Think of the Father as a spring of life begetting the Son like a river and the Holy Ghost like a sea, for the spring and the river and sea are all one nature. Think of the Father as a root, and of the Son as a branch, and the Spirit as a fruit, for the substance in these three is one. The Father is a sun with the Son as rays and the Holy Ghost as heat.
John of DamascusAn angel is an intelligent essence, always in motion. It has free will, is incorporeal, serves God, and has been bestowed with immortality. Only the Creator understands its true nature.
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.
John of DamascusIn former times, God, who is without form or body, could never be depicted. But now when God is seen in the flesh conversing with men, I make an image of the God whom I see. I do not worship matter; I worship the Creator of matter who became matter for my sake.
John of DamascusAnd all that is therein; Invisible and visible, Their notes let all things blend, For Christ the Lord is risen. Our joy that hath no end.
