I have said these things, because I once heard a Christian disputing in a ridiculous manner with a Greek, and both parties in their mutual fray ruining themselves. For what things the Christian ought to have said, these the Greek asserted; and what things it was natural to expect the Greek would say, these the Christian pleaded for himself. As thus: the dispute being about Paul and Plato, the Greek endeavored to show that Paul was unlearned and ignorant; but the Christian, from simplicity, was anxious to prove that Paul was more eloquent than Plato. And so the victory was on the side of the Greek, this argument being allowed to prevail. For if Paul was a more considerable person than Plato, many probably would object that it was not by grace, but by excellency of speech that he prevailed; so that the Christian's assertion made for the Greek. And what the Greek said made for the Christian's; for if Paul was uneducated and yet overcame Plato, the victory, as I was saying, was brilliant; the disciples of the latter, in a body, having been attracted by the former, unlearned as he was, and convinced, and brought over to his side. From whence it is plain that the Gospel was a result not of human wisdom, but of the grace of God.
Wherefore, lest we fall into the same error, and be laughed to scorn, arguing thus with Greeks whenever we have a controversy with them; let us charge the Apostles with want of learning; for this same charge is praise. And when they say that the Apostles were rude, let us follow up the remark and say that they were also untaught, and unlettered, and poor, and vile, and stupid, and obscure.
