I know-as we all do-very little of the practice and the spoken and written doctrine of former times on the subject of non-resistance to evil. I knew what had been said on the subject by the fathers of the Church-Origen, Tertullian, and others-I knew too of the existence of some so-called sects of Mennonites, Herrnhuters, and Quakers, who do not allow a Christian the use of weapons, and do not enter military service; but I knew little of what had been done by these so-called sects toward expounding the question.
