Your church and adherents have a great disdain for Martin Luther. Other than the nail marks to a church door, what are your grievances against him? He tried to correct wrongs in the church. He read the Bible. He prayed. The contradictions were self evident. The sale of indulgences were the result of avarice not soul saving. He was sad that the Church he loved had strayed so far from its purpose.
1) Martin Luther was not infallible.
2) His doctrine of “the Bible alone,” as the sole rule of faith, isn’t in the Bible.
Therefore, Protestantism has no logical basis.
This is why Catholics aren’t interested in Protestantism.
We are interested in an infallible teaching Authority, “the pillar and foundation of truth,” the Church of Christ, the Catholic Church.
That is not a grievance at all. His 90 (or whatever the number) theses were all questions worth discussing and posting a proposal for a debate on the doors of a church was accepted practice at the time.
The grievance against Luther is that he promulgated unbiblical theological fantasies of Sola Scriptura and Sola Fide, tossed from the Old Testament books he found inconvenient for himself, desecrated monasteries, started a new iconoclasm, and lead millions away from Christ. Since Mohammed, there was no greater enemy of Christ than Martin Luther.
