“”I don’t see the part where Luther states the Reformation was a mistake””
Perhaps you should read more on Luther ,dear friend.
Like this...
“We concede — as we must — that so much of what they [the Catholic Church] say 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 St. John, chaps. 14 - 16 (1537), in vol. 24 of LUTHER’S WORKS, St. Louis, Mo.: Concordia, 1961, 304.
“”The ‘errors’ referenced have been around since the beginning.””
You’re correct,but now these errors and many others are rampant now further dividing Christianity into a religion of pluralism with no unity.
The Catholic Church is the only source of Concrete dogmatic teachings,like it or not,protestantism only holds to some of these concrete teachings because the Catholic Church made them concrete and unchangeable because Our Blessed Lord gave them to the Church. Read the quote I gave you from Luther again,he even admitted it
Thank God Luther is not our pope.. or we would have to agree with him :)
No doubt, Luther was a Catholic. No surprise here. Lutherans (including Luther) don't say the (Roman) Catholic Church is errant on all points of doctrine, just some. Where (R) Catholicism makes it dogma or doctrine and is errant, the Lutherans will object as did Luther. Luther wanted to reform the Catholic Church and bring it back to its roots hence the term Reformation. As other Catholics including yourself have noted, there were changes that needed to be made that the Catholic Church did make. However the errors continue to day on a number of subjects. viv a vis Lutherans and Catholics.
Lutherans today are not bound to Luther's personal views

I must gently call cow splat. God made them concrete and unchangeable, not Catholics and He did give them to His Church, the one comprising all He calls via the Holy Spirit.
