The Catholic Defender: Immaculate Conception of the Blessed Virgin Mary


The Blessed Virgin Mary was, by the singular grace and privilege of Almighty God, and in view of the merits of Jesus Christ, Savior of Mankind, kept free from all stain of original sin.


In 1854, Pius IX solemnly proclaimed: “The most Blessed Virgin Mary, in the first instant 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.”


It took a long time for this doctrine to develop. While many Fathers and Doctors of the Church considered Mary the greatest and holiest of the saints, they often had difficulty in seeing Mary as sinless—either at her conception or throughout her life. This is one of the Church teachings that arose more from the piety of the faithful than from the insights of brilliant theologians. Even such champions of Mary as Bernard of Clairvaux and Thomas Aquinas could not see theological justification for this teaching.


Two Franciscans, William of Ware and Blessed John Duns Scotus, helped develop the theology. They pointed out that Mary’s Immaculate Conception enhances Jesus’ redemptive work. Other members of the human race are cleansed from original sin after birth. In Mary, Jesus’ work was so powerful as to prevent original sin at the outset.


In Luke 1:28 the angel Gabriel, speaking on God’s behalf, addresses Mary as “full of grace”. In that context, this phrase means that Mary is receiving all the special divine help necessary for the task ahead. However, the Church grows in understanding with the help of the Holy Spirit. The Spirit led the Church, especially non-theologians, to the insight that Mary had to be the most perfect work of God next to the Incarnation. Or rather, Mary’s intimate association with the Incarnation called for the special involvement of God in Mary’s whole life.


The logic of piety helped God’s people to believe that Mary was full of grace and free of sin from the first moment of her existence. Moreover, this great privilege of Mary is the highlight of all that God has done in Jesus. Rightly understood, the incomparable holiness of Mary shows forth the incomparable goodness of God.


The first thing we must know about our Immaculate Mother is that she needed a Savior, just as all humans do. Her Savior is her Son, just as He is our Savior.
