In the year 1884 I wrote a book under the title "What I Believe," in which I did in fact make a sincere statement of my beliefs. In affirming my belief in Christ's teaching, I could not help explaining why I do not believe, and consider as mistaken, the Church's doctrine... Among the many points in which this doctrine falls short of the doctrine of Christ I pointed out as the principal one the absence of any commandment of non-resistance to evil by force. The perversion of Christ's teaching by the teaching of the Church is more clearly apparent in this than in any other point of difference.
