God is in all things as that of a being of an agent, and not simply as a part of their essence or as an accident. By this “agent” we mean that God is the first act, and as such must be joined or present to the continuous movement of beings. If it is a being at all, it must be attached to it effect if it should continuously exist. Further, we can extrapolate that God must be everywhere, omnipresent.
The limitless cannot be limited, and the infinite cannot be finite. He is also everywhere in three ways: essence, presence, and power. Essence by agent of efficient cause, presence by perfect knowledge and infinite existence, power by creator of all things.
These are not accidents in other things and so he alone is not particular but universal in his infinity of presence and power.
To study the Summa Theologiae, I highly suggest doing so with Verbum from Logos bible software. Verbum is a state-of-the-art library that connects thousands of resources so that you can study a subject with layers of depth, analysis, and understanding. If you’re new to the Summa, you really need companion material and it’s all available in the Verbum package. For example, each Question and Article in the Summa sources several other documents of the Magisterium, other philosophers, Church Fathers, etc., – and Verbum connects them all, so that in one click, you can explore and connect the Tradition of the Church easily and scholarly. I use Verbum everyday, no exaggeration, it’s that important to me. Learn more about Verbum here.
