People disagree on what Christ and God meant... because not all people are listening to Christ, and Christ alone. But rather also to men, tradition, religion, doctrines, all of which pass down from previous lack of knowledge/understanding. Sometimes people also don't understand, and so do not have an accurate understanding of the truth... and so discussion can help them SEE and HEAR the truth... in light OF the Truth (Christ).
Christ does not give His sheep conflicting knowledge. Truth does not contradict itself. But not everyone listens to His voice who claims to be a christian. That is why every claim can and should be tested against the Light... who is Christ, Truth.
I mean... you know all of this already. AT least you should if you ever actually WERE listening to Him yourself. Right? Christ Himself warned that false teachers would rise up among them... to mislead many. Including trying to mislead even the elect among them. Those false teachings are still around, and many believe them as true because they are accepted, traditional, believed by many, etc. So there is that whole forewarning thing again... no one's fault but your own if you didn't actually believe Him... becasue you weren't actually listening to HIM.. when you were a believer, that is, and claiming to know Him.
