Here is Ballou's catechism, composed for his flock (The Catechism of Non-Resistance[4]):
Q. Whence originated the term "non-resistance?"
A. From the injunction, "Resist not evil," Matt. v. 39.
Q. What does the term signify?
A. It expresses a high Christian virtue, prescribed by Christ.
Q. Is the word "resistance" to be taken in its widest meaning, that is, as showing that no resistance whatever is to be shown to evil?
A. No, it is to be taken in the strict sense of the Saviour's injunction; that is, we are not to retaliate evil with evil. Evil is to be resisted by all just means, but never with evil.
Q. From what can we see that Christ in such cases prescribed non-resistance?
A. From the words which He then used. He said, "Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth. But I say unto you that ye resist not evil; but whosoever shall smite thee on thy right cheek, turn to him the other also. And if any man will sue thee at the law, and take away thy coat, let him have thy cloak also."
Q. To whom does Jesus refer in the words, "It has been said?"
