O God the Father,
fountain and source of all goodness,
in your loving-kindness you sent
your only Son into the flesh.
We thank you that for his sake
you have given us pardon and peace in this Sacrament.
We pray that you will not forsake your children,
but always rule our hearts and minds
by your Holy Spirit,
that we may constantly serve you;
through Jesus Christ, our Lord,
who lives and reigns with you and the Holy Spirit,
one God, now and forever.

Original in Latin:
DEUS Pater, fons et origo totius bonitatis, qui ductus misericordia Unigenitum tuum pro nobis ad infima mundi descendere et carnem sumere voluisti, quam ego indignus hic in manibus meis teneo:
Hic inclinet se sacerdos ad hostiam, dicens:
Te adoro, te glorifico, te tota mentis ac cordis intentione laudo: Et precor ut nos famulos tuos non deseras, sed peccata nostra dimittas, quatenus tibi soli vivo ac vero Deo, puro corde et casto corpore servire valeamus; Per eundem Christum Dominum nostrum. Amen.
Translation of the unmodified Latin prayer in traditional English:
O God the Father, Fountain and Source of all goodness, Whose mercy willed that Thy only begotten Son should descend to this lower world for us, and should take upon Him flesh, which I unworthy hold here in my hands, saying, I adore Thee, I glorify Thee with every power of my heart, I praise Thee, and I pray that Thou wilt not leave us, Thy servants, but forgive us our sins, so far as we deserve to serve Thee, the only living and true God, with pure heart and chaste body, through the same Christ our Lord. Amen.
