You're right and it amazes me that through ignorance of the Bible catholics can be led so far astray.
969. "'This motherhood of Mary in the order of grace continues uninterruptedly from the consent which she loyally gave at the Annunciation and which she sustained without wavering beneath the cross, until the eternal fulfilment of all the elect. Taken up to heaven she did not lay aside this saving office but by her manifold intercession continues to bring us the gifts of eternal salvation .... Therefore the Blessed Virgin is invoked in the Church under the titles of Advocate, Helper, BENEFACTRESS, and MEDIATRIX.
509. "Mary is truly 'MOTHER of GOD' since she is the MOTHER of the eternal Son of GOD made man, who is GOD himself."
963. "Since the Virgin Mary's role in the mystery of Christ and the Spirit has been treated, it is fitting now to consider her place in the mystery of the Church. 'The Virgin Mary . . . is acknowledged and honored as being truly the MOTHER of GOD and of the redeemer.... She is 'clearly the MOTHER of the members of Christ' ... since she has by her charity joined in bringing about the birth of believers in the Church, who are members of its head.'[LG 53; cf. St. Augustine, De virg. 6: PL 40,399.] 'Mary, MOTHER of Christ, MOTHER of the Church.'[Paul VI, Discourse, November 21,1964.]"
To view the context, please visit http://www.christusrex.org/www1/CDHN/church6.html#Mary 966. "'Finally the Immaculate Virgin, preserved free from all stain of original sin, when the course of her earthly life was finished, was taken up body and soul into heavenly glory, and exalted by the Lord as Queen over all things, so that she might be the more fully conformed to her Son, the Lord of lords and conqueror of sin and death.'[LG 59; cf. Pius XII, Munificentissimus Deus (1950): DS 3903; cf. Rev 19:16.] The Assumption of the Blessed Virgin is a singular participation in her Son's Resurrection and an anticipation of the resurrection of other Christians:
In giving birth you kept your virginity; in your Dormition you did not leave the world, O MOTHER of GOD, but were joined to the source of Life. You conceived the living GOD and, by your prayers, will deliver our souls from death.[Byzantine Liturgy, Troparion, Feast of the Dormition, August 15th.]"
Matthew 12:46 As Jesus was speaking to the crowd, his mother and brothers were outside, wanting to talk with him.
Matthew 12:47 Someone told Jesus, “Your mother and your brothers are outside, and they want to speak to you.”
Matthew 12:48 Jesus asked, “Who is my mother? Who are my brothers?”
Matthew 12:49 Then he pointed to his disciples and said, “These are my mother and brothers.
Matthew 12:50 Anyone who does the will of my Father in heaven is my brother and sister and mother!”
MARK 3:31 Jesus’ mother and brothers arrived at the house where he was teaching. They stood outside and sent word for him to come out and talk with them.
MARK 3:32 There was a crowd around Jesus, and someone said, “Your mother and your brothers and sisters£ are outside, asking for you.”
MARK 3:33 Jesus replied, “Who is my mother? Who are my brothers?”
MARK 3:34 Then he looked at those around him and said, “These are my mother and brothers.
MARK 3:35 Anyone who does God’s will is my brother and sister and mother.”
LUKE 11:27 As he was speaking, a woman in the crowd called out, “God bless your mother—the womb from which you came, and the breasts that nursed you!”
LUKE 11:28 He replied, “But even more blessed are all who hear the word of God and put it into practice.”
Jesus made it clear that Mary wasn't greater than any other Christian.
