Glorificamus,
LSP
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 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.
...Do thou, then, O Blessed Mother, our queen and advocate, who from the first instant of thy conception didst crush the head of the enemy, receive the prayers which, united with thee in our single heart, we implore thee to present at the throne of God, that we may never fall into the snares which are laid out for us, and may all arrive at the port of salvation; and, in so many dangers, may the Church and Christian society sing once again the hymn of deliverance and of victory and of peace. Amen.
