I'm about 92 pages in, and there's a lot in there, even though this is the abreviated version of the Summa Theologica. There is much that's gone straight over my head, I'm sure, and this will be one of those works that I reread multiple times, as I learn more and more.
However, interesting thing I've come away with thus far: God exists as pure action, there is never any potential action in God. He doesn't think of doing something, and then as a separate action, do it, He thinks, and it is done. Pure action, no potential.
Now I'm reading about how the human soul is incorruptible, meaning that it is not able to be destroyed. It exists, within the body, and then when the body dies, without it.
