My good buddy Sal wrote that he was a bit disappointed that the LCMS church he attended today did not celebrate the Presentation of the Augsburg Confession (and he went Slovak this Sunday, though he may not know it; I LOVE the Slovaks - I vicared for them). St. Paul's, Hamel, didn't either - following the new rubrics from Lutheran Service Book, where the Presentation of the Augsburg Confession has been moved to the commemorations and is not regarded as a feast or festival.
We had a visiting clergyman with us this weekend and he asked about our non-celebration too. I must confess, I think that the LSB is more in the spirit of the Augustana than the LW with its observation of the day. The whole point of the Augsburg Confession was to confess "nothing new." To celebrate a day for the "nothing new" confession would be okay, but far more persuasive would be to celebrate the day as what it was: the Second Sunday after Trinity. That's not to put down the Augsburg Confession, but to honor it for what it intended to be: not a charter for Lutheran Independence, but a call for genuine catholicity.
