Clement is mentioned in Phil. iv. 3, but is not called a “fellow-soldier.” Eusebius was evidently thinking of Paul’s references to Epaphroditus (Phil. ii. 25) and to Archippus (Philem. 2), whom he calls his fellow-soldiers. The Clement to whom Eusebius here refers was a very important personage in the early Roman church, being known to tradition as one of its first three bishops. He has played a prominent part in Church history on account of the numerous writings which have passed under his name. We know nothing certain about his life. Eusebius identifies him with the Philippian Clement mentioned by Paul,—an identification apparently made first by Origen, and after him repeated by a great many writers. But the identification is, to say the least, very doubtful, and resting as it does upon an agreement in a very common name deserves little consideration. It was quite customary in the early Church to find Paul’s companions, whenever possible, in responsible and influential positions during the latter part of the first century. A more plausible theory, which, if true, would throw an interesting light upon Clement and the Roman church of his day, is that which identifies him with the consul Flavius Clement, a relative of the emperor Domitian (see below, chap. 18, note 6). Some good reasons for the identification might be urged, and his rank would then explain well Clement’s influential position in the Church. But as pointed out in chap. 18, note 6, it is extremely improbable that the consul Flavius Clement was a Christian; and in any case a fatal objection to the identification (which is nevertheless adopted by Hilgenfeld and others) is the fact that Clement is nowhere spoken of as a martyr until the time of Rufinus, and also that no ancient writer identifies him or connects him in any way with the consul, although Eusebius’ mention of the latter in chap. 23 shows that he was a well-known person. When we remember the tendency of the early Church to make all its heroes martyrs, and to ascribe high birth to them, the omission in this case renders the identification, we may say, virtually impossible. More probable is the conjecture of Lightfoot, that he was a freedman belonging to the family of the consul Clement, whose name he bore. This is simply conjecture, however, and is supported by no testimony. Whoever Clement was, he occupied a very prominent position in the early Roman church, and wrote an epistle to the Corinthians which is still extant (see below, chap. 16; and upon the works falsely ascribed to him, see chap. 38). In regard to his place in the succession of Roman bishops, see chap. 2, note 1, above. For a full account of Clement, see especially Harnack’s Prolegomena to his edition of Clement’s Epistle (Patrum Apost. Opera, Vol. 1.), Salmon’s article, Clemens Romanus, in the Dict. of Christ. Biog., Schaff’s Ch. Hist. II. 636 sq., and Donaldson’s Hist. of Christ. Lit. and Doctrine, I. p. 90 sq.
