Ein feste Burg ist unser Gott
Starting in 1523, Martin Luther began translating worship texts into German from the Latin. He composed melodies for some hymns himself, such as "Ein feste Burg ist unser Gott" ("A Mighty Fortress Is Our God"), and even a few harmonized settings. For other hymns he adapted Gregorian chant melodies used in Catholic worship to fit new German texts, sometimes using the same melody more than once. For example, he fitted the melody of the hymn "Veni redemptor gentium" to three different texts, "Verleih uns Frieden gnädiglich", "Erhalt uns, Herr, bei deinem Wort", and "Nun komm, der Heiden Heiland". The first Lutheran hymns were published in 1524. These included the ' (known as the first Lutheran hymnal) and the "Erfurt Enchiridion" (both with unaccompanied melodic settings), as well as Johann Walter's ', the first to contain part song settings of Lutheran hymns.
