Context

“Whether the Angel Obtained Beatitude Immediately After One Act of Merit? Objection 1: It would seem that the angel did not possess beatitude instantly after one act of merit. For it is more difficult for a man to do well than for an angel. But man is not rewarded at once after one act of merit. Therefore neither was the angel. Obj. 2: Further, an angel could act at once, and in an instant, from the very outset of his creation, for even natural bodies begin to be moved in the very instant of their creation;” source
