Archippus in the Bible Encyclopedia - ISBE

ar-kip'-us (Archippos): Addressed by Paul in his letter to Philem, as "our fellow-soldier"; probably a member of Philem's family circle, holding some official position in the church (Col 4:17; Philem 1:2). See APPHIA. The tradition that he was one of the seventy disciples, became bishop of Laodicea and later became a martyr, seems to have little historical foundation.
