are four quasi-ostinato pedal statements of the first subject, recalling the stile antico pedal part of the first section. Above the pedal the third subject and its semiquaver countersubject are developed with increasing expansiveness and continuity. The penultimate entry of the first subject is a canon between the soaring treble part and the pedal, with descending semiquaver scales in the inner parts. There is a climactic point at bar 114—the second bar below—with the final resounding entry of the first subject in the pedal. It brings the work to its brilliant conclusion, with a unique combination of the backward looking stile antico in the pedal and the forward looking stile moderno in the upper parts.

The first Deutsche Messe in 1525 was held at Advent so did not contain the Gloria, explaining its absence in Luther's text the following year. Although there was a German version of the Gloria in the Naumburg hymnal, the 1523 hymn "Allein Gott in der Höh sei Ehr" of Nikolaus Decius, also adapted from plainchant, eventually became adopted almost universally throughout Germany: it first appeared in print with these words in the 1545 Magdeburg hymnal Kirchengesenge Deudsch of the reformist Johann Spangenberg. A century later, Lutheran liturgical texts and hymnody were in wide circulation. In Leipzig, Bach had at his disposal the Neu Leipziger gesangbuch (1682) of Gottfried Vopelius. Luther was a firm advocate of the use of the arts, particularly music, in worship. He sang in the choir of the Georgenkirche in Eisenach, where Bach's uncle Johann Christoph Bach
