Mary was just a righteous woman who gave birth to Jesus. Jesus existed eternally with God the Father before he was born as a baby on earth. Mary isn't the mother of God. Mary never wrote scripture. Jesus discouraged people from giving her any special honor. Mary can't hear you when you pray to her. She has no message for anyone except to accept Christ as Savior and Lord. Anyone can receive Christ. Nobody receives Christ through Mary. The Satanists in charge of the Catholic Church have made Mary into an idol, a false goddess. I'm sure that the real Mary is appalled.
There's no way your message is from Mary. You're either lying or insane or in contact with demons. Those are the only possible choices.
