The thing that always separated the Church of Christ from other mainstream religions was the often expressed belief that no one would be found in heaven aside from those who were members of the Church of Christ. This belief puts these particular Christians in a position of being among the most intolerant of any believers in Christ.
I don't think Christ would have cared much for them, but don't try telling them that. Their veins bulge in their necks and their eyes become blood red when confronted with any sacrilege. They give Christians a bad name, and I have yet to have one of them give me a good explanation of why a musical instrument cannot be allowed in church.
