I know! I know!
A. There is no record of Mary being alive in Heaven.
B. Jesus rebuked her when she tried to intervene. He never showed any inclination or definition (in Scripture) that she was anything more than His birth vessel!
Why would Jesus listen to His mother when His Father is God? Surely you can't compare Mary to God, can you? That is ridiculous, and blasphemous. God is all powerful, all knowing, and ever present. The Biblical Mary is none of these. She's dead and waiting with those others who are dead and waiting to be alive again in Christ (contrary to Roman Catholic mythology)!
But then, the Roman Catholic mary is not the one we see in Scripture! That ones demands attention to herself and only insinuates a relationship with Jesus, almost always seen as an infant in arms.
Jesus is the only intercessor. He told us to pray to "Our Father", not some sinful woman. (John 3:16- ALL have sinned. That leaves no exceptions for some Roman wannabe goddess!)
“Far from undermining the role of Mary, Jesus reveals the true greatness of her divine maternity. After all, she was not merely his natural mother through generation, but she became the Mother of God precisely by embracing the Father’s will (Lk 1:38, 43). Her relationship to Jesus—physical and spiritual—is thus magnified by Jesus’ statement.”
Scott Hahn.
So he did not rebuke her but since she knew she was his first disciple, the knew she was his mother but also the mother of us all. She is woman, the new Eve. One of only three created human beings who were born without original sin. The general Protestant version of Mary is amazingly anti-woman and sad. Even Luther venerated Mary so I’m guessing because I don’t really want to do the research that it was Calvin who was so anti-mary. This was the second iconoclasm.
