The doctrine, style, and manner of thought are all in accordance with it; so that, although, as has been said, positive certainty cannot be reached on the subject, we may with great probability conclude that we have in this epistle a composition of that Clement who is known to us from Scripture as having been an associate of the great apostle. ”
