Lord of the Church, we humbly pray. E. Osler. [Whitsuntide.] First published in Hall's Mitre Hymn Book, 1836, No. 219, in 3 stanzas of 6 lines, and again, with slight alterations, in the author's Church and King, April, 1837, p. 112. It is an altered version by Osler of Charles Wesley's "Thou, Jesu, Thou my breast inspire" (q.v.). Wesley's original text, however, is scarcely recognizable in the form given to it by Osler, save in the last six lines, which are almost entirely from Wesley. The Irish Church Hymnal follows the text of the Mitre. Its use is extensive.
