Catholic Encyclopedia (1913)/St. Tychicus
A disciple of St. Paul and his constant companion. He was a native of the Roman province of Asia (Acts, xx, 4), born, probably, at Ephesus. About his conversion nothing is known. He appears as a companion of St. Paul in his third missionary journey from Corinth through Macedonia and Asia Minor to Jerusalem. He shared the Apostle's first Roman captivity and was sent to Asia as the bearer of letters to the Colossians and Ephesians (Eph., vi, 21; Col, iv, 7, 8). According to Tit., iii, 12, Paul intended to send Tychicus or Artemas to Crete to supply the place of Titus. It seems, however, that Artemas was sent, for during the second captivity of St. Paul at Rome Tychicus was sent thence to Ephesus (II Tim., iv, 12). Of the subsequent career of Tychicus nothing certain is known. Several cities claim him as their bishop. The Menology of Basil Porphyrogenitus, which commemorates him on 9 April, makes him Bishop of Colophon and successor to Sosthenes. He is also said to have been appointed Bishop of Chalcedon by St. Andrew the Apostle (Lipsius, "Apokryphe Apostelgesch.", Brunswick, 1883, 579). He is also called bishop of Neapolis in Cyprus (Le Quien, "Oriens christ.", Paris, 1740, I, 125; II, 1061). Some martyrologies make him a deacon, while the Roman Martyrology places his commemoration at Paphos in Cyprus. His feast is kept on 29 April.
