I do not believe God allowed the wrong canon for 1500 years, until someone else came along like Calvin to set us straight. Nor do I believe Joseph Smith either with his book of mormon.
More importantly, if you are looking for the truth, God will give it to you. (Romans 1). The problem is not that we don’t have the truth. The problem is we want the easy, self serving, make you feel better version, which of course, is a lie
what do you consider to be the correct canon of Scripture?
The principle here is that "two wrongs do not make a right."
