55 But if this record of events is false, as you say, how comes it that in so short a time the whole world has been filled with such a religion? Or how could nations dwelling widely apart, and separated by climate and by the convexities of heaven, unite in one conclusion? They have been prevailed upon, say my opponents, by mere assertions, been led into vain hopes; and in their reckless madness have chosen to incur voluntarily the risks of death, although they had hitherto seen nothing of such a kind as could by its wonderful and strange character induce them to adopt this manner of worship. Nay, because they saw all these things to be done by Christ Himself and by His apostles, who being sent throughout the whole world carried with them the blessings of the Father, which they dispensed in benefiting as well the minds as the bodies of men; overcome by the force of the very truth itself they both devoted themselves to God, and reckoned it as but a small sacrifice to surrender their bodies to you and to give their flesh to be mangled.
