Not to sound offensive, but there isn't truth to be found in any church.
I don't know if I'd say there is no truth in the churches. Life is seldom black and white so they may have a little bit of truth mixed in with all the nonsense. Who has the truth?
John 17:17,
Sanctify them through thy truth: thy word is truth.
That statement needs no explanation. Very simple sentence structure. No interpretation required. It says what it means and means what it says as does the entire Bible once the reader is freed from the typical church teachings. The reader is free to believe it or not. Either way no person can judge another individual. Nobody has what it takes to judge correctly except God and He judges quite differently than man.
1Sam 16:7b,
...for [the LORD seeth] not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart.
And should a Christian forget that and judge another, it is worth remembering:
Rom 2:1,
Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things.
