About the Immaculate Conception:
The Immaculate Conception is the celebration of Mary’s conception in the womb of her mother St. Anne and occurs exactly 9 months before we celebrate Mary’s birthday on September 8th. Immaculate Conception is a church teaching that says Mary, the Mother of Jesus, was preserved from original sin at the moment of her conception. Mary’s body was created the way all human bodies are, from the generative act of her mother and father. It was Mary’s soul (the gift from God that makes us who we are) that was excluded from original sin by the sanctifying grace of God.
The teaching that Mary was born without sin from the moment of her conception is not specifically mentioned in the Bible but is rooted in scripture. Perhaps the most obvious reference is Luke 1:28 when the angel Gabriel addresses Mary as “full of grace.” In 1854 the church through Pope Pius IX formally defined the teaching of her immaculate conception as dogma (truth).
