This greatness both of God towards us, and of ourselves towards Him, we ought always as much as possible to retain in our understanding. And when we cannot effectually keep it alive in our senses, to cherish the memory of it in the centre of our hearts, and do all things in the power of it. For the Angels when they come to us, so fulfill their outward ministry, that within they nevertheless maintain the beatific vision ministering before the Throne of God, and among the sons of men at the same time. The reason where of St. Gregory with is this: The the Spirit of an Angel be limited and circumscribed in itself, yet the Supreme Spirit, which is God, is uncircumscribed. He is everywhere and wholly everywhere: which makes their knowledge to be dilated everywhere. For being wholly everywhere, they are immediately present with His omnipresence in everyplace and wholly. It filleth them for ever.
