Tertullian

“ For what mark do we exhibit except the prime wisdom, [20] which teaches us not to worship the frivolous works of the human hand; the temperance, by which we abstain from other men’s goods; the chastity, which we pollute not even with a look; the compassion, which prompts us to help the needy; the truth itself, which makes us give offence ”

“ As soon as they discovered them to be Christians, they wished they were criminals again; for our discipline carries its own evidence in itself, nor are we betrayed by anything else than our own goodness, just as bad men also become conspicuous [19] by their own evil. Else how is it that we alone are, contrary to the lessons of nature, branded as very evil because of our good? ”

“ And yet it is the truth, which is so troublesome to the world, that these philosophers affect, but which Christians possess: they therefore who have it in possession afford the greater displeasure, because he who affects a thing plays with it; he who possesses it maintains it. For example, [8] Socrates was condemned on that side (of his wisdom) in which he came nearest in his search to the truth, by destroying your gods. Although the name of Christian was not at that time in the world, yet truth was always suffering condemnation. ”

“ It occurs to none (to consider) whether a man is not good and wise because he is a Christian, or therefore a Christian because he is wise and good, although it is more usual in human conduct to determine obscurities by what is manifest, than to prejudice what is manifest by what is obscure. ”
