Almighty God, who gave your servant Theodore of Tarsus gifts of grace and wisdom to establish unity where there had been division and order where there had been chaos: Create in your church, by the operation of the Holy Spirit, such godly union and concord that it may proclaim, both by word and example, the Gospel of the Prince of Peace; who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
— Book of Common Prayer
