In order to enter more deeply into the mystery of the Immaculate Conception, the theologian compares and contrasts this mystery to that of original sin. He compares the fullness of grace implied in this mystery of the Immaculate Conception to Adam and Eve's fullness of grace in original justice, as well as to that of Christ. Finally, to go further and to shed more light on the richness of the mystery, the theologian puts his philosophical knowledge at the service of his faith. Then he can use the various analogies suggested by the mystery itself. He uses the analogies of human motherhood and of contemplation to shed more light on the mystery of Mary's divine motherhood.
Divine motherhood is a mystery of contemplation.
Mary is Mother in the fullness of her faith. In her divine motherhood, she is blessed in her faith. Divine motherhood is also a mystery of real motherhood. We can see all the richness of such research and of such theological contemplation. We could also try to develop a treatise of biblical theology concerning the mystery of Mary.
