On this feast of the Immaculate Conception we are celebrating the redemption of Mary by Jesus. By God's power the effect of the redeeming death of Jesus was applied to Mary, in anticipation, at the moment of her conception. The Immaculate Conception is all about the redemptive power of the Paschal Mystery. Mary's redemption involves preservation from sin. The rest of humanity is cleansed from sin. Mary's privilege is rooted in her divine maternity and is a call for us to praise and thank God.
