Summa Theologica

By Thomas Aquinas

THE INFINITY OF GOD (FOUR ARTICLES)

After considering the divine perfection we must consider the divine infinity, and God's existence in things: for God is everywhere, and in all things, inasmuch as He is boundless and infinite.

Concerning the first, there are four points of inquiry:

(1) Whether God is infinite?

(2) Whether anything besides Him is infinite in essence?

(3) Whether anything can be infinitude in magnitude?

(4) Whether an infinite multitude can exist?
