. . . . The Christians, O King, have found the truth by going and seeking for it. . . . They do not do to others what they would not have done to themselves. They comfort those who wrong them and make friends of them: they labour to do good to their enemies. . . . He that has gives freely to him who has not. If they see a stranger, they bring him under their roof and rejoice over him as if over their own brother: they call themselves brethren, not after the flesh but after the Spirit and in God . . . .
Aristides, Apology, 15 (to the Emperor Hadrian, c130AD)
