Walther was very interesting when he had guests at his table. ... I remember that one day Dr. Philip Schaff, the well-known church historian and Reformed theologian and founder of the American Society of Church History, at that time professor in Union Theological Seminary in New York, called on him. At the close of his [page 88] visit Walther showed him through our new Seminary building, and I had occasion to note that the conversation was quite animated. But also on such occasions Walther never failed to testify. I do not know what was under discussion, but I heard Walther say very emphatically: “Das lehren Sie eben nicht,” this you do not teach. And finally I saw that he escorted Dr. Schaff to the streetcar and very courteously bade him adieu.
"This you do not teach!"
The Lutheran Doctrine of JustificationThat is what all the Reformed DO NOT TEACH ==>> the pure, unconditional Gospel!
What does this mean? It means that all the "Church History", all 8 volumes of Schaff's massive work is suspect in its spiritual judgments. It means that Dr. Philip Schaff is NOT the best source of "Church History" because, as C.F.W. Walther put it to him, "This you do not teach".
And so all true Lutherans should bid "adieu" to the Reformed saying "You left your first love, the love of the Lutheran Church – the pure, unconditional Gospel... this you do not teach"
