The Church holds that there is no further revelation after Christ. Christ is the fulfillment of revelation, closing the loop on everything, and tying together the myriad threads of theology woven in the history of Israel. While there is nothing new to be revealed, what has occurred over the centuries of Church history is a more in-depth understanding of what has already been shared. A reaffirming principle of theology is that simple ideas and words have a depth to them that unpacking them can take centuries.

No place is the more true than Mariology. Mary’s place of honor in the Church is a natural and logical outflow of her place in Jesus’ life. What man doesn’t love his mother? If Christ bears this love for His mother, shouldn’t the Church, His body, do the same? But understanding her uniqueness in human history, and the philosophical properties attributable to this status requires deep thought and clarification.

When you look at the list of Vatican-approved Marian apparitions, the circumstances of them is astounding. These approved apparitions were studied and scrutinized, and their effects observed before receiving the seal of approval. These sixteen or so apparitions have similar threads. From France and Belgium, to Japan, Ireland, Venezuela, Rwanda, and Mexico, Mary appears dressed in a culturally appropriate attire and speaks the language of the people. This is the style of a mother looking to connect with her child, not a regent arriving to condescend. Our understanding of her role as mother not just to Jesus, but to His Body, is furthered by this subtle communication.

The same is true for the theological dogma that is not just proclaimed, but solemnly celebrated today: the Immaculate Conception. Although Mary lived in the first century, it wasn’t until the 1854 that the Church proclaimed the dogma that Mary was conceived without original sin. That’s a long time to contemplate the idea, but it’s a conclusion that is not only logical, but imperative.

Original sin is the stain passed from parent to child that is at the root of our fallen nature, but its remedy is often obtained by those same parents: Baptism. Each time we receive the Eucharist, we bring the completeness of Christ within our physical selves. Though it lasts only a moment, that interaction changes us. How can we not be changed when imperfection comes into concrete contact with perfection? But when we receive the Eucharist, He only physically dwells in us for a few minutes before the digestive process is complete.

Christ’s human gestation was entirely normal, nine months in utero of growth and development. How could it be that perfection would physically dwell in imperfection for that long of a time? Further, how could Mary be prepared for the weight of her vocation if there was even the smallest idea of disobedience somewhere in her conscience? That is why the Immaculate Conception is so theologically significant, and necessary. At the moment Mary was created, she was spared the stain of sin. This was not to pigeonhole her into fiat, but so that if she chose to entrust herself fully to God, that when the magnificent and imposing presence of an archangel appeared to her, she would be totally free to respond.

The layers of Mariology are still being explored and unpacked, but today is a little reminder of just how incredible she is, and how lucky we are to call her Mom.
