All ye who faithful servants are. Tate & Brady. [Holy Communion.] This is Hymn ii. of the three hymns for Holy Communion which were given in the Supplement to the New Version, 1699. It is based on Rev. xix., and is in 4 stanzas of 4 lines. It is found in a few modern hymnals only, including Kennedy, 1863, No. 646, and the Sarum, 1868, No. 225, in both of which the changes in st. iv. of 1. 1, "bless'd" to "blest," and 1. 4, "Is call'd" to "Is made a welcome guest," are given. The text is otherwise correct.
