The only reasonable thing to do in this situation is trust to an authority.
This is another of those self-contradictory claims of the RCC cult followers. Apparently, you admit you are not competent to interpret the Scriptures. How then are we to believe YOU have the authority to decide that I am "incompetent"? You have viewed all of the interpretations of Scripture I have made and you, sitting in that seat of judgment because you are the AUTHORITY, have found them wanting? You just admitted you are not competent to make such calls. What competency, pray tell, sprung up for you to make this pronouncement upon me?
"With all due respect I doubt that you know any other language beside English. Otherwise you would be aware that even the best translator is unable to make EXACT translation."
Well, here are two more beauties. I have trained in Koine' Greek at a recognized university and have a degree in theology. Koine' Greek is the language used by the NT writers. But, that is not your biggest error. Your biggest error is that you claim no "EXACT" translation is possible, but yet you trust your "scientists and theologians" to provide you such work. Is their work "EXACT" or is it defective? How do you know? If your trust in their AUTHORITY is based on their interpretations, which came first, your blind trust or their AUTHORITY?
"INTERPRETATION ALWAYS MUST COME FROM THE ORIGINAL SOURCE."
If by this you mean (notice I have to interpret your words) that interpretations must come only from original languages, then you have no idea what you are talking about. If one of your "theologians" says, "Jesus means you should jump off a cliff here.", you must still take that phrase he interpreted into English and interpret it within your mind to mean something. You are now using your own personal interpretation technique to decide what the theologian's words mean. Otherwise, how do you know what he is getting at? The original languages are useful, very useful. But, it is the meaning of those phrases within our language that becomes what we understand. You do it all the time and so does everyone else.
But, curiously, what interpretations do you think I have made incorrectly?
