Mary as co-Redemptrix with Christ.
Mary as co-Mediatrix with Christ.
Mary as perpetually virgin.
Mary remaining without sin for her entire earthly life.
Each can be Clearly refuted by using Scripture.
None of these are contrary to Scripture, but I’m guessing that your basis for saying this about Mary as Co-Mediatrix comes from 1 Tim 2:5:
1 Tim 2:5: “For there is one God, and there is *one mediator *between God and men, the man Christ Jesus…”
Similar arguments are used against Mary as Co-Redemptrix. So, as Catholics, we are told that Mary as Co-Mediatrix is counter to Scripture because this verse says that Jesus is the only mediator. However, just as in many other passages of Scripture, reading and interpreting literally is not accurate.
There were instances in the Old Testament where Abraham, Moses, and Job clearly interceded on behalf of others… that’s mediating between God and man. Scripture cannot contradict itself, so how do we reconcile this with 1 Tim 2:5? Also, we know that it is okay to ask others here on earth to pray for us… that’s mediating between God and man. This is another passage that is convenient for non-Catholic Christians to misinterpret and slam Catholic beliefs, so they do.
There is only one mediator between God and man, the man Jesus Christ, but as members of the Body of Christ, He allows us to share in His mediation.
Also, Scripture tells us that we have only one foundation, Jesus Christ (1 Cor 3:11); but, Scripture tells us that there is more than one foundation (Eph 2:19-20). Scripture tells us that we have only Lord, Jesus Christ (Eph 4:4-5); but, Scripture tells us there is more than one lord (Rev 19:16). Scripture tells us that we have only one Judge, Jesus Christ (James 4:12); but, Scripture tells us there is more than one judge (1 Cor 6:2).
Contradictions in Scripture? No! Not when these passages are all properly understood in context. Catholics take the totality of Scripture into account, not just specific verses that “prove” something we want to say. Jesus is the only foundation; Jesus is the only Lord; and Jesus is the only Judge. But, we are members of Jesus’ Body. Therefore, we are able, according to the graces given by Christ, to share in Jesus’ role as foundation, as lord, and as judge, and in other aspects of Christ, as well.
Another example, as a father I share in God’s role as Father, by His grace. This doesn’t make me equal to God the Father, as I am only sharing in this Fatherhood that He established because He lets me (God the Father set up the family and fatherhood to work this way). So also with Mary; she shares in Christ’s role as redeemer and mediator because He allows her to, not because she is equal to Jesus (indeed she is not, she is a creature created by God) or in some other way has earned God status. Her capacity in these roles is to bring people to her Son, not to herself. Similarly, we and the saints and angels in Heaven can share in Christ’s role as Mediator by bringing others to Him.
I’ve heard this analogy used before, and it made a lot of sense to me. Say a mother is going to bake a cake. She has all the ingredients out and is ready to go when her daughter comes in and asks “Mom, can I help you make the cake?”. The mother says “yes”, and they make it together. The mother didn’t say “yes” because she needed the daughter’s help or couldn’t do it without her. By saying yes, the mother allowed the daughter to share in the process. Same idea with Mary’s role; she is not equal to God. Every power/role she has was given to her by God because of His grace, not any merit of her own. Jesus was Mary’s savior, too.
So again, I say, the ideas of Mary as Co-Mediatrix and Co-Redemptrix are not counter to Scripture. These ideas are, however, very misunderstood among non-Catholics. They cannot be directly found in Scripture, but you yourself told me that this alone doesn’t make them counter to Scripture.
