Co-Redemptrix
Co-Redemptrix (also spelled Coredemptrix; Co-Redemptress is an equivalent term) is a title used by some Catholics for the Virgin Mary, emphasizing her unique, subordinate cooperation with Jesus Christ in the redemption of humanity. According to those who use the term, Co-Redemptrix refers to a subordinate but essential participation by the Blessed Virgin Mary in redemption, notably that she gave free consent to give life to the Redeemer, which meant sharing his life, suffering, and death, which were redemptive for the world.
