I do understand.
You said:
“I am a Christian, a member of the Body of Christ, it is simple.”
Then you are a member of a religion - the Christian religion, but only a Protestant member rather than a member who believes in the full faith.
“I am sorry you do not understand that.”
I do understand. Like many Protestants you do not seem to understand what you’re talking about.
I am not a Protestant, I am a Christian.
Your feeling of superiority is really quite interesting, and the new Pope is a such a humble man....maybe that might help you a bit to follow his lead.
