3. He has

endeavoured, indeed, to brand us with the stain of this false teaching

by speaking to some of our brethren, and he repeats this by various

letters, according to his recognized plan of action. It is nothing to

me what he may write or assert, but, since he raises this question

about a doctrine of perjury, I will state my opinion upon it, and then

leave him to pass judgment upon himself. It is this. Since our Lord and

Saviour says in the Gospels “It was said to them of old time, Thou shalt not forswear thyself, but shalt pay to the Lord thy vows, but I say unto you, Swear not at all;” I say that every one who teaches that for any cause whatever we may swear falsely, is alien from the faith of Christ and from the unity of the catholic church.
