The icon of the Annunciation, more than any other, helps us to see clearly how everything in the Church goes back to that mystery of Mary's acceptance of the divine Word, by which, through the action of the Holy Spirit, the Covenant between God and humanity was perfectly sealed. Everything in the Church, every institution and ministry, including that of Peter and his Successors, is "included" under the Virgin's mantle, within the grace-filled horizon of her "yes" to God's will.

Benedict XVI
