Same to you, FollowChrist34. Yes, it was a LCMS parish that we visited, by the way.
I have been trying to explain to my wife that she should consider Mary and the saints as our heavenly prayer partners and that Mary deserves honor and respect for saying ‘Yes’ to God when she didn’t have to do that and for being there for Jesus not only at his birth but at the cross also, along with raising and loving him every step along the way.
She still thinks that Catholics go beyond honoring her and delve into worshipping her in the adoration sense, which we are against, but that’s another topic for a different thread because I know Catholics deny doing that in the way that some Protestants believe Catholics do.
(actually I think the Mary dilemma is spot on for this thread) The only thing I would add on that: I know this is an incredible stumbling block for Protestants - my Evangelical friend even snarled once at me about worship of Mary in an unguarded moment (or maybe it was the margueritas - we have Mexican dinner get togethers every couple of months).

I snapped right back though - no worries. That was the end of it - we switched the topic.
I am not a really Orthodox, traditional dyed in the wool cradle Catholic, so to be honest the Mary thing mystifies me a little bit. And I will actually tell you that I see Catholics who seem to take it to adoration (in every denomination people get their faith wrong - even if they sometimes know they are doing it wrong). But it doesn’t freak me out or anything, probably because I have been around rosaries, etc. since I was a kid. I have never had anything but deep love and affection for Mary myself - so I don’t have a bone in my body that would go against her. She is the Mother of God. So I am kind of in the middle on this one I guess.
You need to talk to a really good Catholic apologist on the Mary thing maybe with your wife. Sounds like you already know the explanation though. Again, I go through periods of praying to Mary, periods of praying to Jesus. And I always pray to Mary as the Mother of God.
The saints I have never had an issue with either - though to me they are inspiration - the intercession thing I believe but don’t really emphasize at all in my inner prayer life.
Lastly, the other great thing about the Catholic Church is the access to the history of the Church and its wisdom and knowledge - the fathers of the Church, etc. Augustine, Aquinas, Desert Fathers, the writings of the saints. There is so much to the Church - even some of the Protestants, Luther, Kierkegaard. I think all Christians should take advantage of this.
