DEUS TUORUM MILITUM (sometimes called GRENOBLE) was published in France in the 1753 Grenoble Antiphoner as a setting for the text "Deus tuorum militum" (“The God of Your Soldiers”). One of the finest French diocesan tunes from the eighteenth century, it represents a departure in Roman Catholic hymnody from the older chant style. Sing with vigor.
