Worthy the Lamb for sinners slain. [Praise to Jesus.] This cento appeared in the General Baptist New Hymn Book, edited by the brothers J. B. and J. C. Pike, in 1851; and was repeated in the Baptist Hymnal, 1879, in 5 stanzas of 4 lines. Of the cento stanzas i., ii. are from J. Montgomery's "Sing we the song of those who stand," and the rest (iii.-v.) are anonymous. The Rev. W. E. Stevenson, editor of the Baptist Hymnal, is strongly inclined to think that these stanzas were by the Rev. J. G. Pike, of Derby (with whom he was co-pastor for some time), who was the father of the brothers Pike named above: but he was not quite satisfied with his authority.
