Christians are civilized

We do not teach in an uncivilized way, we do not pelt our enemies with insults which is what most people do, fighting not against arguments but against those who propose them; at times, too, they cover over the weakness of their reasoning with invective, like the cuttlefish who, they say, belches forth ink before itself to give its predators the slip, or to hunt without being seen. But we try to show that fighting the war on Christ’s behalf consists in fighting as Christ did—the meek one, the peacemaker, who sustains our weaknesses.”
— Saint Gregory of Nazianzus
