The Holy Apostle Clement of the Seventy was bishop in Sardica (an ancient wealthy city of Lydia in Asia Minor). The holy Apostle Paul mentions his name in the Epistle to the Philippians (Phil. 4:3). Addressing a certain “sincere co-worker of his”, Paul entreats him: “Help those women who labored with me in the Gospel, and with Clement and my other co-workers, whose names are in the Book of Life” (January 4).
Saint Clement is also commemorated on April 22.
