Bishop of Hippo Saint Augustine, The City of God, Volume I
“ This is the most glorious city of God; this is the city which knows and worships one God: she is celebrated by the holy angels, who invite us to their society, and desire us to become fellow-citizens with them in this city; for they do not wish us to worship them as our gods, but to join them in worshipping their God and ours; nor to sacrifice to them, but, together with them, to become a sacrifice to God. ”
