You didn't get that from scripture...Obviously your religion made that up and now you state it as fact, with not an iota of evidence...
She may only dispense the Grace that comes FROM God.
Do you guys go into a trance when you get baptized into your religion??? Perhaps you all have been hypnotized...Mary doesn't dispense any grace from anyone...Why do you spew this stuff???
She does not redeem you from sin.
But yet you call her your co-redeemer...Your co-mediator...
What, the idea that the saints in heaven hear our prayers, or the idea that the saints in heaven hear our prayers through the power of God?
The idea that the saints in heaven hear our prayers and intercede for us is clear from 2 Maccabees 15:14 (not our fault that that book was taken away from your Bible) and many other passages, including:
Matt 17:1-3 Jesus converses with Moses and Elijah at the Transfiguration
Matt 26:53 Jesus says he can call on 12 legions of angels. If he can, so can we. Additionally, he says in Matt 22:30 that the saints in heaven are like angels. Therefore, we can call on them, too.
Rev 5:8 The prayers of the faithful on earth are presented to God by the angels and saints in heaven
Rev 8:3-4 The prayers of the faithful are presented to God by an angel
There many other examples. Also, it only stands to reason that, if we pray for each other on earth because we love each other, when we are in heaven where our love is perfected by God, we will then pray for each other, not less, but perfectly.
As for Mary hearing prayers through God's grace and power, not her own, why should Cronos need Scripture to prove that God is in control and everything happens through Him? Don't you believe that as well?
But yet you call her your co-redeemer...Your co-mediator...
The title is "Mediatrix of all Grace," not "co-mediator".
All grace comes through Mary because all grace comes through the Incarnation of Jesus Christ, which came through Mary. Seems rather obvious.
"Co-Redemptrix" ("co" is a Latin prefix meaning "with," not "equal to") merely means that Mary coöperated in the Redemption in a unique way, mirroring Eve's coöperation in the Fall. That's obvious from Scripture; the rest of us don't have angels appearing to us announcing that we are to become the mother of the Messiah.
Neither of those two titles are taught as dogmatic truth by the Church.
