13.

God be thanked that the men of Hippo regard his promise of residence here as kept fully, if only he come with the intention of making this town his home, and in going whithersoever necessity may call him, go with the intention of coming back to us again. For if they were to exact literal fulfilment of the words of the promise, it would be the duty of a servant of God to adhere to every sentence of it rather than forswear himself. But as it would be a crime for them so to bind any one, much more such a man as he is, so they have themselves proved that they had no such unreasonable expectation; for on hearing that he had gone away with the intention of returning, they expressed their satisfaction; and fidelity to an oath requires no more than the performance of what was expected by those to whom it was given. Let me ask, moreover, what is meant by saying that he, in giving the oath with his own lips, mentioned the possibility of necessity preventing his fulfilment of the promise? The truth is, that with his own lips he ordered the qualifying clause to be removed. If he put it in, it would be when he himself spoke to the people; but if he had done so, they assuredly would not have answered, "Thanks be unto God," but would have renewed the protestations which they made when it was read with the qualifying clause by the deacon. And what difference does it really make whether this plea of necessity for departing from the promise was or was not inserted? Nothing more than we have stated above was expected from him; but he who disappoints the known expectation of those to whom his oath is given, cannot but be a perjured person.
