Here's a link to an R.C. site, which claims that Mary is our "Co-redemptrix" and that this assertion comes from the so-called "Magisterium". Needless to say, it's the usual tedious R.C. sophistry.
You'd have to highlight WHERE the CCC states that Mary is a co-redeemer or co-redemptrix.
1. Many Catholics, including myself, use the title
Co-Redemptrix for Mary, but the term is often misunderstood. "Co-" comes from the Latin
cum ("with"), not "equal to." The title is meant to express Mary's unique cooperation with Christ's saving mission, not equality with Jesus.
2. Supporters point to Mary's free "yes" at the Annunciation (Luke 1:38), Her lifelong cooperation with God's plan, and Her presence at the foot of the Cross as reasons She participated in a unique way in the work of redemption.
3. In this view, Jesus alone is the Redeemer. Mary's role is entirely dependent on Him and subordinate to Him. Advocates argue that "Co-Redemptrix" means She cooperated
with the Redeemer, not that She redeemed humanity Herself.
4. The Catholic Church teaches that Mary cooperated in salvation history, but it has never defined "Co-Redemptrix" as a dogma. The Second Vatican Council preferred language about Mary's cooperation while carefully preserving Christ's unique role as Savior.
5. This is one reason the word does not appear in the
Catechism of the Catholic Church. The Catechism teaches Mary's cooperation and spiritual motherhood, but it does not use the title itself.
6. Another reason is that the title can be misunderstood. Many hear "Co-Redemptrix" and assume it means Mary is an equal partner with Christ in redemption, which is not what its defenders mean.
7. Debate over the title has existed for decades. Some theologians and bishops supported defining it as a Marian dogma, while others argued the term creates confusion and can obscure Christ's unique role.
8. In 2025, the Vatican's Dicastery for the Doctrine of the Faith stated that the title
Co-Redemptrix is not an appropriate way to describe Mary's participation in salvation because it risks eclipsing the exclusive role of Jesus Christ as Redeemer.
9. The Vatican document reaffirmed that Mary has a unique cooperation in God's plan of salvation, but emphasized that Christ alone is the sole Mediator and Redeemer.
10. So the short answer: Catholics who use the title
Co-Redemptrix mean that Mary uniquely cooperated with Christ's saving work. The title is not in the Catechism because the Church has never formally adopted it there, and concerns have long existed that the term can be misunderstood or appear to diminish Christ's unique role as Redeemer.
Personally, I find the title
Co-Redemptrix or
Co-Redeemer entirely fitting for Mary. The term does not mean that She is equal to Christ, but rather that She cooperated
with Him in the work of redemption. Her cooperation began with Her fiat at the Annunciation and continued through Her giving birth to the Savior, raising Him, and remaining faithful at the foot of the Cross. As Simeon prophesied, "
and a sword will pierce your own soul also," Mary willingly accepted this suffering in union with Her Son. Because of this unique cooperation in salvation history, I believe the title accurately reflects Her role.
Additionally, in a broader sense, all Christians are called to cooperate in Christ's redemptive work. Through prayer, sacrifice, suffering united to Christ, and acts of charity, we help bring souls closer to God. In that sense, Mary's cooperation is unique and unparalleled, but it is not entirely unlike the way believers are invited to participate in God's plan of salvation.
