This succession of Unitarian hymn writers over a period of approximately 150 years can best be traced in the nearly 50 hymn books compiled by individuals or committees for use in Unitarian churches.[3] The editors of these books were among the best educated men of their time, who knew where to look for fresh lyrical utterances of a living faith. The earliest of them lived in the period when the traditional metrical psalms which, for more than two centuries, had been almost the only worship-song of the English speaking world, were being slowly superseded by the songs of a new age. These songs they chiefly found in the various hymn-books published for use in English Non-conformist chapels when the Church of England still generally adhered to the Old or New Versions of the Psalms. It was from these sources that Jeremy Belknap first introduced to Americans the hymns of Anne Steele, and included in his _Sacred Poetry_ (1795) hymns by Addison, Cowper, Newton, Doddridge and other English contemporaries. When, in 1808, the vestry of Trinity Church, Boston, impatient at the delay of the General Convention of the Protestant Episcopal Church in getting out a hymnal, issued one for their own use, they drew heavily upon Belknap’s collection, saying in their preface “In this selection we are chiefly indebted to Dr. Belknap, whose book unquestionably contains the best expressions of sacred poetry extant.” Many of the later collections in this series of Unitarian hymn books have been no less notable for their introduction to use in this country of new English hymns, such as Pope’s “Father of all, in every age;” Sir Walter Scott’s “When Israel of the Lord beloved;” translations of hymns in the Roman Breviary; Sarah Flower Adams’ “Nearer, my God, to Thee” (only three years after its publication in England); and Newman’s “Lead, kindly Light;” and for the ability of their compilers to discover fresh materials near at hand, as when Samuel Longfellow and Samuel Johnson were the first to notice the hymnic possibilities of Whittier’s poems. The story of American Unitarian hymnody begins with the publication in 1783 of the _Collection of Hymns—designed for the use of the West Society of Boston._ This church belonged to the liberal wing of New England Congregationalism, destined to become known as Unitarian a generation later. The book contained a small selection of traditional psalms and hymns by British authors and a number of quaintly didactic moral ditties in doggerel, presumably contributed by Boston versifiers who cannot now be identified.
