Accordingly, if the divine essence is distinct from its existence, it follows that His essence and existence are mutually related as potentiality and act. Now it has been proved that in God there is nothing of potentiality, and that He is pure act. Therefore God’s essence is not distinct from His existence.

Again. Although that which is sometimes potential and sometimes actual, is in point of time potential before being actual, nevertheless actuality is simply before potentiality: because potentiality does not bring itself into actuality, but needs to be brought into actuality by something actual. Therefore whatever is in any way potential has

The first way is as follows. Whatever is in motion is moved by another: and it is clear to the sense that something, the sun for instance, is in motion. Therefore it is set in motion by something else moving it. Now that which moves it is itself either moved or not. If it be not moved, then the point is proved that we must needs postulate an

For matter, such as it is, is in potentiality.

Therefore if one of its parts is at rest, it follows that the whole is at rest. For if, while one part is at rest, another of its parts were in motion, the whole itself would not be moved primarily, but its part which is in motion while another is at rest. Now nothing that is at rest while another is at rest, is moved by itself: for that which is

Now every necessary thing either has a cause of its necessity from without, or has no such cause, but is necessary of itself. But we cannot go on to infinity in necessary things that have causes of their necessity from without. Therefore we must suppose some first necessary thing which is necessary of itself: and this is God, since He is the first

The first of these is proved by the Philosopher in three ways. First, thus. If a thing moves itself, it must needs have the principle of its movement in itself, else it would clearly be moved by another. Again it must be moved primarily, that is, it must be moved by reason of itself and not by reason of its part, as an animal is moved by the

Only things which are moved are measured by time: because time is the measure of movement, as stated in 4 Phys. Now God is absolutely without movement, as we have already proved. Therefore we cannot mark before and after in Him. Therefore in Him there is not being after non-being, nor can He have non-being after being, nor is it possible to find

And the divine intellect surpasses the angelic intellect much more than the angelic surpasses the human. For the divine intellect by its capacity equals the divine essence, wherefore God perfectly understands of Himself what He is, and He knows all things that can be understood about Him: whereas the angel knows not what God is by his natural
