For all Thy saints, O Lord [God]. Bp. R. Mant. [All Saints.] An original hymn given with his translations in his Ancient Hymns, &c, 1837, p. 80 (edition 1871, p. 139), in 6 stanzas of 4 lines, and entitled, "Hymn on All Saints." The form in which it usually appears, in 4 stanzas, was given in the Society for Promoting Christian Knowledge Hymns, &c, 1852. In addition the following arrangements are also in common use:—
1. For Thy dear saint, O Lord. This was given in Hymns Ancient & Modern, 1861, No. 273. It is composed of stanzas i.-iii., v., of Bishop Mant's hymn, but considerably altered, and the substitution of another doxology.
2. For Thy true servants, Lord. This text in the Toronto Church Hymn Book, 1862, is the Hymns Ancient & Modern text slightly altered.
3. For this, Thy saint, O Lord. Another altered text in Skinner's Daily Service Hymnal, 1864.
Of these arrangements, the S P.C.K. is most popular, both in Great Britain and America. It sometimes reads, "For all Thy saints, O God.”
