Early in life Bryant came under the influence of the Unitarian doctrines which were then sweeping through New England as a reaction against the stern, harsh teachings of Puritanism. When he was only twenty-six years old he was invited to contribute to a volume of hymns then in course of preparation by the Unitarians. He responded by writing five hymns. Six years later he wrote “Thou, whose unmeasured temple stands” for the dedication of the Second Unitarian Church of New York City. He usually attended the First Congregational Unitarian Church of that city.
About thirty years later, however, when Bryant was sixty-four years old, a profound change occurred in his religious convictions. During a trip abroad his wife became critically ill in Naples. At first her life was despaired of, but when she finally was on the road to recovery Bryant sent for a warm friend of the family, Rev. R. C. Waterston, who was in Naples at the time. The latter tells of his meeting with the aged poet in the following words:
“On the following day, the weather being delightful, we walked in the royal park or garden overlooking the Bay of Naples. Never can I forget the beautiful spirit that breathed through every word he (Bryant) uttered, the reverent love, the confiding trust, the aspiring hope, the rooted faith.... He said that he had never united himself with the Church, which, with his present feeling, he would most gladly do. He then asked if it would be agreeable to me to come to his room on the morrow and administer the communion, adding that, as he had never been baptized, he desired that ordinance at the same time.
“The day following was the Sabbath, and a most heavenly day. In fulfilment of his wishes, in his own quiet room, a company of seven persons celebrated together the Lord’s Supper.... Previous to the breaking of bread, William Cullen Bryant was baptized. With snow-white head and flowing beard, he stood like one of the ancient prophets, and perhaps never, since the days of the apostles, has a truer disciple professed allegiance to the divine Master.”
Twenty years after this experience, in the last year of the poet’s life, he made some contributions to the Methodist Episcopal hymnal. A revision of one of the hymns which he had written in 1820 for the Unitarian hymnal reveals his changed attitude toward the Lord Jesus Christ. For the Unitarian book he had written:
Deem not that they are blest alone
Whose days a peaceful tenor keep;
The God who loves our race has shown
A blessing for the eyes that weep.
For the Methodist hymn-book he changed the third line to read:
