here is what Luther admitted,
“We concede–as we must--that so much of what they [the Catholic Church] is true: that **the papacy has God’s word **and the office of the apostles, and that **we have received Holy Scriptures, **Baptism, the Sacrament, and the pulpit from them. What would we know of these if it were not for them?” (Sermon on the Gospel of John, chaps. 14-16 (1537), in vol. 24 of Luther’s Works, [St. Louis, Mo.: Concordia, 1961], p. 304).”
This ALSO demonstrates IMV, Luther knew and intended to do what he did and remain in what he did.
that’s my :twocents:
