Read this verse from the Bible...
No man can by any means redeem his brother,Or give to God a ransom for him--
For the redemption of his soul is costly,
And he should cease trying forever- - Psalm 49:7-8
now read the Catholic teachings from the Catholic catechism that contradict...
Being obedient she became the cause of salvation for herself and for the whole human race .... CCC 494
This union of the mother with the Son in the work of salvation is made manifest from the time of Christ's virginal conception up to his death. . . .
This ties into this false teaching in the Catholic church...
2027 No one can merit the initial grace which is at the origin of conversion. Moved by the Holy Spirit, we can merit for ourselves and for others all the graces needed to attain eternal life, as well as necessary temporal goods.
No man by any means can redeem his brother!
I am surprised they have not named Mary "Co-Redemptrix" yet, talk about blasphemy against God. There is a movement in the Catholic church to have a FIFTH Marian doctrine named where "Mary" [Rome's false queen of heaven] would be named "Co-Redemptrix". While this belief has not been made "official" the title is used already by the Popes and all over the place in the Catholic church.
Benedict XV, Inter Sodalicia, 1918:
"To such extent did Mary suffer and almost die with her suffering and dying Son; to such extent did she surrender her maternal rights over her Son for : man's salvation . . that we may rightly say she redeemed the human race together with Christ."
Plus XI, 1935, in a prayer to close a jubilee, we find the first use of the word Coredemptrix by a pope:
"O Mother of love and mercy who, when thy sweetest Son was consummating the Redemption of the human race on in the altar of the cross, didst stand next to him suffering with him as a Coredemptrix."
Pope John Paul II at a speech in Ecuador in 1985:
"Having suffered for the Church, Mary deserved to become the Mother of all the disciples of her Son, the Mother of their unity....In fact, Mary's role as Co-redemptrix did not cease with the glorification of her Son"
One thing they claim is that 'co' does not mean partnership but only "with" to muddy the waters but lets not forget that Redemptrix is merely the female form of the word Redeemer.
