CLEMENT I., Saint, generally known as Clement of Rome, or CLEMENS ROMANUS (fl. C. A.D. 96), was one of the "Apostolic Fathers," and in the lists of bishops of Rome is given the third or fourth place—Peter, Linus (Anencletus), Clement. There is no ground for Origen's identification of him with the Clement of Phil. iv. 3. He may have been a freedman of T. Flavius Clemens, who was consul with his cousin, the emperor Domitian, in A.D. 95. He is commemorated on Nov. 23.
We learn from the letter (i. 7) that the Church at Rome, though persecuted, was firmly held together by faith and love. The epistle was publicly read from time to time at Corinth, and by the 4th century this usage had spread to other churches. It is attached to the famous Alexandrian ms. (Codex A) of the New Testament, but this does not imply that it ever reached canonical rank. For the mass of early Christian literature that was gradually attached to Clement's name see CLEMENTINE LITERATURE.
The epistle was published in 1633 by P. Young from Cod. Alexan drinus, in which a leaf near the end was missing, so that the great prayer (cc. lv.—lxiv.) remained unknown. In 1875 (six years after J. B. Lightfoot's first edition) Bryennius (q.v.) published a complete text from a Constantinople ms. dated 1055 from which in 1883 he gave us the Didache. In 1876 R. L. Bensly found a complete Syriac text in a ms. in the University library, Cambridge. Lightfoot made use of these new materials in an Appendix (1877) (2nd ed. with excellent excursus and Eng. trans. in The Apostolic Fathers vol. i., 189o) . Dom Morin discovered a Latin version (1894) , probably of the 3rd century, which is a valuable addition to the authorities for the text. Its evidence is used in the edition by R. Knopf (Leipzig, 1899). See also W. Wrede, Untersuchungen zum ersten Clemensbrief (1891), and other literature cited in Herzog-Hauck's Realencyklopddie.
