills (albeit in harmony) but I don’t think this was what Gregory meant in the referenced passage (Not Three Gods: To Ablabius.) Gregory went to lengths in that passage to describe activities, operations, or attributes of the three persons to be spoken of in the singular because they are undivided and mutual. If Hasker wants to deny inseparable operations and posit each divine person as having a separate center of consciousness and a separate will, that’s his prerogative but I strenuously question his attempt to use Gregory of Nyssa to say it. Beyond that his chapter had some good contributions. He sums up his position, “The doctrine of the Trinity affirms that the three Persons are together a single concrete being—that they share between them a single trope of deity, a single concrete instance of the divine nature. This claim can be modeled by the notion of a single mental substance, or soul, supporting simultaneously theee distinct conscious lives, three streams of experience.”
William Lane Craig followed with his chapter spending the bulk of his time arguing for the full deity of Christ most especially with careful exegesis of every passage in the NT where Jesus is clearly or may be referred to as ho theos, that is God with a definite pronoun. I really enjoyed that portion of his chapter. Moving onto his model, he seeks to have a very basic description, and sums up his version of the Trinity which he calls “tri-personal monotheism” with the terse statement “God is an immaterial, tri-personal being.”
Beau Branson begins the next chapter by saying he can’t speak about the Trinity itself, but can speak on the doctrine of the Trinity. His interlocutors’ replies seemed to find this very weird or even hypocritical, but I just took this as him following in the Cappadocians footsteps and saying the divine essence itself is ineffable, but the doctrine of the Trinity has been spoken of in human language (for Scriptural and historic polemical reasons) and we can say something more confidently about that even if we (obviously) can’t completely figure out God. Branson argued for Monarchial Trinitarianism (monarche meaning one-source) where God the Father is God[ultimate source] but eternally generates the Son and from whom the Spirit proceeds eternally, all equally divine and properly called God as there is one God[nature] and that the three persons act inseparably. He says “Despite differences in their metaphysics, the fathers we have in view all agree that: There is only one God[Ultimate Source], the Father, and: The Trinity is one God[Nature], because the divine nature is undivided among the Trinitarian hypostases. Furthermore (as we will see below), they also hold: The Trinity is one God[power/action] because the Trinitarian operations are also undivided (or ‘inseparable’) among the Trinitarian hypostases. Thus, no matter how we disambiguate “God,” the result is that Trinitarianism worship only one God.” I really enjoyed chewing on Branson’s contribution for his philosophical parsing out of certain ambiguities and as I do think he holds a pretty historical position.
Dale Tuggy gave the fourth and final “model” which denies Trinitarianism altogether, claims the Father alone is God, and neither the Son nor the Holy Spirit is fully divine. I think William Lane Craig’s work to the deity of Christ and his direct response to Tuggy was pretty effective. Beau Branson’s argument about the early church’s use of nomina sacra (writing Lord, God, Jesus, and Christ as the first and last letters with a horizontal over line) was also helpful. Tuggy responded that he didn’t need to defend his Christology because this was a book about the Trinity, but the point is relevant that if Jesus was worshipped and honored as God it doesn’t seem reasonable to state that the early church only believed the Father is God. Of course, much more could be said about Tuggy’s back and forth with the other authors, but those are my quick highlights. I’m fundamentally unimpressed and uninterested in the position.
After the four initial essays, there was a direct response from each author to the other three. Finally, each author gave a few closing remarks and responses. I think the format worked well for this project. Some of the responses were quite passionate. Which sometimes led to a little humor. Overall, I enjoyed it, most especially Branson and Craig’s contributions.
