How deep are you willing to go?
-St. Bernard
I am willing to go as deep as Christians belonging to churches founded by Christ's apostles (ie, Catholics and Eastern Orthodox) have traditionally done. I have yet to see any evidence that any one has become a worse person or a bigger sinner on account of their devotion to Mary. On the other hand, I am aware of much saintly conduct inspired by devotion to Mary.
The problem is that you take these quotes out of context. You see "Mary" and think of something like your mom; we see "Mary" and think of the Church, the new Eve, the Ark of the Covenant, etc. We have a rich, 2000+ year old tradition that is a tapestry of truth and you have a crusty interpretation from a dead theologian who rebelled against the truth. So sorry for you poverty.
You are baiting!
