Mary-- "Blessed is she who believed," ccc 148-149

148 The Virgin Mary most perfectly embodies the obedience of faith. By faith Mary welcomes the tidings and promise brought by the angel Gabriel, believing that "with God nothing will be impossible" and so giving her assent: "Behold I am the handmaid of the Lord; let it be [done] to me according to your word." Elizabeth greeted her: "Blessed is she who believed that there would be a fulfilllment of what was spoken to her from the Lord." It is for this faith that all generations have called Mary blessed.

149 Throughout her life and until her last ordeal when Jesus her son died on the cross, Mary's faith never wavered. She never ceased to believe in the fulfillment of God's word. And so the Church venerates in Mary the purest realization of faith.
