The following two prayers are designated for laity and are derived from the full prayers in the Breviary that date back to at least the 9th century but are likely of a considerably earlier origin as they are similar to prayers found during the 4th century. These prayers are to be said aloud before after after each meal and are to be led by the head of the table.
Prayer Before Meals / Benedic, Domine
Benedic, Domine, nos et haec tua dona quae de tua largitate sumus sumpturi, per Christum Dominum nostrum. Amen.
Bless us, O Lord, and these Thy gifts which we are about to receive from Thy bounty, through Christ, Our Lord. Amen.
Prayers After Meals / Agimus Tibi Gratias
Agimus tibi gratias, omnipotens Deus, pro universis beneficiis tuis, qui vivis et regnas in saecula saeculorum. Fidelium animae, per misericordiam Dei, requiescant in pace. Amen.
We give Thee thanks for all Thy benefits, O Almighty God, Who livest and reignest forever. And may the souls of the faithful departed, through the mercy of God, rest in peace. Amen.
