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.
As I said, you don’t even deal with the salvific significance of the Body of Christ. You don’t even engage.
Where do you see anyone claiming that anyone can "come to the Father" through Mary, apart from Jesus?
The Catholic formula is "through Mary to Jesus," NOT "through Mary to the Father, and just leave Jesus out of it". What you're doing amounts to a strawman argument.
