Oh, I see before you start naming fallacies you use one yourself. I don't recall reading anything that says this is placed before the primacy of the scripture.
You get that? I get that the op is saying that it's not just 'charismatics' who have experienced laughter. But you're kind of building your own argument then tearing it down. Kind of circular reasoning there?
No, we must test the spirits to see if they're from God, unless you can direct me to see where it says to test manifestations? And while you're doing that testing, let the Joy of the Lord be your strength, just don't laugh while having that joy because...well
Argumentum ad ignorantiam? Again God tells us how to test the spirits. And do you really have that little faith in the staying power of God?
Now you use an argumentum ad populum to counter an appeal to authority? And you are right, one can be Christian and still be opposed to a lot of what God is doing. Like CS Lewis said, they can have bad doctrine that makes them bad Christians, but it's not his job to say who is or isn't Christian.
