“No one ought to be ashamed of becoming poor after being rich, if this happens because he gives freely to the poor; for Christ became poor when He was rich, that through His poverty He might enrich all. He has given us a rule to follow, so that we may give a good account of our reduced inheritance; whoever has stayed the hunger of the poor has lightened his distress.”
Ambrose of Milan (337-397) in On the Duties of Clergy 30.151.
