> The Immaculate Conception, according to the teaching of the Catholic Church, was the conception of the Blessed Virgin Mary in her mother's womb free from original sin by virtue of the foreseen merits of her son Jesus Christ.
The Immaculate Conception is commonly confused with the doctrine of the Incarnation and the virgin birth of Jesus, though the two deal with separate subjects. The Catholic Church teaches that Mary was conceived by normal biological means, but her soul was acted upon by God (kept "immaculate") at the time of her conception.
