Oh that’s simple. I do and I imagine most here do as well, go to the source when I have a question about Protestantism. I react here to what others post, usually with my own thoughts and words as I understand it. If I say something is a formal Church teaching, I am going to go to the authentic Church to make sure that what I am saying is true.
I have a great deal of love for the Protestants I personally know and have listened to many Protestant ministers preach on the Bible. I do not discount them just because they are Protestant and have heard wonderful sermons regarding Christianity and living as a Christian.
When something is said that I believe is against the Church, I do not just blow off the entire sermon as I know the minister is a honest believer in what he is saying, just not one of a Catholic understanding.
