They come, God's messengers of love. R. Campbell. [St. Michael and All Angels.] Written for, and first published in his Hymns and Anthems, 1850, p. 94, in 6 stanzas of 4 lines. In 1852 it was republished, with alterations, in Murray's Hymnal, No. 79. This was repeated in several collections, including Hymns Ancient & Modern, 1861, and has become the accepted form of the hymn. Sometimes it is abridged to four stanzas. It is the most widely adopted hymn for St. Michael and All Angels of any in the English language.
