From: The Catholic Encyclopedia, Vol. IX, 1910, Martin Luther.

It was while he [Martin Luther] was in these sinister moods that his friends usually were in expectant dread that the flood of his exhaustless abuse and unparalleled scurrility would dash itself against the papacy, Church, and monasticism. “I will curse and scold the scoundrels until I go to my grave, and never shall they hear a civil word from me. I will toll them to their graves with thunder and lightning. For I am unable to pray without at the same time cursing. If I am prompted to say: ‘hallowed be Thy name’, I must add: ‘cursed, damned, outraged be the name of the papists’. If I am prompted to say: ‘Thy Kingdom come’, I must perforce add: ‘cursed, damned, destroyed must be the papacy.’ Indeed I pray thus orally every day and in my heart without intermission” (Sammtl. W., XXV, 108). Need we be surprised that one of his old admirers, whose name figured with his on the original Bull of excommunication, concludes that Luther “with his shameless, ungovernable tongue, must have lapsed into insanity or been inspired by the Evil Spirit” (Pirkheimer, ap. *Döllinger, “Die Reformation”, Ratisbon, I, 1846-48).

What the Lord’s Prayer really says about FORGIVING. Jesus made it clear right after “Amen”: “IF YOU DON’T forgive…” vs. Luther’s Catechism: “God forgives WITHOUT CONDITION,” even “REVENGE!!!”
