[Nihil Obstat]

as Inigo Montoya said: "You keep using that word. I do not think it means what you think it means."

English and latin don't mix that well. "co-" does not mean equal to in any way at all. I'm sure you've been told that many times.

Yes, I've been told that several times especially in the veneration of Mary. Just so there is no confusion as to what co-redemption means below is an excerpt from MARY Coredemptrix Mediatrix Advocate.

As Father Louis Bouyer, the famous Lutheran pastor who became a Catholic and even a Catholic priest and theologian, stresses, our free consent to salvation is a gift of God’s grace (Aquinas, Summa Theologica I.II.112.3): a great mystery which means that God is the Creator and Master of our freedom itself, operating inside this freedom.

This is particularly true about Mary’s consent to our Redemption by the Son of God, consent given in our name. Mary’s coredeeming consent results from his action inside her freedom. Without God’s cooperating grace (Aquinas, Summa Theologica, I.II.III.2), Mary could not have consented to our salvation; but we could not consent to our own salvation without Mary’s previous consent to the Redemptive Incarnation for the love of mankind. Thus Mary’s consent, given under the form of a prayer (Lk 1,38), is a prayer obtaining from God our consent to our salvation by Jesus Christ.

In other words it is through her work and generosity that salvation came into the world because she consented for mankind to be saved through the birth of God's Son.
