For when they, though established in a lie, use every means to conceal the shamefulness of their opinions, while we, the servants of the truth, cannot even open our mouths, how can they help condemning the great weakness of our doctrine? how can they help suspecting our religion to be fraud and folly? how shall they not blaspheme Christ as a deceiver, and a cheat, who used the folly of the many to further his fraud? And we are to blame for this blasphemy, because we will not be wakeful in arguments for godliness, but deem these things superfluous, and care only for the things of earth. He who admires a dancer or a charioteer, or one who contends with beasts, uses every exertion and contrivance not to come off worst in any disputes concerning him, and they string together long panegyrics, as they compose their defense against those who find fault with them, and cast sneers without number at their opponents: but when arguments for Christianity are proposed, they all hang their heads, and scratch themselves, and gape, and retire at length the objects of contempt.
