The Week of Prayer for Christian Unity began in 1908 as the Octave of Christian Unity, and focused on prayer for church unity which begins on the Feast of the Confession of Peter on January 18 and concludes with the Feast of the Conversion of Saint Paul on January 25. (Wikipedia)
O God who has called men and women in every land to be a holy nation, a royal priesthood, the Church of your dear Son; unite us in mutual love across the barriers of race and culture, and strengthen us here in Monroe in our common task of being Christ and showing Christ to the world he came to save. Amen. (John Kingsnorth (USPG))
O God, be with thy Church everywhere and particularly in the Churches of Monroe. May she walk warily in times of peace and quietness, and boldly in times of trouble. Do thou remove all harshness and bitterness from amongst us, towards those who walk not in all things with us, but who worship our Lord in sincerity and truth. And all this we ask for the sake of thy dear Son. Amen. (Helen Waddell, 1889-1965)
Prayers for the Feast Days (from the BCP):
Confession of Saint Peter January 18
Almighty Father, who inspired Saint Peter, first among the apostles, to confess Jesus as Messiah and Son of the living God: Keep your Church steadfast upon the rock of this faith, so that in unity and peace we may proclaim the one truth and follow the one Lord, our Savior Jesus Christ; who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.Conversion of Saint Paul January 25
O God, by the preaching of your apostle Paul you have caused the light of the Gospel to shine throughout the world:Grant, we pray, that we, having his wonderful conversion in remembrance, may show ourselves thankful to you by following his holy teaching; through Jesus Christ our Lord, who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.
