"No one becomes depraved all at once."

Next Quote

Now although man is created for the possession of happiness, yet, having deviated from his true end, his nature has become deformed and is entirely repugnant to true beatitude. And on this account we are forced to submit to God this depraved nature of ours which fills our understanding with so many occupations, and causes us to deviate from the true path, in order that he may entirely consume it until nothing remains there but himself; otherwise the soul could never attain stability nor repose, for she was created for no other end.

— Catherine of Genoa
