James Swan (of Beggars All Reformation) featured C. A. Piepkorn's take on Luther's alledged belief in the Immaculate Conception. Read James' post here.
At the tail end of that post, I was amazed with this little tidbit of information
Not that this has any bearing on Piepkorn's Mariological statements, but interestingly, Piepkorn was charged, convicted, and removed due to teaching false doctrine:
“During the mid-seventies amidst the storm of the Lutheran Church-Missouri Synod controversy, Piepkorn was among those of the faculty majority at Concordia Seminary, St. Louis, cited as teaching false doctrine by the 1973 New Orleans Convention resolution 3-09. Piepkorn was a signatory of the Seminary majority's protest against this resolution and resolution 3-01, which declared that all of the synod's theological and biblical interpretation and teachings must be interpreted in accord with a presumed synodical tradition as articulated in the document entitled, "A Statement of Scriptural and Confessional Principles," by Dr. Jacob A. 0. Preus, President of the Lutheran Church-Missouri Synod.” (Plekon and Wiecher, The Church: Selected Writings of Arthur Carl Piepkorn, New York: ALPB Books, 1993, 300.)
This is interesting for me because Piepkorn is usually the icon of those Augsburgians who are swimming the Tiber, e.g. Neuhaus etc.
