“It is from deep conviction that I have stated once and again that the differences between Unitarians and Trinitarians lie more in sounds than in ideas; that a barbarous phraseology is the chief wall of partition between these classes of Christians; and that could Trinitarians tell us what they mean, their system would generally be found little else than a mystical form of the Unitarian doctrine.”

Calvinists could not be blamed for thinking that their venerable creed, the painful outcome of the closest and most strenuous reasoning known in the Christian world, was entitled to more respect than to be called “little else than a mystical form of the Unitarian doctrine.” The Unitarians themselves scarcely attempted to make the infinite more intelligible to the finite by any new phraseology. They avowed a dislike for dogma as their merit. During these early years they systematically avoided controversy; in the pulpit they never assailed and seldom mentioned other forms of Christian faith, or even the scheme of Trinity which caused their schism.

“So deeply are we convinced,” said Channing’s letter, “that the great end of preaching is to promote a spirit of love, a sober, righteous, and godly life, and that every doctrine is to be urged simply and exclusively for this end, that we have sacrificed our ease, and have chosen to be less striking preachers rather than to enter the lists of controversy.”

Yet the popular dislike of Calvinistic severity could not wholly make good the want of doctrinal theology. The Unitarian clergy, however unwilling to widen the breach between themselves and the old Church, were ill at ease under the challenges of Orthodox critics, and could not escape the necessity of defining their belief.

“According to your own concession,” rejoined Dr. Samuel Worcester to Channing’s letter, “the party in whose behalf you plead generally deny the essential divinity of the Saviour, and hold him to be a being entirely ‘distinct from God,’ entirely ‘dependent,’—in other words, a mere creature.... You doubtless do not suppose that by any mere creature atonement could be made for the sins of an apostate world of sufficient merit for the pardon, sanctification, and eternal salvation of all who should trust in him; therefore if you hold to atonement in any sense, yet unquestionably not in the sense of a proper propitiatory sacrifice. Upon this denial of atonement must follow of course the denial of pardon procured by the blood of Christ, of justification through faith in him, of redemption from eternal death unto everlasting life by him. Connected, and generally if not invariably concomitant, with the denial of these doctrines is a denial of the Holy Spirit in his personal character and offices, and of the renewal of mankind unto holiness by his sovereign agency, as held by Orthodox Christians. Now, sir, are these small and trivial points of difference between you and us?”

Channing protested against these inferences; but he did not deny—indeed, he affirmed—that Unitarians regarded dogma as unnecessary to salvation. “In our judgment of professed Christians,” he replied, “we are guided more by their temper and lives than by any peculiarities of opinion. We lay it down as a great and indisputable opinion, clear as the sun at noonday, that the great end for which Christian truth is revealed is the sanctification of the soul, the formation of the Christian character; and wherever we see the marks of this character displayed in a professed disciple of Jesus, we hope, and rejoice to hope, that he has received all the truth which is necessary to his salvation.” The hope might help to soothe anxiety and distress, but it defied conclusions reached by the most anxious and often renewed labors of churchmen for eighteen hundred years. Something more than a hope was necessary as the foundation of a faith.

Not until the year 1819, did Channing quit the cautious attitude he at first assumed. Then, in his “Sermon on the Ordination of Jared Sparks” at Baltimore, he accepted the obligation to define his relation to Christian doctrine, and with the support of Andrews Norton, Henry Ware, and other Unitarian clergymen gave a doctrinal character to the movement. With this phase of his influence the present story has nothing to do. In the intellectual development of the country, the earlier stage of Unitarianism was more interesting than the later, for it marked a general tendency of national thought. At a time when Boston grew little in population and but moderately in wealth, and when it was regarded with antipathy, both political and religious, by a vast majority of the American people, its society had never been so agreeable or so fecund. No such display of fresh and winning genius had yet been seen in America as was offered by the genial outburst of intellectual activity in the early days of the Unitarian schism. No more was heard of the Westminster doctrine that man had lost all ability of will to any spiritual good accompanying salvation, but was dead in sin. So strong was the reaction against old dogmas that for thirty years society seemed less likely to resume the ancient faith in the Christian Trinity than to establish a new Trinity, in which a deified humanity should have place. Under the influence of Channing and his friends, human nature was adorned with virtues hardly suspected before, and with hopes of perfection on earth altogether strange to theology. The Church then charmed. The worth of man became under Channing’s teachings a source of pride and joy, with such insistence as to cause his hearers at last to recall, almost with a sense of relief, that the Saviour himself had been content to regard them only as of more value than many sparrows.

The most remarkable quality of Unitarianism was its high social and intellectual character. The other more popular religious movements followed for the most part a less ambitious path, but were marked by the same humanitarian tendency. In contrast with old stringency of thought, the religious activity of the epoch showed warmth of emotion. The elder Buckminster, a consistent Calvinist clergyman, settled at Portsmouth in New Hampshire, while greatly distressed by his son’s leanings toward loose theology, was at the same time obliged to witness the success of other opinions, which he thought monstrous, preached by Hosea Ballou, an active minister in the same town. This new doctrine, which took the name of Universalism, held as an article of faith “that there is one God, whose nature is love, revealed in one Lord Jesus Christ, by one Holy Spirit of grace, who will finally restore the whole family of mankind to holiness and happiness.” In former times any one who had publicly professed belief in universal salvation would not have been regarded as a Christian. With equal propriety he might have preached the divinity of Ammon or Diana. To the old theology one god was as strange as the other; and so deeply impressed was Dr. Buckminster with this conviction, that he felt himself constrained in the year 1809 to warn Hosea Ballou of his error, in a letter pathetic for its conscientious self-restraint. Yet the Universalists steadily grew in numbers and respectability, spreading from State to State under Ballou’s guidance, until they became as well-established and as respectable a church as that to which Buckminster belonged.

A phenomenon still more curious was seen in the same year, 1809, in western Pennsylvania. Near the banks of the Monongahela, in Washington County, a divergent branch of Scotch Presbyterianism established a small church, and under the guidance of Thomas Campbell, a recent emigrant from Scotland, issued, Sept. 7, 1809, a Declaration:

“Being well aware from sad experience of the heinous nature and pernicious tendency of religious controversy among Christians, tired and sick of the bitter jarrings and janglings of a party spirit, we would desire to be at rest; and were it possible, would also desire to adopt and recommend such measures as would give rest to our brethren throughout all the churches, as would restore unity, peace, and purity to the whole Church of God. This desirable rest, however, we utterly despair either to find for ourselves, or to be able to recommend to our brethren, by continuing amid the diversity and rancor of party contentions the varying uncertainty and clashings of human opinions; nor indeed can we reasonably expect to find it anywhere but in Christ and his simple word, which is the same yesterday, to-day, and forever. Our desire, therefore, for ourselves and our brethren would be that rejecting human opinions and the inventions of men as of any authority, or as having any place in the Church of God, we might forever cease from further contentions about such things, returning to and holding fast by the original standard.”
