Clement in Fausset's Bible Dictionary

Paul's fellow helper at Philippi, whom Origen (Commentary, John 1:29) identifies with the Clement, the apostolical father afterward bishop of Rome, whose epistle to the Corinthian church (part of the Alexandrius manuscript of Greek Old and New Testament) is extant. Philippi being closely connected with Rome, as a Roman colony, might easily have furnished a, bishop to the Roman church.
