Saint Aristarchus was one of the Seventy Apostles, whom the Lord Jesus Christ sent to proclaim the good news of the Gospel (Luke. 10:1-24).
Saint Aristarchus, a co-worker of the holy Apostle Paul, became bishop of the Syrian city of Apamea. His name is repeatedly mentioned in the Acts of the Holy Apostles (Acts 19:29, 20:4, 27:2) and in the Epistles of Saint Paul (Col. 4:10, Philemon 1:24). He accompanied Saint Paul on his travels (Acts 16:29), and was Bishop of Apamea, Syria.
Saint Aristarchus is also commemorated on April 15 with Saints Pudens and Trophimus and on September 27 together with Saints Mark and Zenas.
