In Luther's eyes, "The Papists have made out of God a merchant, who would give the Kingdom of Heaven not freely, out of grace, but for money and human achievement." "Under the Papacy the Devil has established a market in souls," "The Papacy has made an annual market out of the Mass and out of forgiveness of sins."
