"Placeat Tibi"

Bowing down before the Altar, with hands joined upon it, the Priest says:

PLACEAT tibi, sancta Trinitas, obsequium servitutis meae: et praesta, ut sacrificium quod oculis tuae majestatis indignus obtuli, tibi sit acceptabile, mihique, et omnibus proquibus illud obtuli, sit te miserante propitiabile. Per Christum Dominum nostrum.  Amen.

MAY the performance of my homage be pleasing to Thee, most Holy Trinity: and grant that the Sacrifice which I, though unworthy, have offered up in the sight of Thy Majesty, may be acceptable to Thee, and through Thy mercy, be a propitiation for me and for all whom I have offered it. Through Christ our Lord.  Amen.
