A title of the Blessed Virgin as co-operator with Christ in the work of human redemption. It may be considered an aspect of Mary's mediation in not only consenting to become the Mother of God but in freely consenting in his labors, sufferings, and death for the salvation of the human race. As Co-Redemptrix, she is in no sense equal to Christ in his redemptive activity, since she herself required redemption and in fact was redeemed by her Son. He alone merited man's salvation. Mary effectively interceded to obtain subjective application of Christ's merits to those whom the Savior had objectively redeemed.
