Collect Prayer of the Feast of Our Lady of Guadalupe

O God, Father of mercies, who placed your people under the singular protection of your Son’s most holy Mother, grant that all who invoke the Blessed Virgin of Guadalupe, may seek with ever more lively faith the progress of peoples in the ways of justice and of peace. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever. Amen.
