A quick look at some hymns by Martin Franzmann will reveal that he lived up to this edict.
What we sing matters. What we sing teaches us about our faith. Whether we sing, "I Am Jesus' Little Lamb" or "At the Lamb's High Feast We Sing," we are proclaiming in song that which we believe; we are proclaiming that which the church has taught from the beginning. When choosing music for worship, one must ask, "Is this hymn proclaiming that which has been taught throughout the ages? Is our liturgy in line with those who have gone before?"
The Lutheran Reformation was not about uncovering something new, rather it was about restoring the historic teachings of the church. The Confessions and other writings of the Lutheran reformers are filled with references not only to Scripture, but also to the Church Fathers, showing continuity between the first Christians and those of the present day. As Lutheran Christians, we do not have a faith that dates back to 1517, but rather a faith that dates back to the ancient church, to the apostles, and to the forerunners of Christianity: the great prophets who foretold of the coming Messiah and all those who trusted in this promise.
