Lord of all truth and peace, you raised up your bishop John to be servant of the servants of God and gave him wisdom to call for the work of renewing your Church: Grant that, following his example, we may reach out to other Christians to clasp them with the love of your Son, and labor throughout the nations of the world to kindle a desire for justice and peace; through Jesus Christ, who is alive and reigns with you and the Holy Spirit, one God, now and for ever. Amen.
