Thanks, that's the point I was making in response to someone's claim that Protestant churches are in communion with each other even though there are doctrinal differences.
did you read the rest of the post? what unites us is more important than what separates us as protestants
Your problem, though is that one example where that does not happen, does not mean it's an across the board situation for all Protestant churches.
There are other non-Catholic churches where people of different denominations share the pulpit and communion.
You have not proved your point.
