The devotional spirit of Unitarians, however, has found its most emphatic and beautiful expression in religious hymns and poems. The older Unitarian piety found voice in the hymns of the younger Henry Ware, Norton, Pierpont, Frothingham, Peabody, Lunt, Bryant, and many others. It was rational and yet Christian, simple in sentiment and yet it found in the New Testament traditions its themes and its symbolisms. Then followed the older transcendentalists, who sought in the inward life and the soul's oneness with God the chief motives to spiritual expression. The hymns and the religious poems of Furness, Hedge, Longfellow, Johnson, Clarke, Very, Brooks, and Miss Scudder,[13] have an interior and spiritual quality seldom found in devotional poetry. They are not the mere utterances of conventional sentiments or the repetition of ecclesiastical symbolisms, but the voicing of deep inward experiences that reveal and interpret the true life of the soul. Of the same character are the hymns and religious poems of Gannett, Hosmer, and Chadwick, who have but accentuated the tendencies of their predecessors. It is the more radical theology that has voiced itself in the religious songs of these men, but with a mystical or spiritual insight that fits them to the needs of all devout, worshippers. It is these genuinely poetical interpretations of the spiritual life that most often claim utterance in song on the part of Unitarian congregations. A body of worshippers that can produce such a hymnology must possess a large measure of genuine piety and devotion. [Sidenote: The Seventy-fifth Anniversary.] Many of the tendencies of the Unitarian movement found utterance on the occasion of the seventy-fifth anniversary of the American Unitarian Association. The meetings were held in Tremont Temple, May 22, 1900; and the attendance was large and enthusiastic, many persons coming from distant parts of the country. This meeting brought into full expression the denominational consciousness, and showed the harmony that had been secured as the result of the controversies of many years. As never before, it was realized that the Unitarian body has a distinct mission, that it has organic and vital power, and that its individual members are united by a common faith for the promotion of the interests of a rational and humanitarian religion. This was also a notable occasion because it brought together representatives from nearly all the countries in which Unitarianism exists in an organized form, thus clearly indicating that it is a cosmopolitan movement, and not one of merely local significance. At the morning session addresses were made by the representatives from Hungary, Great Britain, Germany, Belgium, India, and Japan. In the afternoon addresses were delivered by the missionaries of the Association. Other meetings of much interest were held during the week, that were of value as interpretations of the past of Unitarianism in this country.
