Assessing the Transcendence-vs.-Personhood Argument for the Impossibility of God

Source: Alchetron

In this post, I want to assess an argument for atheism called the Transcendence-vs.-Personhood Argument (hereafter, "TvP Argument"). The first section is an exposition of the argument as formulated by Theodore Drange. The second section is a partial assessment of the argument. The work of William Lane Craig appears prominently in this section. Craig is a highly regarded philosopher of time and philosopher of religion who has written extensively on the relationship between God and time. He is also, of course, a theist. Thus, his work on divine eternity provides a useful "test case" for the TvP Argument. 

Richard Gale's Sovereignty-Benevolence Argument

Richard Gale presents the following argument to show that objective moral truths are not the sort of things that could be created.

(1) God determines the truth-values of ethical propositions.
(2) God is essentially benevolent.
(3) God is omnitemporal, i.e., his eternality involves beginningless and endless duration in time.
(4) God is benevolent prior to his decision as to what truth-values ethical propositions will have. [From (2) and (3)]
(5) Nothing is good or bad, right or wrong, prior to God's decision as to what truth-values ethical propositions will have. [From (1)]
(6) Therefore, it is impossible for God to exist. [From (1), (2), and (5)]
