Secondly, stating that actual infinites cannot exist, which I'm not saying but you are...refutes almost every deity in every religion in existence.
An Eternal Creator does not exist in *this* *material* *Universe*, hence it is not an *actual* infinity, as our universe is not infinite and therefore nothing infinite is possible in it.
Things we regard as infinite sequence processes are only infinite potentially, not actually.
Actually, G.T., like Morriston and Malpass, is merely demonstrating his ignorance of classical theism, which is typical of your average atheist, but in the case of Morriston we have a twist.
G.T.'s just another slogan-spouting atheist arguing against something he doesn't understand. We see the same thing when atheists invoke the Euthyphro dilemma, for example, against the construct of divinity of classical theism. The Euthyphro dilemma only impinges on the created gods (or immortals) of paganism or the god of pantheism, i.e., on the materially contingent gods of irrationalism and myth. Logic tells us that God and goodness are not categorically distinct entities, but one and the same existent. Also, God is not an actual infinite either. Once again, the first principles of ontology per the imperatives of logic tell us that an actual infinite does not and cannot exist in any world, material or otherwise.
Morriston is actually a Christian, that is to say, a liberal Christian who thinks that God is an actual infinite. He thinks he's refuting Craig, when actually he's arguing against rational and textual orthodoxy in defense of
his liberal theology in this wise. In other words, Morriston is trying to cram his theology down reality's throat, rather than let God's uncreated logic that He bestowed on us to speak for itself and lead us where it will as God intended. This is why G.T.'s appeal to Morriston-Malpass' line of argumentation is so hilarious.
When classical theists speak of God as being infinite, they're not saying that He's an actual infinite; certainly learned, biblically orthodox Christians aren't. Rather, such theologians mean that He's infinite, not in the quantitative sense, but in the superlative sense of quality as compared to all other existents. In other words, God is incomparably superior, magnificent, wonderful. He's gloriously unique among all other existents, which, of course, He created from nothing but the sheer power of His will. God's omnipotence is not the power to do anything. It's the power to do all things possible. God's omniscience is not an innumerable collection of facts, but a single apprehension of all things possible at once. Only the contents of finite minds are comprised of bits and pieces of information.
G.T. raised Malpass' video when he thought he was springing something new and profound on me, but he lost interest in discussing it, apparently, when he realized it wasn't new or profound to me. LOL! In the final analysis, all they're really saying, aside from the nonsense that the past and future directions of time are symmetrical, is that the complete infinities of abstraction are actual because they exist in minds. But such only exist as theoretical apprehensions of possibility in minds, and even then only as ideas without any definitive quantity or amount. For example, we all understand that any line from point
A to point
B can in theory be "infinitely" divided without end. But at any given moment in the process of division, the number of segments into which the line has been divided is finite, and the sum of its segments are equal to the origin whole. No one is arguing that infinity doesn't exist, but that it doesn't exist as anything more than an idea of a boundlessly large and indeterminable number or amount of something in minds. Outside minds, an actual infinite does not and cannot exist in any sense but as a potential infinite tending toward infinity, but never reaching infinity, as, ultimately, infinity has no extremity.
I can't really speak to the rest of their argument regarding Craig's alleged beliefs. I've read a few of Craig's articles on cosmology and I've obviously studied his version of the Kalam argument. I've read and concur with his evaluation of Morriston's benighted critique. I know that he ascribes to the A theory of time, as I do, for the material realm of being. Beyond that I don't really know the details of his beliefs regarding the A theory, i.e., I don't know anything about Malpass' claim that Craig's view on the A theory includes a "presentist-like" notion regarding the existence of the past. I have my own notions that make sense to me, albeit, as informed by logic and God's word. Certainly the A theory of time applies to finite minds, not to that of God.
