Collect of the Immaculate Conception of the Blessed Virgin Mary

O God, who by the Immaculate Conception of the Virgin didst prepare a worthy dwelling for Thy Son; we beseech Thee that, as by the foreseen death of that same 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 Christ our Lord. Amen.
