Again I heard, in substance, this language, and could not distinguish it from Popery. “Christianity must have its essentials; these to us are the Deity of Christ; the corruption of human nature; and the remedy of a vicarious sacrifice. The Unitarians who deny these points we therefore do not hold to be Christians, and not believing them to be so, we plainly tell them so.” And accordingly they treat us as if we were not. Now I acknowledge that this is entirely consistent upon their part. They make the essentials of Christianity to consist in doctrinal ideas, and consequently, whether they choose it or not, and almost without knowing it, they are forced to assume the tones of Popish Infallibility, and to decide authoritatively, by their metaphysical standard, who are Christians and who are not. I am quite aware that this is not intentional arrogance on their part, but a necessity in which their first principles involve them. They cannot begin with a Salvation through creeds, without ending in Popery; and of all the forms of Popery, that which professes Protestantism, is the most offensive. It was a fresh proof to me of the authoritative character which Trinitarianism by necessity assumes, when I heard naturally and unconsciously the same kind of doctrinal compactness ascribed to ourselves, as if a church could not exist without a fixed creed; and quotations from all sorts of minds brought forward, without a suspicion, but they were all received among us as recognized standards of opinion. There were Arians and Humanitarians, Necessarians and Libertarians, and one foreign writer, who, as I am informed, was no Christian at all—and all these were appealed to as standards of Unitarianism. Now we certainly glory in it that our religion does not destroy our individuality; that in consistency with the great principle of Christ being our Leader, we tolerate freely intellectual differences, and encourage the virtues of free thought and speech; but it is a little unfortunate, and a little unfair, if the fundamental principles of Unitarian Theology and Religion are to be answerable, with their life, for all the sayings of all the Unitarians from Marcion and the Ebionites down to the present day. Take one form of Unitarianism as it is represented by Priestley; or take another and better form of it as it is represented by Channing; but do not confuse in one two minds so radically different, and call a combination which never had existence, the Unitarian Faith. It was owing to this Popish idea that all Religions must have a doctrinal compactness, that I heard a sentiment of Priestley’s, which I entirely disown, imputing idolatry to Trinitarians, ascribed to all Unitarians. If Unitarians worshipped Christ not believing him to be God _they_ would be idolaters: but Trinitarians worshipping one God in three persons, and still believing him to be one, are as certainly not Polytheists. Again I heard the Improved Version
