I knew very little, like the rest of us, as to what had been done and preached and written in former days on this subject of non-resistance to evil. I knew what had been said on this subject by the fathers of the church, Origen, Tertullian, and others, and I knew also that there have existed certain so-called sects of the Mennonites, Herrnhuters, Quakers, who do not admit for a Christian the use of weapons and who do not enter military service, but what had been done by these so-called sects for the solution of this question was quite unknown to me. My book, as I expected, was held back by the Russian censor, but, partly in consequence of my reputation as a writer, partly because it interested people, this book was disseminated in manuscripts and lithographic reprints in Russia and in translations abroad, and called forth, on the one hand, on the part of men who shared my views, a series of references to works written on the subject, and, on the other, a series of criticisms on the thoughts expressed in that book itself. Both, together with the historical phenomena of recent times, have made many things clear to me and have brought me to new deductions and conclusions, which I wish to express. First I shall tell of the information which I received concerning the history of the question of non-resistance to evil, then of the opinions on this subject which were expressed by ecclesiastic critics, that is, such as profess the Christian religion, and also by laymen, that is, such as do not profess the Christian religion; and finally, those deductions to which I was brought by both and by the historical events of recent times. I. Among the first answers to my book there came some letters from the American Quakers. In these letters, which express their sympathy with my views concerning the unlawfulness for Christianity of all violence and war, the Quakers informed me of the details of their so-called sect, which for more than two hundred years has in fact professed Christ's teaching about non-resistance to evil, and which has used no arms in order to defend itself. With their letters, the Quakers sent me their pamphlets, periodicals, and books. From these periodicals, pamphlets, and books which they sent me I learned to what extent they had many years ago incontestably proved the obligation for a Christian to fulfil the commandment about non-resistance to evil and had laid bare the incorrectness of the church teaching, which admitted executions and wars.
