It seems to me, you are looking for some kind of validation that could be hung on one particular denomination or some church teaching or type of worship.
What is binding? Only the Truth of God as revealed in Scripture. All other views, if they cannot be confirmed by the Scriptures is to be rejected. Scripture teaches that salvation is through Jesus the Christ - ALONE. Not some manmade Jesus but the one described in the Scriptures. Since salvation comes through Him, this rules out any validity in other religions... such as: Native American traditions, Moslems, Hindus and so forth.
Scripture establishes the true system of faith. (It's origin, how it works, what is to be believed and what is the promise.) When men pass along the word of God by mouth, they can misspeak. When one teaches the Word of God they can err. Only the printed Word of God - Holy Scripture - is inspired by the Holy Spirit. So ALL things must be proved through them and they alone.
If the things above are not true, then we might as well go back to partying like it was 1999 because we have no objective standard to learn by or judge.
