[The Holy Spirit] is present as a whole to each and wholly present everywhere. He is portioned out impassably and participated in as a whole. He is like a sunbeam whose grace is present to the one who enjoys him as if he were present to such a one alone, and still he illuminates land and sea and is mixed with the air. Just so, indeed, the Spirit is present to each one who is fit to receive him, as if he were present to him alone, and still he sends out his grace that is complete and sufficient for all. The things that participate in him enjoy him to the extent that their nature allows, not to the extent that his power allows.
