O God, Who by the Immaculate Conception of the Virgin
didst prepare a worthy habitation for Thy Son,
we beseech Thee, that as by the foreseen death
of Thy same Son,
Thou didst preserve Her from all stain of sin,
so Thou wouldst grant us also,
through Her intercession
to come to Thee with pure hearts.
Through the same Jesus Christ,
Thy Son, our Lord,
Who liveth and Reigneth with Thee,
in the unity of the Holy Ghost,
one God,
world without end.
Amen
