LCMS Worship provides propers for commemorating the Presentation of the Augsburg Confession, which occurred on June 25, 1530.
The confession of faith was presented by Philipp Melancthon, who spoke on behalf of various German rulers and free cities to Holy Roman Emperor Charles V at the Diet of Augsburg.
Lutheran Service Book lists the Presentation of the Augsburg Confession as a commemoration and therefore provides no propers. Therefore, LCMS Worship suggests an Introit, Collect of the Day, Old Testament Reading, Psalm, Epistle, Verse, Holy Gospel, Hymn of the Day, and Preface.
