"He was the brother of the Apostle Barnabas and was born in Cyprus. He was a follower of the Apostle Paul, who mentions him in his Epistle to the Romans (16:10). When the great Apostle Paul created many bishops for different parts of the world, he made this Aristobulus bishop of Britain (i.e. England). In Britain there was a wild people, pagan and wicked, and Aristobulus endured among them unmentionable torments, misfortunes and malice. They smote him without mercy, dragged him through the streets, mocked him and jeered at him. But in the end this holy man came to success by the power of the grace of God. He enlightened the people, baptised them in the name of Christ the Lord, built churches, ordained priests and deacons and finally died there in peace and went to the Kingdom of the Lord whom he had served so faithfully."
