So how do you decide when God is speaking and when men are speaking?
I don't. I don't have to.

What “nonChristian” belief came out of the Reformation?
Where to start... I would suggest that you select a particular church and look at their beliefs as advertised, and then move on to the next one. They should be rather obvious.
Abdicating personal responsibility could cost you greatly.
John 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
Acts 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.

I already did that. The Catholic Church was the worst. Why do you think I’m not affiliated with any organized religious organization?
