What do you mean by Church?
A “church” is different from a “faction” (denomination).
One should only ask one question before “deciding for yourselves” which is:
‘Did Lord Jesus Christ author your denomination?’
The next related question is “Did Lord Jesus Christ author the denomination which existed before yours?”
If your answer is an affirmative “yes ” to both questions above, then the last question to consider is, “In the doctrines where your denomination differs from previous ones, isn’t that “confusion” which God clearly states in Scripture that He’s ‘not’ the author of?”
So, “decide for yourselves which is right.”
