But there is a revealed truth which is widely regarded as the inside track and has been for milleniums...and that is the Bible.
The Bible is "God-breathed" as Paul himself puts it; that is...men inspired by God's Spirit Himself set down the truth in words to communicate with us.
Now, it is up to an individual to believe that these words are authoritative; if he/she does not there are consequences. Mormons, Muslims (not equal politically but I must use them together in this example) add stuff to the Bible to dilute it's truths. Joseph Smith and Mohammed claimed to be unique prophets of god. Well, they were not...and the reason you can tell they are not is that what they said CONFLICTS with the Bible.
True, interpreting the Bible is a growing exercise. But if someone is speaking things contrary to clear Bible teaching you must reject it. In this case (Mormonism) what they believe about Christ directly conflicts what the Bible teaches and lowers Christ's status. That is no good because we must believe in Christ's unique, divine nature in order to enter Heaven. This is important stuff.
