So are you suggesting that I write to the Vatican to get clarification on that issue?
But if I want to do that then I want “Pope Francis” himself to look into that issue not anyone from his assistants! which maybe impossible to do…

Sam, we are all assistants of Pope Francis here. As you mentioned in your PM that you do not consider this issue closed and I hope I can be of service. I think I understand where you are coming from and it will not be easy to break a paradigm of a lifetime. Your differences of opinion and head-banging of walls that resulted is likely the same intractable difference I mentioned in my post in a separate thread. There is a fundamental difference in Muslim and Christian views of revelation (please see my posts in that separate thread
here, which I will not repeat as they are several and long - but please read them if anyone intend to follow my reply here). As one poster put it, you would need to unlearn the Muslim concepts if you wish to learn the Christian one.
There is a huge difference in how Paul wrote his letter which eventually found its way into the Bible and how Muslims understood Mohammad’s role in relation to the Quran. Mohamamd basically took dictation from the angel Gabriel and his role was clearly just a broadband cable for the literal word of God. To study the Quran, it is not necessary to understand Mohammad’s frame of mind when he received the revelation, the background of his people or the historical context of the audience the scripture was directed to. It is the literal word of God, unblemished by any human flaws and protected from all errors, not merely as a revelation, but also errors of translation (only the Arabic Quran is the authentic Quran and to study the Quran, you not only need to know Arabic but also its philology, etc).
In Islam, there are only four Messengers to whom the literal revelation of God was revealed, including Moses (Torah), David (Psalms) and Jesus (the Gospel, note the singular) with Mohammad as the last one. The word Messenger is instructive as their role was really to pass on the message and preach to everyone who hears it to be obedient to it. In addition to the four Messengers, there are prophets (which include those we call patriarchs like Adam, etc) whose role is to preach obedience to God’s revelation. In their mission to transmit and/or preach God’s literal revelation, Muslims believe that the messengers and prophets are
preserved from error.
So, there are three fundamental differences (from Christianity) here in what Muslims are taught:
1 Scriptures as the literal word of God and have no context
2 Scriptures are transmitted by Messengers as conduit of God’s revelation
3 Scriptures and those writing them are free from all types of errors.
Scriptures as the literal word of God
Unlike Muslims, Orthodox Jews and fundamentalist Christians, Catholics (and most other mainstream Christians) do not believe scriptures to be the literal word of God. God did not personally write the scriptures but inspired men to do so (so far, scriptures are only written by men but revelation can be to either gender, eg., at Fatima). This inspiration was not placed into these men as fully formed words, as has happened to Mohammad, but as truths - as in ideas and concepts.
For instance, God taught Paul the truth about love (we don’t know how he was taught - could have been directly as in a dream, taught by another man inspired by God, or taught through an experience of love Paul came across - and we do not think it is important to know how God taught him: suffice to say that he understood) and based on this understanding, Paul wrote 1 Cor 13. What is important for us is not the words of 1 Cor 13, important as they are, but the message of love that Paul intended us to understand. Frankly, if we had misunderstood the words because of our poor grasp of the language but has understood the message of love, I don’t think Paul (and God for that matter) would have cared. We may exalt 1 Cor 13 not because its is beautifully crafted, even though it clearly is, but because of the truth of the message they contain. The words are only receptacle for the truths, and just as we can contain the same coffee in different cups, we can use different words to convey the same truth.
That is why we do not accept that the only authentic Bible is the orginal Hebrew and Greek. The words are constantly translated and re-translated for the intended audience. Even within the same language, translations need to be updated due to changes in word use and word meaning (eg., English useage have changed substantially since 1611, which is why most of use struggle to understand the words in KJV). What is important is the message to be conveyed and not the words. Words used are derived from the meaning to be conveyed, not the meaning from the words used. For us the meaning came first, not the words. Faith came before scriptures. Christianity existed before the Bible.
This differs from the Quran, which cannot be changed or translated from the original Arabic (apparently, God could be an Englishman but he spoke seventh century Arabic). Translated Qurans do not have the stamp of authenticity as God’s word. Not a vowel or punctuation can be changed as it is what God personally spoke. The first caliph confirmed the authentic Quran and all other versions were destroyed - all Qurans today are identical. As far as I know, only one pre-Othmanic scroll was uncovered in Yemen, and the difference were extremely minor (eg., arrangement of the passages).
