Nicolaus Copernicus, a Polish astronomer, was the one who said the earth revolved around the sun, not vice versa. As revolutionary as the thoughts of Copernicus were in science, his thoughts about mercy and forgiveness were no less profound: "I do not ask the grace which thou didst give to St. Paul; nor can I dare to ask the grace which thou didst grant to St. Peter; but, the mercy which thou didst show to the dying robber, that mercy, show to me."
