VIVERE CHRISTUS EST I SOLEMNITY OF THE IMMACULATE CONCEPTION OF THE BLESSED VIRGIN MARY I DECEMBER 08

O God, who by the Immaculate Conception of the Blessed Virgin

prepared a worthy dwelling for your Son, grant, we pray, that, as you preserved her from every stain by virtue of the Death of your Son, which you foresaw, so, through her intercession, we, too, may be cleansed and admitted to your presence.

Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, God, for ever and ever.
