"Be a sinner and sin boldly, but believe and rejoice in Christ even more boldly, for he is victorious over sin, death, and the world. As long as we are here [in this world] we have to sin... No sin will separate us from the Lamb, even though we commit fornication and murder a thousand times a day."This quote is taken from a letter that Martin Luther wrote in 1521. Now in its 500th year, the protestant rebellion, which Luther initiated, destroyed Christendom and continues to divide the Body of Christ to this day. To commemorate this tragic event, we should reflect upon the prayer of Our Lord in the Gospel according to Saint John (17:11-23)
“Holy Father, keep them in thy name whom thou has given me; that they may be one, as we also are….Sanctify them in truth. Thy word is truth. As thou hast sent me into the world, I also have sent them into the world.  And for them do I sanctify myself, that they also may be sanctified in truth. And not for them only do I pray, but for them also who through their word shall believe in me;
“That they all may be one, as thou, Father, in me, and I in thee; that they also may be one in us; that the world may believe that thou hast sent me. And the glory which thou hast given me, I have given to them; that they may be one, as we also are one: I in them, and thou in me; that they may be made perfect in one: and the world may know that thou hast sent me, and hast loved them, as thou hast also loved me.”Here are a few more quotes from the heresiarch known as Martin Luther. May the errors of Luther be extirpated from among mankind. May his remaining followers find the truth, repent and accept again communion with the One Holy Catholic and Apostolic Church.
“To kill a peasant is not murder; it is helping to extinguish the conflagration. Let there be no half measures! Crush them! Cut their throats! Transfix them. Leave no stone unturned! To kill a peasant is to destroy a mad dog!” – “If they say that I am very hard and merciless, mercy be damned. Let whoever can stab, strangle, and kill them like mad dogs.”
“What harm could it do if a man told a good lusty lie in a worthy cause and for the sake of the Christian Churches?”
“If I had to baptize a Jew, I would take him to the bridge of the Elbe, hang a stone round his neck and push him over with the words I baptize thee in the name of Abraham.”
"Burn their synagogues. Forbid them all that I have mentioned above. Force them to work and treat them with every kind of severity, as Moses did in the desert and slew three thousand... If that is no use, we must drive them away like mad dogs, in order that we may not be partakers of their abominable blasphemy and of all their vices, and in order that we may not deserve the anger of God and be damned with them. I have done my duty. Let everyone see how he does his. I am excused."These quotes (plus many more) and their sources may be found here.
