The Blessed Virgin Mary, preserved from all stain, a worthy dwelling for the Son of God

O God, who by means of the Immaculate Conception of the Virgin didst prepare a worthy dwelling for thy Son, and foreseeing his death, didst thereby preserve her from all stain, grant that we too by her intercession may come to thee unstained by sin: through the same Jesus Christ, thy Son, our Lord, who is God, living and reigning with thee, in the unity of the Holy Spirit, for ever and ever. Amen.

Deus, qui per immaculátam Vírginis Conceptiónem dignum Fílio tuo habitáculum praeparásti: quáesumus; ut, qui ex morte ejúsdem Fílii tui praevísa, eam ab omni labe praeservásti, nos quoque mundos ejus intercessióne ad te perveníre concédas. Per eúndem Dóminum nostrum Jesum Christum, Fílium tuum, qui tecum vivit et regnat in unitáte Spíritus Sancti, Deus; per ómnia sáecula saeculórum. Amen.
