O Jesus! God and man. F. W. Faber. [Children's Hymn.] This popular children's hymn was given in his Jesus and Mary, &c, 1849, in 7 stanzas of 4 lines, and headed "Ragged School Hymn." In common use it is found in two forms, first, the original, in Roman Catholic hymnbooks for missions and schools, in which stanzas iii., iv., both of which are addressed to the Blessed Virgin Mary are retained; and second, in other hymnbooks, where they are omitted. Original text in Faber's Hymns, 1862.
