I understand that wants to protect the full, uncompromised deity of Jesus Christ against Islamic and atheistic critics and that, in his view, if the Son’s divine nature is “derived” or “generated” from the Father, the Son becomes inherently dependent and secondary. To fix this, Craig removes the doctrine of eternal generation and grants independent self-existence (aseity) to all three Persons.
The problem is that, by trying to save Christ’s equality, Craig inadvertently destroys the mechanics of Christian monotheism.
Let’s start from one premise: God’s essence is a simple, undivided unity. Because God cannot be divided into pieces, the only thing that distinguishes the Father, Son, and Holy Spirit is their relations of origin (the Father eternally begets, the Son is eternally begotten).
If you eliminate these internal relations, you remove the very mechanism that keeps the three Persons bound to the same singular substance, and without eternal generation, the divine essence becomes an abstract generic category (like “human nature”) rather than an indivisible reality.
Because Craig rejects relations of origin, his alternative model, known as Trinity Monotheism, posits that God is a single soul endowed with three distinct centers of consciousness, three distinct minds, and three distinct wills.
And this right here is the textbook definition of tritheism: if you have three distinct centers of consciousness that exist completely independently of one another, you no longer have one God in the monotheistic sense; you have three divine individuals instead.
Also Craig defends his monotheism by arguing that the three Persons are perfectly aligned in love, thought, purpose, and will, but the thing is thwt Harmony is not unity. A committee of three divine beings who always vote unanimously and love each other perfectly is still a committee of three separate gods. Their oneness becomes social and voluntary rather than essential and metaphysical.
By severing the eternal generation of the Son, Craig’s model effectively replaces the singular God of Nicaea with a perfectly unified, celestial team of three self-existent deities.
One question I would like to ask him is: how about we don’t assume that we “know better” by virtue of being “modern”, making a mockery out of Christ’s promises in the process?
