After this the aria "Et in spiritum sanctum," in which the next dogmatic clauses are enshrined like relics in a casket, furnishes a beautiful decorative design on which the listener can repose his mind; and then comes the voluminous ecclesiastical fugue, Confiteor unum baptisma, leading, as through the door and world-wide spaces of the Catholic Church, to that veil which is not all darkness to the eye of faith.

The final chorale and fugue was an excellent example of togetherness on all fronts.
