The earthly [city] has made for herself, according to her heart's desire, false gods out of any sources at all, even out of human beings, that she might adore them with sacrifices. The heavenly one, on the other hand, living like a wayfarer in this world, makes no false gods for herself. On the contrary, she herself is made by the true God that she may be herself a true sacrifice to Him.
