Thanks for posting those references from the Catechism of the Catholic Church. You are encouraging others to learn too.
God bless.
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
So you agree then, that the prayers of Mary will deliver people's souls from death?
