“One of the most crushing indictments of Protestantism is that it has rejected the idea of the necessity of penance, and by doing so has out-dated and made meaningless large sections of the Bible. Probably no virtue is more insisted on in the Bible than the virtue of penance. "Unless you shall do penance, you shall all likewise perish." His Cross does not dispense us from the obligation of taking up our cross: "Unless a man take up his cross and follow Me, he cannot be My disciple." If Christ's sacrifice made further sacrifice unnecessary, the continuance of pain in the world presents more than a problem, in fact a contradiction.”
