St. Theodore was born in Tarsus, and after he became a priest, he came to the attention of the Pope, who decided to send him to Britain to become the seventh archbishop of Canterbury. He was consecrated in 668, and became the first archbishop to rule the whole English Church. After his consecration he set out from Rome with St. Adrian, who had been abbot of a monastery, and also St. Benedict Biscop, who would become one of the great English abbots.
In 669 they reached Canterbury, where Theodore made Adrian the abbot of SS. Peter and Paul monastery, afterward named St. Augustine's. There they created a famous school influential in the lives of such brilliant scholars as the celebrated historian St. Bede the Venerable and the skilled church architect St. Aldhelm.
Theodore set about organizing the Church throughout England. Many of the sees had no bishops when he first arrived, and others sees needed to be divided. In 672 he called the first general synod of the bishops of the English Church to settle many important questions about the discipline and life of the Church in England.
Theodore's greatest achievement was to adapt the Roman ideal of a centralized church to English conditions. His establishment of a centralized church under the archbishopric of Canterbury in close alliance with secular rulers was maintained by his successors.
Theodore and Adrian brought organization and education to the English Church, and what they established there continue on to this day, even in parishes such as our own, which follow many of the traditions they began.
O God, whose Bishop Theodore was called to England to set the Church on a firm foundation: by his prayers, build us always anew on the rock that is Christ; and keep thy household faithful to the call we have received; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
