If the First Epistle to the Corinthians was written a.d. 57, and if our author speaks with designed precision, and not in round numbers, the date of this treatise should be a.d. 217—a date which I should prefer to accept. Bishop Kaye, however, instances capp. 7 and 9 in the Ad Nationes as proving his disposition to give his numbers in loose rhetoric, and not with arithmetical accuracy. Pamelius, on the other hand, gives a.d. 213.
