St. John of Damascus on the Holy Icons
In times past, God, without body and form, could in no way be represented. But now, since God has appeared in the flesh and lived among men, I can depict that which is visible of God….[for Christ is "the image of the invisible God. (Col. 1:15.)] I do not venerate the matter but I venerate the Creator of matter, Who became matter for me, Who condescended to live in matter, and Who, through matter accomplished my salvation; I do not cease to respect the matter through which my salvation is accomplished.
