You can keep spinning it anyway you want. Bottom line is Roman Catholicism has elevated Mary to something not accorded to her in Scripture.
I agree that the Church has accorded to Mary things that have no direct basis in Scripture. The Church has never denied that; it believes that these things are divinely revealed through Tradition, handed down orally from Apostolic times. It is not my intention to spin that one way or another. It is what it is.
Bottom line in this discussion is that your statement that “Roman Catholicism has very subtly raised Mary to the status of Jesus and the Holy Spirit” is wrong. The Church has never asserted or implied that Mary has the same status as Jesus and the Holy Spirit. The Church has always stated that any role Mary has is handed to her from God, and that without God, her role does not exist.
And there in is the problem.
The problem with "Tradition" is that it contradicts what is revealed in Scripture. We've been told that won't happen, yet we see it has in these discussions.
The other problem is the time interval with some of these dogmas involving Mary. There's a considerable gap between when the NT period closed and when the dogmas started showing up.
I know Roman Catholicism has a ton invested in Mary.
There's no way the RCC could ever admit to being in error over this as it would destroy the RCC.
So many Roman Catholics have sadly hung their hat on what Mary can do for them they'd be lost without it.
