The conception which the Catholic Church had of itself in the early third century can, perhaps, best be approached by pointing out that if we use the word "Christianity" we are unhistorical. "Christianity" is a term in the mouth and upon the pen of the post-Reformation writer; it connotes an opinion or a theory; a point of view; an idea. The Christians of the time of which I speak had no such conception. Upon the contrary, they were attached to its very antithesis. They were attached to the conception of a thing: of an organized body instituted for a definite end, disciplined in a definite way, and remarkable for the possession of definite and concrete doctrine. One can talk, in speaking of the first three centuries, of stoic_ism_, or epicurean_ism_, or neoplaton_ism_; but one cannot talk of "Christian_ism_" or "Christ_ism_." Indeed, no one has been so ignorant or unhistorical as to attempt those phrases. But the current phrase "Christianity," used by moderns as identical with the Christian body in the third century, is intellectually the equivalent of "Christianism" or "Christism;" and, I repeat, it connotes a grossly unhistorical idea; it connotes something historically false; something that never existed.

Let me give an example of what I mean:

Four men will be sitting as guests of a fifth in a private house in Carthage in the year 225. They are all men of culture; all possessed of the two languages, Greek and Latin, well-read and interested in the problems and half-solutions of their skeptical time. One will profess himself Materialist, and will find another to agree with him; there is no personal God, certain mora
