“Fire and water are incompatible; and so is judging others in one who wants to repent. If you see someone falling into sin at the very moment of his death, even then do not judge him, because the Divine judgment is hidden from men. Some have fallen openly into great sins, but they have done greater good deeds in secret; so their critics were tricked, getting smoke instead of the sun.”
