How precious the gift of the cross, how splendid to contemplate! In the cross there is no mingling of good and evil, as in the tree of paradise: it is wholly beautiful to behold and good to taste. The fruit of this tree is not death but life, not darkness but light. This tree does not cast us out of paradise, but opens the way for our return… A tree once caused our death, but now a tree brings life. Once deceived by a tree, we have now repelled the cunning serpent by a tree. What an astonishing transformation! That death should become life, that decay should become immortality, that shame should become glory!
–Saint Theodore the Studite (c. 759-826)
