The sole source of genuine Christian faith is found in the 66 Books of the Holy Bible. Any other location immediately tells us we don’t have the right faith yet. We must not put our time, effort, and money (i.e. our lives) in something that does not come from the Bible.
In other words, if we can’t read about our Church in the Bible, then our Church isn’t the church Jesus built (Mt. 16:18-19).
