The Holy Apostle Aristobulus of the Seventy was born on Cyprus. He and his brother, the holy Apostle Barnabas of the Seventy, accompanied the holy Apostle Paul on his journeys. St Aristobulus is mentioned by the Apostle Paul in the Epistle to the Romans (Rom 16:10).
St Paul made Aristobulus a bishop and sent him to preach the Gospel in Britain, where he converted many to Christ. He endured the torments and malice of the pagans, and eventually baptized them.
St Aristobulus died in Britain among the people he had evangelized. His memory is celebrated on October 31 and also on the Synaxis of the Seventy Apostles January 4.
