Fr. Fenton laments adiaphoronism on his blog. His comments reminded me of an interesting tidbit I came across in an old CTQ (62:2:140):
Bugenhagen, who prepared this rite, takes a much stricter line on liturgical non-deviation than Luther did: "this is an order, and is to be followed as closely as the old order was!"
This in regards to the Liturgy for Brunswick in 1528. Luther's orders were neither of them actually put into Church Law at the time of the Reformation, though they greatly influenced those that were. But each territory did promulgate a liturgical order that was "to be followed as closely as the old order was" - and thus the myth of Lutherans of the 16th century all doing their own thing parish by parish is false.
