As is well known, The Lutheran Church—Missouri Synod today teaches that it is at the very least permitted for Lutherans to pray with the Reformed and Papists. In 2015, President Matthew Harrison asserted on Issues, Etc.:
It’s always been the case from the earliest times of the Lutheran Church that we, at the Colloquy of Thorn, for instance, and in other instances, Reformed, Catholic, and Lutherans came together and they held prayers before sessions, praying for unity. I think that is certainly not inappropriate. It’s when Christians of differing confessions of faith are being absolutely transparent about the differences that they have.
Now, however, this is actually a blatant falsification of history. Harrison actually dares to bring the Colloquy of Thorn as an example of Lutherans practicing prayer fellowship with the sects! However, in the Calvinist Krasinski’s History of the Reformation in Poland, vol. 2, we read in chapter XI:
At the general meeting on the 16th of September, the confessions could not agree about the prayer with which every meeting was to commence. The Roman Catholics wished that the bishop of Samogitia should read at the opening of the meetings a prayer, containing nothing contrary to the doctrine of the other confessions, and that all present should repeat it. The Helvetians and Bohemians agreed to this proposition, but the Lutherans refused to join in prayer with persons from whom they differed in creed.
Now, surely the historians of the LCMS, in order that their unionistic spirit may be defended by any means available, will declare this to be a spurious report. But Krasinski surely would have little motive to falsify a report. Furthermore, L. Fuerbringer himself quoted this exact passage in the Lutheraner, 64, p. 111, presenting it as proof, as indeed it was, “that our fathers acted just as we do.”
