You have not taken into consideration the full implications of our membership in the mystical Body of Christ interns of our cooperation in the plan of Salvation. All of our cooperation: Paul’s and Peter’s and *yours*, as well as Mary’s.
Even Mary’s cooperation, unique though it is, is just part of a much larger picture. I don’t think you or I have yet grasped how big this is.
Any reliance upon Mary negates Jesus's exclusive claim He makes in John 14:6.
"I am the way, the truth, the life; no one comes to the Father but through Me."
The Greek emphasizes that there is no other way to Heaven but through Christ. It does not give an allowance for any other way.
You may recognize the following promise from Our Lady's 15 Promises for Praying the Rosary
5. The soul which recommends itself to me by the recitation of the Rosary shall not perish.
This is totally incompatible with Jesus' statement in John 14:6...and the rest of the NT for that matter.
There is no way the catholic can spin this to be compatible with John 14:6.
