2. The faculty of knowledge does not know anything actually without some attention and advertence. Hence the phantasms, stored in the sensorium, are at times not actually in the imagination, because no attention is given to them. We do not discern together a multitude of things to which we do not attend together: but things that necessarily fall under one and the same advertence and attention, are necessarily understood together. Thus whoever institutes a comparison of two things, directs his attention to both and discerns both together. But all things that are in the divine knowledge must necessarily fall under one advertence; for God is attentive to behold His essence perfectly, which is to see it to the whole reach of its virtual content, which includes all things. God therefore, in beholding His essence, discerns at once all things that are.
6. Every mind that understands one thing after another, is sometimes potentially intelligent, sometimes actually so; for while it understands the first thing actually, it understands the second potentially. But the divine mind is never potentially intelligent, but always actually: it does not, then, understand things in succession, but all at once.
Holy Scripture witnesses to this truth, saying that with God there is no change nor shadow of vicissitude (James i, 17).
1.54 : That the Divine Essence, being One, is the proper Likeness and Type of all things Intelligible
1.56 : That there is not Habitual Knowledge in God
