O God, who in the foreknowledge of thy Son's most precious death didst consecrate for him a dwelling-place by the spotless Conception of the Blessed Virgin: mercifully grant that she who was preserved from all defilement may evermore pray for us until we attain unto thee in purity of heart; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end. Amen.
Great post!
