Channing was not alone in accepting Christianity as a spiritual principle that is natural and universal. As early as 1826 Alvan Lamson had defended the proposition that miracles are merely local in their nature, and that attention should be chiefly given to the tendency, spirit, and object of Christianity. He claimed that it bore on the face of it the marks of its heavenly origin, and that, when these are fully accepted, no other form of evidence is required.[[7]] In 1834 James Walker, in writing on The Philosophy of Man's Spiritual Nature in regard to the Foundations of Faith, had taken what was essentially the transcendentalist view of the origin and nature of religion. He contended for the "religion in the soul" that is authenticated "by the revelations of consciousness."[[8]] In 1836 Convers Francis, in, describing the religion of Christ as a purely internal principle, maintained the "quiet, spirit-searching character of Christianity," as "a kingdom wholly within the soul of man."[[9]]

When Convers Francis became a professor in the Harvard Divinity School, in 1842, the spiritual philosophy had recognition there; and he had a considerable influence upon the young men who came under his guidance. Though of the older way of thinking, George R. Noyes, who became a professor in the school in 1840, was always on the side of liberty of interpretation and expression. For the next two decades the Divinity School sent out a succession of such men as John Weiss, Octavius B. Frothingham, Samuel Longfellow, William J. Potter, and Francis E. Abbot, who were joined by William Henry Channing, Samuel Johnson, David A. Wasson, and others, who did not study there. These men gave a new meaning to Unitarianism, took it away from miracles to nature, discarded its evidences to rely on intuition, rejected its supernatural deity for an immanent God who speaks through all life his divine word.

During the interval between the New York convention and the first session of the National Conference, which was held in Syracuse, October 10-11, 1866, the questions which separated the conservatives and radicals were freely debated in the periodicals of the denomination, and also in sermons and pamphlets. The radicals organized for securing a revision of the constitution; and on the morning of the first day Francis E. Abbot, then the minister at Dover, N.H., offered a new preamble and first article as substitutes for those adopted in New York, in which he stated that "the object of Christianity is the universal diffusion of love, righteousness, and truth," that "perfect freedom of thought, which is at once the right and duty of every human being, always leads to diversity of opinion, and is therefore hindered by common creeds or statements of faith," and that therefore the churches assembled in the conference, "disregarding all sectarian or theological differences, and offering a cordial fellowship to all who will join them in Christian work, unite themselves in a common body, to be known as The National Conference of Unitarian and Independent Churches."

At the afternoon session Mr. Abbot's amendment was rejected; but on the motion of James Freeman Clarke the name was changed to The National Conference of Unitarian and Other Christian Churches. A resolution stating that the expression "Other Christian Churches was not meant to exclude religious societies which have no distinctive church organization, and are not nominally Christian, if they desire to co-operate with the Conference in what it regards as Christian work," was laid on the table.

Organization of the Free Religious Association.

The result of the refusal at Syracuse to revise the constitution of the National Conference was that the radical men on the railroad train returning to Boston held a consultation, and resolved to organize an association that would secure them the liberty they desired. After correspondence and much planning a meeting was held in Boston, at the house of Rev. Cyrus A. Bartol, on February 5, 1867, to consider what should be done. After a thorough discussion of the subject the Free Religious Association was planned; and the organization was perfected at a meeting held in Horticultural Hall, Boston, May 30, 1867. Some of those who took part in this movement thought that all religion had been outgrown, but the majority believed that it is essential and eternal. What they sought was to remove its local and national elements, and to get rid of its merely sectarian and traditional features.

At the first meeting the speakers were O.B. Frothingham, Henry Blanchard, Lucretia Mott, Robert Dale Owen, John Weiss, Oliver Johnson, Francis E. Abbot, David A. Wasson, T.W. Higginson, and R.W. Emerson; and discussion was participated in by A.B. Alcott, E.C. Towne, Frank B. Sanborn, Hannah E. Stevenson, Ednah D. Cheney, Charles C. Burleigh, and Caroline H. Dall. Of these persons, one-half had been Unitarian ministers, and about one-third of them were still settled over Unitarian parishes. Mr. Frothingham was elected president of the new organization, and Rev. William J. Potter secretary. The purposes of the Association were "to promote the interests of pure religion, to encourage the scientific study of theology and to increase fellowship in the spirit." In 1872 the constitution was revised by changing the subject of study from theology to man's religious nature and history, and by the addition of the statement that "nothing in the name or constitution of the Association shall ever be construed as limiting membership by any test of speculative opinion or belief,--or as defining the position of the Association, collectively considered, with reference to any such opinion or belief,--or as interfering in any other way with that absolute freedom of thought and expression which is the natural right of every rational being."

The original purpose of the Free Religious Association, as defined in its constitution and in the addresses delivered before it, was the recognition of the universality of religion, and the representation of all phases of religious opinion in its membership and on its platform. The circumstances of its organization, however, in some measure took it away from this broader position, and made it the organ of the radical Unitarian opinion. Those Unitarians who did not find in the American Unitarian Association and the National Conference such fellowship as they desired became active in the Free Religious organization.

The cause of Free Religion was ably presented in the pages of The Radical, a monthly journal edited by Sidney H. Morse, and published in Boston, and The Index, edited by Francis E. Abbot, at first in Toledo and then in Boston. It also found expression at the Sunday afternoon meetings held in Horticultural Hall, Boston, for several winters, beginning in 1868-69; in the conventions held in several of the leading cities of the northern states; at the gatherings of the Chestnut Street Club; and in the annual meetings of the Free Religious Association held in Boston during anniversary week. Little effort was made to organize churches, and only two or three came into existence distinctly on the basis of Free Religion. In connection with The Index, Francis E. Abbot organized the Liberal League to promote the interests of Free Religion, with about four hundred local branches; but this organization proved ineffective, and soon ceased its existence.

The withdrawal of the radicals into the Free Religious Association did not quiet the agitation in the Unitarian ranks, partly because some of the most active workers in that Association continued to occupy Unitarian pulpits, and partly because a considerable radical element did not withdraw in any manner. The conferences had an unfailing subject for exciting discussion, and the Unitarian body was at this time in a chronic condition of agitation. As in the days of the controversy about the Trinity, the more conservative ministers would not exchange pulpits with the more radical.
