Moral character is assessed not by what a man knows but by what he loves - Augustine of Hippo

When I come across one or other of my fellow Christians ignorant of astronomy, believing what is not so, I calmly look on, not thinking him the worse for mistaking the place or order of created things, so long as he holds nothing demeaning to you, Lord, the creator of all those things. But he is worse off if he holds that his error is a matter of religious faith, and persists stubbornly in the error. His faith is still a weak thing in its cradle, needing the milk of a mothering love, until the youth grows up and cannot be the play-thing, any more, of every doctrinal wind that blows.

But one who ventures on the role of teacher, of leader and ruler of those under his spell, whose followers heed him not as a man only but as your very Spirit — what are we to make of him when he is caught purveying falsehoods? Should we not reject and despise such madness?

Quid est ira? Libido vindictae. Quid est odium? Ira inveterata.

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.
