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 DamascusChrist sits in the body at the right hand of God the Father, but we do not hold that the right hand of the Father is actual place. For how could He that is uncircumscribed have a right hand limited by place? But we understand the right hand of the Father to be the glory and honor of the Godhead in which the Son of God, Who existed as God before the ages, and is of like essence to the Father, and in the end became flesh, has a seat in the body, His flesh sharing in the glory. For He along with His flesh is adored with one adoration by all creation.
John of DamascusThe whole earth is a living icon of the face of God. ... I do not worship matter. I worship the Creator of matter who became matter for my sake, who willed to take His abode in matter, who worked out my salvation through matter. Never will I cease honoring the matter which wrought my salvation! I honor it, but not as God. Because of this I salute all remaining matter with reverence, because God has filled it with his grace and power. Through it my salvation has come to me.
John of Damascus...we shall incur no slight injury, but rather great danger, if we rashly yield ourselves to the inclinations of men who aim at exciting strife and tumults, so as to draw us away from what is good? Let us cleave, therefore, to those who cultivate peace with godliness?
John of DamascusBecause the one who by excellency of nature transcends all quantity and size and magnitude...has now...contracted himself into a quantity and size and has acquired a physical identity, do not hesitate any longer to draw pictures and to set forth, for all to see, him who has chosen to let himself be seen.
