 Staupitz was no Lutheran, but was thoroughly Catholic in matters of faith, especially as regards the freedom of the will, the meritoriousness of good works, and justification, which has been established by Paulus from the writings of Staupitz.However, Luther perceived his abjuration as a betrayal.In his last letter to Luther in 1524 Staupitz made it clear he was bitter about the direction of the Reformation and its seemingly willful destruction of the unity of the Christian Church.
