THAT THESE WORDS OF CHRIST, “THIS IS MY BODY,” ETC., STILL STAND FIRM AGAINST THE FANATICS 1527

So I shall once more set myself against the devil and his fanatics, not for their sake, but for the sake of the weak and simple. For I have no hope that the teachers of a heresy or fanaticism will be converted. Indeed, if that were possible, so much has already been written that they would have been converted. It has never been reported that an author of false doctrine was converted. For this sin is too great, because it blasphemes God’s Word and sins against the Holy Spirit. Therefore God lets it become hardened, with the result, according to the word of Isaiah 6[9 f.], “With seeing eyes you shall not see and with hearing ears you shall not hear, for this people’s heart is hardened.” -Martin Luther
