John taken into exile died in Comana on the Euxine, on the 14th of September, in the following consulate, which was the seventh of Honorius, and the second of Theodosius. A man, as we have before observed, who on account of zeal for temperance was inclined rather to anger than forbearance: and his personal sanctity of character led him to indulge in a latitude of speech which to others was intolerable. Indeed, it is most inexplicable to me, how with a zeal so ardent for the practice of self-control and blamelessness of life, he should in his sermons appear to teach a loose view of temperance. For whereas by the Synod of bishops repentance was accepted but once from those who had sinned after baptism; he did not scruple to say, Approach, although you may have repented a thousand times.' For this doctrine, many even of his friends censured him, but especially Sisinnius bishop of the Novatian; who wrote a book condemnatory of the above quoted expression of Chrysostom's, and severely rebuked him for it. But this occurred long before.
