This talk of God being “pure act” seems untenable to me. I mean, God had the potential to create our universe, and he did. He had the potential to create a different one, but he didn’t. He does not actualize all potentialities, therefore he is not pure act. Is God being pure act a dogma or what?
This has gone off-topic, but whatever.

As levinas said, it’s connected to your question. We conclude that potentiality was created by God outside of Himself, done so out of freedom with
Agape love. Not only does that establish personal connection but what else proves why God must be personal is that creation was not a once-and-for-all event able to direct itself. God is ever present in our existence, directing unintelligible unconscious things to final causes, even ourselves but not invalidating our free will but only leading us to choices in our lives to freely choose what He wants or what we want.
The question by belorg is how did potentiality come to be if all there was, was actuality (or more plainly, all that was, was God)?
Belorg’s conclusions are (
please correct me if I’m wrong belorg, sorry if there is a screwup)
- Potentiality is co-eternal with the Pure Actual Being.
or
- The Pure Actual Being was the recipient of change.
1 is false because potentiality cannot be the necessity of itself, nor can it move/change itself. Thus potentiality came to be not of own it’s action, but an outside agent that is Pure Act.
2 is false due to many reasons but most evident (in my own opinion) is that if this is the case, this would follow a
creatio ex deo atemporal existence. This would entail a incorruptible good universe since God is incorruptible, which is false for we have corruptible good. Thus we have
creatio ex nihilo, the separate state of existence that is corruptible from the perfect being who is incorruptible.
Conclusion, potentiality was created outside the Pure Actual Being. “Outside” encompassing an unexplainable way how God was able to be all of existence and yet create a existence outside of Himself through omnipotent active power. Even though there was no recipient of change but Him, was able to create a recipient.
Not all mysteries are explainable by human thought, once again observe the hierarchy of existence. Material causes, being an unconscious and unintelligible things, have no awareness of anything (itself or outside of itself). Inanimate things (like plants) have inherent powers of absorption of nutrient and reproduction, unintelligent of anything outside of itself. Animated things, like animals, have all properties of things below it and have a higher inherent power that of locomotion and sensation and aware of things outside of themselves but unintelligible of things are that are not inherently known to them. Human beings have all casual powers of physical existences plus intelligence and will, but unaware of the immaterial world and higher beings and the Pure Actual Being. Thus requiring a revelation to humans from the immaterial world in some form for humans to intellectually grasp, even though not fully, that world.
If we are unable to fully grasp the immaterial world, how do you think you’ll even grasp a fraction of God’s omnipotence, let alone His existence?
I don’t know why that’s hard to accept when free will is an even greater creation then that of potentiality outside of God. To think we are created and yet have powers of total free will is still beyond me.
