Clement of Rome (c. 30–100) was a bishop in the church at Rome and was a disciple of both Peter and Paul. He is referred to in Philippians 4:3:
I urge you also, true companion, help these women who labored with me in the gospel, with Clement also, and the rest of my fellow workers, whose names are in the Book of Life.
Therefore, you will write two books, and you will send the first to Clement and the other to Grapte. And Clement will send his to foreign countries, for permission has been granted to him to do so. Hermas (c. 150, W), 2.12
In the third place from the apostles, Clement was allotted the bishopric. Since he had seen the blessed apostles and had been conversant with them, this man might be said to have the preaching of the apostles still echoing in his ears and their traditions still before his eyes. Nor was he alone. For there were many others still remaining who had received instructions from the apostles. In the time of this Clement, no small dissension occurred among the brethren at Corinth. So the church in Rome dispatched a most powerful letter to the Corinthians, exhorting them to peace, renewing their faith, and declaring the tradition which it had lately received from the apostles. Irenaeus (c. 180, E/ W), 1.416
Now Clement, in his Epistle to the Corinthians, while expounding the differences of those who are approved according to the church, says expressly, “One may be a believer; one may be powerful in uttering knowledge.” Clement of Alexandria (c. 195, E), 2.308
In the Epistle to the Corinthians, the apostle Clement . . . says, “For who that has sojourned among you has not proved your perfect and firm faith?” Clement of Alexandria (c. 195, E), 2.428
Clement, in the Epistle to the Corinthians, says, “The greater someone seems to be, the more humble he should be.” Clement of Alexandria (c. 195, E), 2.495
Clement, indeed a disciple of the apostles, makes mention of those whom the Greeks called Antichthones, and other parts of the earth, to which none of our people can approach. Origen (c. 225, E), 4.273
But from what Clement seems to indicate when he says, “The ocean is impassable to men, and those worlds which are behind it,” speaking in the plural number of the worlds, . . . he wished the globe of the sun or moon—and of the other bodies called planets—to each be called “worlds.” Origen (c. 225, E), 4.274
Paul bears witness to the faithful Clement . . . when he says, “With Clement also, and the others, my fellow workers, whose names are in the book of life.” Origen (c. 228, E), 9.377.
Clement, the bishop and citizen of Rome, was the disciple of Paul. Apostolic Constitutions (compiled c. 390, E), 7.453
Papias of Hierapolis, the illustrious, was a disciple of the apostle who leaned on the bosom of Christ. He was also a disciple of Clement. Anastasius Sinaita, post-Nicene writer, 1.155; see also 2.429.
