I don’t think reiterating helps you at all.
“This means 0 established denominations that my opponent can refer to, back the idea. Furthermore, the idea is anti-Christian. It elevated his earthly mother to a role she never achieved.”
It is ridiculous to make the claim that this is not historical. St. Irenaeus called Mary the “cause of salvation.”
The idea is not anti-Christian because it points to Christ.
“A co-redemptrix would need to redeem us from something. My opponent's sole focus is some old testament prophecies about some heel or whatever. Even if Mary is somehow the antithesis of Eve, which I grant is plausible to argue. It doesn't mean that she co-redeemed us. In no shape or form did she herself redeem us. The only way to argue this is to say that all mother's are to be genuinely held responsible for achievements of their offspring.”
She played a role in redemption. She brought forth the redeemer in this world. No one else has ever come close to such. She doesn’t directly redeem us. That’s why she’s called co-redemptrix.
These Old Testament verses show what “blessed among women means.” They are used when referring to women who defeated the enemy in war. The devil is the ultimate enemy, and Mary plays a role in Jesus’ defeating Satan.
Mary was seen as the New Eve from the very beginning. St. Justin Martyr, St. Irenaeus, and Tertullian made this connection:
[Jesus] became man by the Virgin so that the course which was taken by disobedience in the beginning through the agency of the serpent might be also the very course by which it would be put down. Eve, a virgin and undefiled, conceived the word of the serpent and bore disobedience and death. But the Virgin Mary received faith and joy when the angel Gabriel announced to her the glad tidings that the Spirit of the Lord would come upon her and the power of the Most High would overshadow her, for which reason the Holy One being born of her is the Son of God. And she replied ‘Be it done unto me according to your word’ [Luke 1:38]” (Dialogue with Trypho the Jew 100 [A.D. 155]).
Thus, the knot of Eve’s disobedience was loosed by the obedience of Mary. What the virgin Eve had bound in unbelief, the Virgin Mary loosed through faith” (Against Heresies 3:22:24 [A.D. 189]).
It was while Eve was still a virgin that the word of the devil crept in to erect an edifice of death. Likewise through a virgin the Word of God was introduced to set up a structure of life. Thus what had been laid waste in ruin by this sex was by the same sex reestablished in salvation. Eve had believed the serpent; Mary believed Gabriel. That which the one destroyed by believing, the other, by believing, set straight” (The Flesh of Christ 17:4 [A.D. 210].
“Neither of these are relevant. Proving that the word save in a translation to English is used in a lesser way than Christ saving us from sin is irrelevant to the debate. Unless my opponent is claiming the extreme heresy and basically blasphemy that all husbands and wives save each other from sin how Yeshua the Christ did or even close to what he did, my opponent has no case at all.”
I don’t think this is about English translations. The Greek word is sózó. The NASB gives the word many different meanings depending on context: “bring...safely (1), cured (1), ensure salvation (1), get (1), get well (2), made...well (6), made well (5), preserved (1), recover (1), restore (1), save (36), saved (50), saves (1), saving (1).”
It can mean many things. Saying Mary saves us cannot be called heresy. Does faith save? “But I thought only God saved.” We are saved through faith (and works) by the grace of God.
“Firstly, a good counterargument is that in some ways the archangels are above her and this gets forgotten by Catholic somehow, that a human cannot be above archangels like St. Michael or St. Gabriel. Nonetheless, even if she's got the title 'Queen of Heaven' her role was never redeeming us of sin.”
Catholics never considered the angels to be greater than Mary. They didn’t forget anything. Mary is the Mother of God. Angels are servants and messengers of God. Angels bring God’s word, but Mary brought forth the Word (Logos) in the flesh.
In the Byzantine Catholic Liturgy Mary is called more honorable and glorious than the cherubim and seraphim. They are the highest ranking angels but do not compare to Mary:
It is truly proper to glorify you - O Theotokos, - the ever-blessed, immaculate, and the Mother of our God. - More honorable than the cherubim, - and beyond compare, more glorious than the seraphim; - who a virgin, gave birth to God the Word, - you truly the Theotokos - we magnify.
Mary is Queen of Heaven because Jesus is King of Heaven. Look in the Bible and you will find the queen is the mother of the king (1 Kings 2:18-19, 2 Chronicles 22:10). You will see the queen even makes intercessions (Nehemiah 2:6).
Con never even gave us a single Bible verse to back up his arguments. I’ll suspect this one may be used:
For there is one God, and one mediator of God and men, the man Christ Jesus (1 Timothy 2:5)
Many try to use this verse to disprove the idea of co-redemptrix, but we need to look at the context in the next verse:
who gave himself as a ransom for all people. This has now been witnessed to at the proper time.
It’s about redemption. Obviously, Mary couldn’t die on the cross. This is why she is co-redemptrix and not redemptrix.
And the verses before show about intercession of saints. The “one mediator” needs to be put into context. God uses people to do things:
I desire therefore, first of all, that supplications, prayers, intercessions, and thanksgivings be made for all men: For kings, and for all that are in high station: that we may lead a quiet and a peaceable life in all piety and chastity. For this is good and acceptable in the sight of God our Saviour
Finally, back to the title:
“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.” - Wikipedia
Do you deny that Mary did this?
"Ave Maria, gratia plena, Dominus tecum; Benedicta tu in mulieribus, et benedictus fructus ventris tui, Iesus. Sancta Maria, Mater Dei, ora pro nobis peccatoribus, nunc et in hora mortis nostrae. Amen."
