It was in such tendencies as these, as they were developed in Holland and England, that American Unitarianism had its origin. To show how true this is, it may be desirable to speak of a few of the men whose books were most frequently read in New England during the eighteenth century. The prose writings of Milton exerted great influence in favor of toleration and in vindication of reason. Without doubt he became in his later years a believer in free will and the subordinate nature of Christ, and he was true to the Protestant ideal of an open Bible and a free spirit in man. Known as a Puritan, his pleas for toleration must have been read with confidence by his coreligionists of New England; while his rational temper could not have failed to have its effect.
His vindication of the Bible as the religion of Protestants must have commended Chillingworth to the liberal minds in New England; and there is evidence that he was read with acceptance, although he was of the established church. Chillingworth was of the noblest type of the latitudinarians in the Church of England during the first half of the seventeenth century; for he was generously tolerant, his mind was broad and liberal, and he knew the true value of a really comprehensive and inclusive church, which he earnestly desired should be established in England. He wished to have the creed reduced to the most limited proportions by giving emphasis to what is fundamental, and by the extrusion of all else. It was his desire to maintain what is essential that caused him to say: "I am fully assured that God does not, and therefore that man ought not, to require any more of any man than this--to believe the Scripture to be God's word, to endeavor to find the true sense of it, and to live according to it."[[7]]
He would therefore leave every man free to interpret the Bible for himself, and he would make no dogmatic test to deprive any man of this right. The chief fact in the Bible being Christ, he insisted that Christianity is loyalty to his spirit. "To believe only in Christ" is his definition of Christianity, and he would add nothing to this standard. He would put no church or creed or council between the individual soul and God; and he would direct every believer to the Bible as the free and open way of the soul's access to divine truth. He found that the religion of Protestants consisted in the rational use of that book, and not in the teachings of the Reformers or in the confessions they devised. It is the great merit of Chillingworth that he vindicated the spirit of toleration in a broad and noble manner, that he was without sectarian prejudice or narrowness in his desire for an inclusive church, and that he spoke and wrote in a truly rational temper. He applied reason to all religious problems, and he regarded it as the final judge and arbiter. Religious freedom received from him the fullest recognition, and no one has more clearly indicated the scope and purpose of toleration.
Another English religious leader, much read in New England, was Archbishop Tillotson. It has been said of him that "for the first time since the Reformation the voice of reason was now clearly heard in the high places of the church."[[8]] He was an Arminian in his sympathies, and held that the way of salvation is open to all who choose to accept its opportunities. He expressed himself as being as certain that the doctrine of eternal decrees is not of God as he was sure that God is good and just. His ground for this opinion was that it is repugnant to the convictions of justice and goodness natural to men. He maintained that we shall be justified before God by means of the reformation that is wrought in our own lives. We have an intuition of what is right, and a natural capacity for living justly and righteously. Experience and reason he made concomitant spiritual forces with the Bible, and he held that revelation is but a republication of the truths of natural religion. Tillotson was truly a broad churchman, who was desirous of making the national church as comprehensive as possible; and he was one who practised as well as preached toleration.
Not less liberal was Jeremy Taylor, who was numbered among the dissenters. In the introduction to his Liberty of Prophesying he said, "So long as men have such variety of principles, such several constitutions, educations, tempers, and distempers, hopes, interests, and weaknesses, degrees of light and degrees of understanding, it was impossible all should be of one mind." Taylor justly said that in heaven there is room for all faiths. His Liberty of Prophesying, Chillingworth's Religion of Protestants, and Milton's Liberty of Unlicensed Printing are the great expressions of the spirit of toleration in the seventeenth century. Each was broad, comprehensive, and noble in its plea for religious freedom. It has been said of Taylor that "he sets a higher value on a good life than on an orthodox creed. He estimates every doctrine by its capacity to do men good."[[9]]
Another advocate of toleration was John Locke, whose chief influence was as a rationalist in philosophy and religion. While accepting Christianity with simple confidence, he subjected it to the careful scrutiny of reason. His philosophy awakened the rationalistic spirit in all who accepted it, so that many of his disciples went much farther than he did himself. While accepting revelation, he maintained that natural knowledge is more certain in its character. He taught that the conclusions of reason are more important than anything given men in the name of revelation. He did not himself widely depart from the orthodoxy of his day, though he did not accept the doctrine of the Trinity in the most approved form.
One of the rationalistic followers of Locke was Samuel Clarke, who attempted to apply the scientific methods of Newton to the interpretation of Christianity. He tried to establish faith in God on a purely scientific basis. He declared that goodness does not exist because God commands it, but that he commands it because it is good. He interpreted the doctrine of the Trinity in a rationalistic manner, holding to its form, but rejecting its substance.
These men were widely read in New England during the eighteenth century. In England they were accounted orthodox, and they held high positions either in the national church or in the leading dissenting bodies. They were not sectarian or bigoted, they wished to give religion a basis in common sense and ethical integrity, and they approved of a Christianity that is practical and leads to noble living.
When we consider what were the relations of the colonies to England during the first half of the eighteenth century, and that the New England churches were constantly influenced by the religious attitude of the mother-country,[[10]] it is plain enough that toleration and rationalism were in large measure received from England. In the same school was learned the lesson of a return to the simplicity of Christ, of making him and his life the standard of Christian fellowship. The great leaders in England taught positively that loyalty to Christ is the only essential test of Christian duty; and it is not in the least surprising the same idea should have found noble advocacy in New England. That a good life and character are the true indications of the possession of a saving faith was a thought too often uttered in England not to find advocacy in the colonies.
In this way Unitarianism had its origin, in the teachings of men who were counted orthodox in England, but who favored submitting all theological problems to the test of reason. It was not a sectarian movement in its origin or at any time during the eighteenth century; but it was an effort to make religion practical, to give it a basis in reality, and to establish it as acceptable to the sound judgment and common sense of all men. It was an application to the interpretation of theological problems of that individualistic spirit which was at the very source of Protestantism. If the individual ought to interpret the Bible for himself, so ought he to accept his own explanation of the dogmas of the church. In so doing, he necessarily becomes a rationalist, which may lead him far from the traditions of the past. If he thinks for himself, there is an end to uniformity of faith--a conclusion which such men as Chillingworth and Jeremy Taylor were willing to accept; and, therefore, they desired an all-inclusive church, in order that freedom and unity of faith might be both maintained.
