With Christ, I Condemn All Falsehood

He has tried, it is true, to brand us with the stain of this false teaching by speaking to some of our brothers, and he repeats it in various letters, following his well-known plan of action. What he may write or claim is nothing to me. But since he raises this question of a doctrine of perjury, I will state my own opinion on it, and then leave him to pass judgment on himself. It is this. Our Lord and Savior says in the Gospels, “It was said to those of old, You shall not swear falsely, but shall pay your vows to the Lord. But I say to you, Do not swear at all.” So I say that everyone who teaches that we may swear falsely for any cause whatever is a stranger to the faith of Christ and to the unity of the catholic church.
