O God,
who by the Immaculate Conception of the Blessed Virgin Mary,
didst prepare a worthy dwelling place for thy Son,
we beseech thee that,
as by the foreseen death of this,
thy Son,
thou didst preserve her from all stain,
so too thou wouldst permit us,
purified through her intercession,
to come unto thee.
Through the same Lord Jesus Christ,
thy Son,
who lives and reigns with thee in the unity of the Holy Ghost,
God, world without end.
Amen.
