That the breach was inevitable seems to be the verdict of history; and yet it is not difficult to see to-day how it might have been avoided. The Unitarians were dealt with in such a manner that they could not continue the old connection without great discomfort and loss of self-respect. They were forced to organize for self-protection, and yet they did so reluctantly and with much misgiving. They would have preferred to remain as members of the united Congregational body, but the theological temper of the time made this impossible. It would not be just to say that there was actual persecution, but there could not be unity where there was not community of thought and faith.
When the division in the Congregational churches came, one hundred and twenty-five churches allied themselves with the Unitarians,--one hundred in Massachusetts, a score in other parts of New England, and a half-dozen west of the Hudson River. These churches numbered among them, however, many of the oldest and the strongest, including about twenty of the first twenty-five organized in Massachusetts, and among them Plymouth (organized in Scrooby), Salem, Dorchester, Boston, Watertown, Roxbury, Hingham, Concord, and Quincy. The ten Congregational churches in Boston, with the exception of the Old South, allied themselves with the Unitarians. Other first churches to take this action were those of Portsmouth, Kennebunk, and Portland.
Outside New England a beginning was made almost as soon as the Unitarian name came into recognition. At Charleston, S.C., the Congregational church, which had been very liberal, was divided in 1816 as the result of the preaching of Rev. Anthony Forster. He was led to read the works of Dr. Priestley, and became a Unitarian in consequence. Owing to ill-health, he was soon obliged to resign; and Rev. Samuel Gilman was installed in 1819. Rev. Robert Little, an English Unitarian, took up his residence in Washington in 1819, and began to preach there; and a church was organized in 1821. While chaplain of the House of Representatives, in 1821-22, Jared Sparks preached to this society fortnightly, and in the House Chamber on the alternate Sunday. When he went to Charleston, in 1819, to assist in the installation of Mr. Gilman, he preached to a very large congregation in the state-house in Raleigh; and the next year he spoke to large congregations in Virginia.[21] More than a decade earlier there were individual Unitarians in Kentucky.[22] On his journey to the ordination of Jared Sparks, Dr. Channing preached in a New York parlor; and on his return he occupied the lecture-hall of the Medical School. The result was the First Congregational Church (All Souls'), organized in 1819, which was followed by the Church of the Messiah in 1825. In fact, many of the more intelligent and thoughtful persons everywhere were inclined to accept a liberal interpretation of Christianity.
