Two months ago, on February 22, a Lutheran pastor and his wife, both faithful and fruitful servants of our Lord, began their personal celebration of "the feast of victory for our God." They now chant with the saints and all the heavenly host. "Worthy is Christ the Lamb who was slain, whose blood set us free to be people of God." It would only be just if the choir director had chosen that hymn of praise to be sung by the choir that day, because the two I speak of were the Rev. Herbert and Ruth Undemann. Pastor Undemann left at least two great monuments to his passion for his Lord, this Institute of Liturgical Studies and the Lutheran Book of Worship. They also left us memories of a gracious, cultured way of life controlled by an abiding love of the Church and her worship.
