Why does Mary, the Mother of Jesus, have such a big place in our church? The words of the angel in Luke’s gospel, words we often repeat in prayer, are an answer: “Hail, full of grace, the Lord is with you.”

Mary is filled with God’s grace, gifted with unique spiritual gifts from her conception, because she was to be the mother of Jesus Christ, God’s only Son.

She would be the “resting place of the Trinity,” and would give birth to, nourish, guide and accompany Jesus in his life and mission in this world. To fulfill that unique role she needed a unique gift. She would be free from original sin that clouds human understanding and slows the way we believe God and his plan for us.

“How slow you are to believe” Jesus said to the two disciples on the way to Emmaus. Jesus made that complaint repeatedly as he preached the coming of God’s kingdom. “How slow you are to believe!” “What little faith you have!” “Do you still not understand!” Human slowness to believe didn’t end in gospel times. We have it too.

Mary was freed from that slowness to believe. “Be it done to me according to your word,” she immediately says to the angel. Yet, her acceptance of God’s will does not mean she understood everything that happened to her. “How can this be?” she asks the angel about the conception of the child. “The Holy Spirit will come upon you.”  But the angel’s answer seems so incomplete, so mysterious.

Surely, Mary would have liked to know more, but the angel leaves, never to return. There’s no daily message, no new briefing or renewed assurance by heavenly messengers. The years go by in Nazareth as the Child grows in wisdom and age and grace, but they’re years of silence. Like the rest of us, Mary waits and wonders and keeps these things in her heart.

That’s why we welcome her as a believer walking with us. She is an assuring presence who calls us to believe as she did, without knowing all. She does not pretend to be an expert with all the answers. She has no special secrets she alone knows. “Do whatever he tells you,” is her likely advice as we ponder the mysteries of her Son.

The feast of the Immaculate Conception is celebrated 9 months before the feast of the Birth of Mary (September 8). The feast  was extended to the universal Church by Pope Clement XI in 1708.

 Pope Pius IX solemnly proclaimed the Dogma of the Immaculate Conception in 1854: “We declare, pronounce, and define that the doctrine which holds that the most Blessed Virgin Mary, in the first instance of her conception, by a singular grace and privilege granted by Almighty God, in view of the merits of Jesus Christ, the Savior of the human race, was preserved free from all stain of original sin” (Ineffabilis Deus, 1854)
