The fifth session of the Council of Trent (1546) laid out the belief in Jesus the one true mediator as the norm of Catholic faith: "[Original sin cannot be] taken away through the powers of human nature or through a remedy other than the merit of the one mediator, our Lord Jesus Christ, who reconciled us to God in his blood, having become our justice, and sanctification, and redemption."
1. in suffering with him -- so, she suffered alongside him -- His suffering and sacrifice is what saved us
2. She co-operated in the work -- so too do you co-operate with Christ when you pray and follow His gospel
3. you need to link "this saving function, " with the this referred which is "This motherhood of Mary in the economy of grace"
4. "but by her manifold intercession," contains the same significance as you interceeding with God for someone else, as in you praying to God for someone else
5. "she continues to win the gifts" -- note: She wins it. From whom? From God, from the Sole Mediator between sinful humanity and righteous God -- her Son, Our Lord and God, Jesus Christ.
Yes, I have heard the same vatican double speak for some time now. "She's a Mediatrix while Jesus is the sole Mediator; She's a co-redemptrix while Jesus is the only redeemer; All graces flow thru Mary and Jesus is the source of all grace."
The RC Mary seems to posess many attributes of deity in her ability to hear and grant prayers.
My Father likes to say she has the ability to soften Jesus Judgement of us, because he cannot refuse His mother so we can take refuge in her.
While this is certainly a heart warming, familial depiction, it is quite anti biblical.
