“Thus the quarrel that arose between Remus and Romulus demonstrated the division of the earthly city against itself; while the conflict between Cain and Abel displayed the hostility between the two cities themselves, the City of God and the city of men. Thus”
― Augustine of Hippo, City of God

“In this manner the Church proceeds on its pilgrim way in this world, in these evil days. Its troubled course began not merely in the time of the bodily presence of Christ and the time of his apostles; it started with Abel himself, the first righteous man slain by an ungodly brother; and the pilgrimage goes on from that time right up to the end of history, with the persecutions of the world on one side, and on the other the consolations of God.”
― Augustine of Hippo, City of God

“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.”
― Augustine of Hippo, City of God
