I hope this message from the pope in March will convince you that Jesus is the only mediator and intercessor. Stop making Mary something she is not! She can't hear your prayers!
On Wednesday, Francis said that Christ is the mediator par excellence, the “bridge that we cross to turn to the Father,” and the only redeemer: “Every prayer that we give to God is for Christ, with Christ and through Christ, and are realized through his intersession.”
He also said that while the devotion to Mary is expected, some things applied to her are mere foolishness.
Jesus is mediator of the covenant by justice but the apostles also mediate at his command
2 Corinthians 5:18
And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
Luke 22:30
That ye may eat and drink at my table in my kingdom, and sit on thrones judging thetwelve tribes of Israel.
And anyone in the communion of saints by the action and of the mediator thru the power of the Holy Spirit can pray and intercede rev 5:8
