Who is the Immaculate Conception?

The Immaculate Conception refers to the belief in the Roman Catholic Church that Mary, the mother of Jesus, was conceived without original sin. This doctrine asserts that from the moment of her conception, she was preserved by God's grace to be a pure vessel for the birth of Christ. The celebration of the Immaculate Conception is observed on December 8th each year. It is important to note that this doctrine is about Mary's conception, not the conception of Jesus.
