On the anniversary of the issuance of the Apostolic Letter Given Motu Proprio “Summorum Pontificum” on the Use of the Roman Liturgy Prior to the Reform of 1970, by Pope Benedict XVI (7 July 2007), for which we offer this prayer:

Our God and Savior Jesus Christ, we thank You for giving us Summorum Pontificum through Your faithful vicar Benedict, who thus affirmed and strengthened our liberty to celebrate the living Forms of the Roman Rite. Grant that we, who are nourished by the liturgy and tradition of Your Body the Church, may be ever filled with Your grace and truth, that we might remain in Your love until death and dwell with You forever in heaven. Amen.
