J.M.J. The astonishing action of God in protecting Our Blessed Lady from the audacious and reckless sin of our first parents Adam and Eve occurred precisely at the first moment of her conception. When Mary’s father Joachim and mother Ann provided the human matter necessary for conception, the Lord, as He always does, infused the soul that would coalesce with the human ingredients to form Mary. And when the beneficent Creator did so, He ensured that Mary would never experience even the slightest stain of Original Sin.
What God did for the very young Mary underscores the fact that human life does begin at conception. Our Blessed Mother was not preserved from Original Sin before she came to be. Exactly when her existence began God worked His miracle that we gladly cherish and refer to as the “Immaculate Conception.”
We gain much whenever we mull over the challenging, reasonable tenets of our Catholic Faith. The Dogma of the Immaculate Conception is no exception. By meditating on and striving to penetrate what God did for Mary, we obtain fresh insights into the Lord’s goodness, the Virgin's holiness and human life's beauty and splendor even in its preborn state.
