Christ was always in the OT and He and God and the Holy Spirit work as one in the trinity. He was always there. I don't know what you're ranting about. I'm saying God through Jesus Christ is the one who answers prayer, not Mary and not the Saints. ONLY GOD. I'm not keen on Mary's visions. I don't know if they are real or satanic in nature. I have no knowledge of them. But only God, His Son, and the Holy Spirit answer our prayers. They are the three-in-one. Mary has no power to do that. Sorry. I know that's what you are taught but I believe that it's GOD, not Mary, much as she is respected for her obedience to God. She's not a miracle worker.
You presume to know quite a lot about what we're taught, don't you? For the record, we are NOT taught that Mary has the power to do that. Intercessory prayer. That's it. The answer comes from God/Christ/Holy Spirit. Mary can and does pray (intercede) for us if we ask her to, but the results come only from the Triune God.
