All we know if an angel is that it is incorporeal, immaterial, and only by comparing it with God-who is incomparable-can we see that it has some density and body after all, since in reality only God is truly immaterial and incorporeal.
John of DamascusO Mother of God! If I place my confidence in thee, I shall be saved; if I am under thy protection, I have nothing to fear; for the fact of being thy client is a possession of a certainty of salvation which God grants only to those whom He intends to save.
John of DamascusI do not worship matter, I worship the God of matter, who became matter for my sake and deigned to inhabit matter, who worked out my salvation through matter. I will not cease from honoring that matter which works for my salvation. I venerate it, though not as God.
John of DamascusWater is also one of the four elements, the most beautiful of God's creations. It is both wet and cold, heavy, and with a tendency to descend, and flows with great readiness. It is this the Holy Scripture has in view when it says, "And the darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters." Water, then, is the most beautiful element and rich in usefulness, and purifies from all filth, and not only from the filth of the body but from that of the soul, if it should have received the grace of the Spirit.
