The Concluding Prayer of the Church
Almighty God, who after the creation of the world rested from all your works and sanctified a day of rest for all your creatures: Grant that I, putting away all earthly anxieties, may be duly prepared for the service of public worship, and grant as well that my Sabbath upon earth may be a preparation for the eternal rest promised to your people in heaven; through Jesus Christ our Lord.
