As Jesus was saying these things, a woman in the crowd called out, 'Blessed is the mother who gave you birth and nursed you.' He replied, “Blessed rather are those who hear the word of God and obey it. I want you to read this carefully, please. Jesus gives us clear instructions on how and whom to pray to. He does not, at any point, tell us that prayers from the deceased, even if they're in heaven, are possible. Prayer is your way to approach and speak to Christ, to get to speak to him and know him in conjunction with his word in the bible. The passages you linked are members of the early church and other brothers and sisters in Christ asking for other living members of the body to pray in their behalf. At no point do they ask the deceased, even those in heaven, to pray for them. At no point did I imply Mary was dead and gone, you're twisting my words. I have no doubt she is in heaven and holds a place amount the great prophets like Moses, Ezekiel, David, and John. But prayer to her detracts from a person's focus which should be on Father and his Son. I won't say Catholics are not saved. But their prayers to the dead saints and Mary amount to a modern form of idolatry because you're engaging in a personal conversation with someone other than whom you should be.
