The holy, glorious and all-laudable Apostle Aristarchus (also Aristarchos) of the Seventy was chosen by Jesus Christ to preach the good news contained in the Gospel. St. Aristarchus is commemorated with the Seventy on January 4, on April 14 or 15 with Ss. Pudens and Trophimus, and on September 27 together with Ss. Mark and Zenas.
Aristarchus worked with the holy Apostle Paul in order to enlighten others with the written works of the Gospel. He was St. Paul's disciple and later became bishop of the city of Apamea in Syria.
He gave up his life and became a martyr under Emperor Nero.
