A thousand oracles divine. C. Wesley. [Holy Trinity .] In his Hymns on the Trinity, 1767, this hymn is given as No. xvii. in the division of "Hymns and Prayers to the Trinity” in 4 stanzas of 8 lines, p. 100. It was repeated in the Wesleyan Hymn Book 1780, and later editions with the simple alteration of "His hosts" to “the hosts" in stanza i. line 6. From that collection it has passed into all the principal hymnals of the Methodist bodies in most English-speaking countries, but is seldom found elsewhere. Few hymns are more dogmatic on the doctrine of the Trinity. The lines, "The Friend of earth-born man," and "For heaven's superior praise," are borrowed from Young's Night Thoughts . Night iv. 11. 603. 440. Original text as above, and Poetical Works of J. & C. Wesley, 1868-1872, vol. vii. pp. 312-13.
