Aristarchus of Thessalonica

Aristarchus or Aristarch (Greek: Ἀρίσταρχος Aristarkhos), "a Greek Macedonian of Thessalonica" (Acts 27:2), was an early Christian mentioned in a few passages of the New Testament. He accompanied Saint Paul on his journey to Rome. Along with Gaius, another Macedonian, Aristarchus was seized by the mob at Ephesus and taken into the theater (Acts 19:29). Later, Aristarchus returned with Paul from Greece to Asia (Acts 20:4). At Caesarea, he embarked with Paul on a ship of Edremit (Adramyttium) bound for Myra in Lycia (Acts 27:2); whether he traveled with him from there to Rome is not recorded. Aristarchus is described as Paul's "fellow prisoner" and "fellow laborer" in Colossians 4:10 and Philemon 1:24, respectively.

In Eastern Orthodox and Eastern Catholic tradition, Aristarchus is identified as one of the Seventy Apostles and bishop of Apamea. He is commemorated as a saint and martyr on January 4, April 14, and September 27.
