The perfect Bible issue (I did not say KJV) is not a head issue, it's a heart issue.
It's naturalistic philosophy VS faith in the power of God.
Human non-scriptural KJV-only reasoning would be naturalistic philosophy since it is not biblical faith in what God actually stated. Perhaps you advocate emotional, blind faith instead of sound biblical faith.
Believing assertions that are not true would not be displaying faith in what God said, but instead it would be deceiving one's self.
