“The rapid establishment of Christianity must therefore have been from the conviction which those who embraced it, had of its "Truth and power unto salvation." Christianity at first spread itself amongst the most enlightened nations of the earth - in those places where human learning was in its greatest perfection; and, by the force of the evidence which attended it, amongst such men it gained an establishment. It has been justly observed, that "it happened very providentially to the honour of the Christian religion, that it did not take its rise in the dark illiterate ages of the world, but at a time when arts and sciences were t their height, and when there were men who made it the business of their lives to search after truth and lift the several opinions of the philosophers and wise men, concerning the duty, the end, and chief happiness of reasonable creatures." Both the learned and the ignorant alike embraced its doctrines; the learned were not likely to be deceived in the proofs which were offered; and the same cause undoubtedly operated to produce the effect upon each. But an immediate conversion of the bulk of mankind, can arise only from some proofs of a ddivine authority offering themselves immediately to the senses; the preaching of any new doctrine, if lest to operate only by its own force, would go but a very little way towards the immediate conversion of the gnorant, who have no principle of action but what arises from habit, and whose powers of reasoning are insufficient to correct their errors. When Mahomet was required by his followers to work a miracle for their conviction, he always declined it; he was too cautious to trust to an experiment, the success of which was scarcely whithin the bounds of probablity; he amused his followers with prtended visions, which with the aid afterwards of the civil and military powr; and as the accomplishment of that event was by a few obscure persons, who founded their pretentions upon authority from heaven, we are next to consider, what kind of proofs of their divine commission they offered to the world; and whether they themselves could have been deceived, or mankind could have been deludded by them.”
