"Sonne der Gerechtigkeit" is a German Christian hymn with a complex history. The image of a sun of justice or righteousness was created by the prophet Malachi. The text was compiled around 1930 by Otto Riethmüller from older stanzas by different hymnwriters, intended as a wake-up call to the church in a Germany facing the rise of the Nazis. Four of its originally seven stanzas were written in the 18th century, two by Johann Christian Nehring, and two by Christian David. The remaining stanzas were taken from Christian Gottlob Barth, written in the 19th century. An alternative seventh stanza was suggested in 1970, with a strong ecumenical focus. The hymn expresses a call for justice, renewal and unity, within the congregation and church, and among peoples.

Gotteslob is the title of the hymnbook authorized by the Catholic dioceses in Germany, Austria, South Tyrol, Luxembourg and Liège, Belgium. First published in Advent 2013, it is the current official hymnal for German-speaking Catholics, succeeding the first common German hymnal, the 1975 edition of the same name. Each diocese published a book containing a common section and a regional section. The first editions amounted to around 4 million copies.
