I had a very interesting conversation with a very good Baptist in our Parish one time. Brian told me he had been a Catolic when he was young and had later become a Baptist. When I asked him why he told me that it was because the Church was theologically wrong. I asked him to explain and several of the things he said concerned Our Lady incuding the 'fact' that we 'adored' her. I pointed out that The Church didn't teach these things.
But, you know people believe what they want. However I wonder if Brian ever really was taught properly in the first place.
