Although the Dismissal marks the real conclusion of the Mass, it is followed by a private farewell prayer of the celebrant, followed by a kissing of the altar and (except for Masses for the dead) a blessing of the congregation:
Placeat tibi, sancta Trinitas, obsequium servitutis meae: et praesta ut sacrificium, quod oculis tuae Majestatis indignus obtuli, tibi sit acceptabile mihique et omnibus, pro quibus illud obtuli, sit, te miserante, propitiabile. Per Christum Dominum nostrum. Amen.
May the homage of my bounden duty be pleasing to you, O holy Trinity; and grant that the sacrifice which I, though unworthy, have offered in the sight of your majesty may be acceptable to you and through your mercy be a propitiation for me and for all those for whom I have offered it. Through Christ our Lord. Amen.
Benedicat vos omnipotens Deus, Pater et Filius ✠ et Spiritus Sanctus.
r. Amen.
May almighty God bless you, the Father, the Son ✠ and the Holy Spirit.
r. Amen.
