Freemasonry... has no pretension to assume a place among the religions of the world as a sectarian "system of faith and worship," in the sense in which we distinguish Christianity from Judaism, or Judaism from Mohammedanism. In this meaning of the word we do not and can not speak of the Masonic religion, nor say of a man that he is not a Christian, but a Freemason. Here it is that the opponents of Freemasonry have assumed mistaken ground in confounding the idea of a religious Institution with that of the Christian religion as a peculiar form of worship, and in supposing, because Freemasonry teaches religious truth, that it is offered as a substitute for Christian truth and Christian obligation.
