Today we celebrate the Feast of the Immaculate Conception. We proclaim and believe that God, in His goodness and love, preserved Mary from all stain of sin from the moment of her conception -- thus preparing her to be a worthy vessel for God's Son. In this liturgy we adore our God and thank God for the redemption of the world, wrought by the death and resurrection of His Son. May we, like Mary, strive for holiness and purity, so that we also may constantly say "Yes" to our God.
