Coelitum Joseph decus. [St. Joseph .] This hymn for the Feast of St. Joseph, the husband of the Blessed Virgin Mary, which has been added to the Roman Breviary since 1632, is of unknown authorship. In addition to being in that Office, Daniel has reprinted it, iv. p. 296. Translated as:—
Joseph, our certain hope below, by E. Caswall, in his Masque of Mary, 1858, in 5 stanzas of 4 lines, and thence into his Hymns, &c, 1873, p. 74. This translation is in use in Roman Catholic hymnals for Schools and Missions.
Translation not in common use:--
O Joseph, glory of the heavenly choir. J. Wallace. 1874.
