965 After her Son's Ascension, Mary "aided the beginnings of the Church by her prayers."504 In her association with the apostles and several women, "we also see Mary by her prayers imploring the gift of the Spirit, who had already overshadowed her in the Annunciation."505
. . . also in her Assumption
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."506 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.507
. . . she is our Mother in the order of grace
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."
It's there. I tend to use the one on the vatican website since it has https protocols, the borneo one doesn't. Here is a safer link for the catechism.
