The truth is that Masonry is undoubtedly a religious institution, its religion being of that universal kind in which all men agree. - Albert Mackey

To few Freemasons of the present day, except to those who have made Freemasonry a subject of especial study, is the name of Desaguliers very familiar. But it is well that they should know that to him, perhaps, more than to any other man, are we indebted for the present existence of Freemasonry as a living Institution, for it was his learning and social position that gave a standing to the Institution, which brought to its support noblemen and men of influence so that the insignificant assemblage of four London Lodges at the Apple-Tree Tavern has expanded into an association which now shelters the entire civilized world. And the moving spirit of all this was John Theophilus Desaguliers.

A system is a plan or scheme of doctrines intended to develop a particular view.

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.
