Frankly, aside from SBs, I don't know enough about those other faiths to comment on them intelligently. From what I do know, I think I would feel general unity with any Bible-believing church. I do not think it is fair to define protestants as any "Christian" church that isn't Catholic. So, while SBs and JWs are both not Catholic, I have no association or agreement with them at all. However, in my own Southern Baptist church, I am sure there are plenty of people whom I respect who do not share my reformed views. That's OK, and I have no plans to leave my church. We are nevertheless in unity because of our reliance on the Bible, and many other beliefs.
oh, I'm not talking about the thigns that unite us Christians (all) --> I simply said that if we were to answer a "Protestant" in one post, that could be answering one grouping's beliefs, but another might say -- hey, we Protestants don't believe that.
