This is why a brother in Christ of mine, a conservative Baptist type once told me of his attitudes towards Protestants from Anglicans to Presbyterians "...the past churches would split out of denominations because they were hearing things that were against the word of God. Sometimes they would keep ideas and just reform them. The hooks left in the jaw of the protestant churches in their reform are the very same hooks that are drawing them back to the RCC[and Orthodox church]... They [mainline Protestants] cannot understand us because they were never of us. Anabaptist were on the outside of the RCC while the RCC is their mother. It is no wonder they understand her."
That is quite a claim, especially in light of the article that began this thread. Did you read it? Think it's at all possible we've taken the position we have, because we understand you only too well?
