Mary was blessed but not venerated or to be prayed to as an intercessor
So, when did the pope change that to the bastard version of today?
Quite a while back, the current Pope may be the last one, the policy of praying to Church officers (Bishops) as well as other “Saints” is a position they claimed they had authority to do over a thousand years ago
I have seen more weird positions from Him than any pope in history and there have been some real winners if you know what I mean. Ratzinger wanted to normalize things but the more radical/weird elements in the church stopped him and now look at what they have.
