Through out debates among Christians and Muslims, Muslims are regularly asked: why they quote from the Bible as evidence if they believe the Bible has been corrupted? By using this question as an excuse, most of the time Christians reject the arguments put forward by Muslims. When I was debating online with some Christians called ‘The Confessors’, I was posed the same excuse/question. They even demanded that I prove the authenticity of the verses I quoted from the Bible just because I believed the book to be corrupted. This article is in answer to Christians who ask such questions to Muslims in debates regarding the Bible.
Asking for proof
Basically, The Confessors have been asking me to prove their own Bible to themselves, the same Bible which they believe to be the word of God. I am sure that such a demand entitles me to question their faith in the Bible. Do The Confessors believe the Bible to be 100% authentic? If yes, then why do I need to prove that to them?
Although it is generally logical for anyone to ask for evidence of authenticity, it is very illogical for one to ask for evidence of authenticity regarding something that he/she already believes to be authentic. For example: if person A knows that two plus two equals to four, then it would be really foolish of person A to demand proof for this from person B. Evenly, it is absurd for a Christian to insist evidence of authenticity concerning his/her Bible.
Produce your proof if ye are truthful
The reason why Muslims use the Bible to disprove Christianity (even though they believe the Bible to be corrupted) can be simply answered with a verse from the Holy Qur’an:
“And they say: “None shall enter Paradise unless he be a Jew or a Christian.” Those are their (vain) desires. Say: “Produce your proof if ye are truthful.””
The Muslim is told in this verse that Christians and Jews (will always) declare that no one can enter paradise without being a Jew or a Christian (or that Islam is wrong, etc.), to such a claim the Muslim is to demand proof. And the Christian has made the effort to meet this insistence of the Qur’an. Ultimately, the Christian will say that the Bible is his/her proof. According to the Christian, Islam is a false religion because they get this from the Bible, that Muslims are sinners and that they will never enter paradise. So because the Christian uses the Bible as evidence and proof for such claims, the Muslim is forced to examine the Bible (regardless of whether he/she believes it to be true or not).
Everyone agrees that the topic ‘Is the Bible corrupted?’ is a whole debate by itself and an interesting subject to discuss. But when a Muslim uses the Bible to prove something to the Christian (even to disprove Christianity itself), it is because the Christian believes the Bible to be 100% true, the Muslim will use this against him/her. And regardless of whatever a Muslim believes, any valid evidence from the Bible should be enough to convince a Christian right? Understanding that it is logical to ask for proof of authenticity regarding the Bible, but if this question is coming from a Christian then it shows that he/she is having doubts about the Bible.
