The Enchiridion

Those, then, who think that they can by giving alms, however profuse, whether in money or in kind, purchase for themselves the privilege of persisting with impunity in their monstrous crimes and hideous vices, need not thus deceive themselves. For not only do they commit these sins, but they love them so much that they would like to go on forever committing them, if only they could do so with impunity. Now, he who loves iniquity hates his own soul; and he who hates his own soul is not merciful but cruel towards it. For in loving it according to the world, he hates it according to God. But if he desired to give alms to it which should make all things clean unto him, he would hate it according to the world, and love it according to God. Now no one gives alms unless he receive what he gives from one who is not in want of it. Therefore it is said, “His mercy shall meet me.”
