All such views of Christianity imply that there is no sufficient body of historical proof to interfere with, or at least to prevail against, any number whatever of free and independent hypotheses concerning it. But this surely is not self-evident, and has itself to be proved. Till positive reasons grounded on facts are adduced to the contrary, the most natural hypotheses, the most agreeable to our mode of proceeding in parallel cases, and that which takes precedence of all others, is to consider that the society of Christians, which the Apostles left on earth, were of that religion to which the Apostles had converted them; that the external continuity of name, profession, and communion, argues a real continuity of doctrine; that, as Christianity began by manifesting itself as of a certain shape and bearing to all mankind, therefore it went on so to manifest itself; and that the more, considering that prophecy had already determined that it was to be a power visible in the world and sovereign over it, characters which are accurately fulfilled in that historical Christianity to which we commonly give the name. It is not a violent assumption, then, but rather mere abstinence from the wanton admission of a principle which would necessarily lead to the most vexatious and preposterous scepticism, to take it for granted, before proof to the contrary, that the Christianity of the second, fourth, seventh, twelfth, sixteenth, and intermediate centuries is in its substance the very religion which Christ and His Apostles taught in the first, whatever may be the modifications for good or for evil which lapse of years, or the vicissitudes of human affairs, have impressed upon it. Of course I do not deny the abstract possibility of extreme changes. The substitution is certainly, in idea, supposable of a counterfeit Christianity,--superseding the original, by means of the adroit innovations of seasons, places, and persons, till, according to the familiar illustration, the "blade" and the "handle" are alternately renewed, and identity is lost without the loss of continuity. It is possible; but it must not be assumed. The _onus probandi_ is with those who assert what it is unnatural to expect; to be just able to doubt is no warrant for disbelieving. 4.
