Acts17apologetics find a balanced view; absolute Biblical corruption?

In answer to the video "Why the Quran Was Revealed in Arabic (David Wood)"

When the Quran states scriptures of the past were corrupted and tampered with, it never asserts corruption in an absolute sense. This is precisely why the Quran refers to itself as the Muhaymin (Guardian/Arbitrer), when talking about what is contemporary to it in terms of revealed truths, whether available in oral or writen tradition, such as the Torah and Injil. It points out major mistakes in them, filters the Truth from falsehood

21:24"this is the reminder of those with me and the reminder of those before me".

The Quran confirming the past scriptures, as well as any tradition, oral or written, in which divine truths still remain 2:41, means that the principles taught by Muhammad come from a common source and can be found throughout these textual and oral traditons. It also means the coming of Muhammad and the Quran prove the prophecies of the Torah and Gospel as true 6:20,7:157,61:6. It is in this same sense that Jesus confirmed and fulfilled the Torah and the Prophets. He confirmed the truth in them, exposing the falsehood, oral or textual, and he fulfilled the prophecies related to himself

Matt5:17-20,19:16-19,Quran5:46"And We sent after them in their footsteps Isa, son of Marium, verifying what was before him of the Taurat and We gave him the Injeel in which was guidance and light, and verifying what was before it of Taurat and a guidance and an admonition for those who guard (against evil)".

The Bani Israil who rejected Jesus were in reality rejecting their Torah. Now that the Quran came, if the people of the book do not stand firm by it, then they will be violating even their own scriptures which it confirms and fulfills. In 46:10 the Quran refers to a witness from among the Israelites that believed in the like of his scriptures, meaning the Quran.

According to tradition, the verse is speaking of the learned rabbi Abdullah ibn Salam's conversion to Islam. Given his religious knowledge, he knew the Quran abrogates and supersedes, exposes and denies, confirms in places while contradicting in many other places his own scripture, the Torah. But yet it literally says, this rabbi believed in the like of his scriptures. That "likeness" between the Torah and the Quran therefore can only be the statements that fully agree with one another. This is exactly what is meant by Quran confirming the past revelations. It confirms the truth in them in several ways, including exposing what is from God and what is man-made, hence its function as the Muhaymin/guardian,arbitrer as well as fulfilling its prophecies, which the Quran repeatedly echoes and which of course the learned rabbi knew applied to Muhammad

2:146"those to whom We have given the scripture recognize him as they recognize their own sons"..

That is also why the minority comentators that rejected the application of the verse to ibn Salam, rather see in it a reference to Moses himself. He was the Israelite witness that testified to one like himself/mithlihi, as clearly stated in the prophecy of

Deut18:18"I will set up a prophet for them, from among their brothers like you and I will put my words into his mouth and he will speak to them all that I command him".

But as attested in history, not all of them remained obdurate

3:199"And most surely of the followers of the Book there are those who believe in Allah and (in) that which has been revealed to you and (in) that which has been revealed to them, being lowly before Allah; they do not take a small price for the communications of Allah; these it is that have their reward with their Lord; surely Allah is quick in reckoning".

These are the righteous among the followers of previous scriptures and who remained truthful to their Books. This sincerity inevitably led them to believe in the Quran

4:162,5:83"But the firm in knowledge among them..believe in what has been revealed to you and what has been revealed before you...and when they hear what has been revealed to the apostle, you will see their eye overflowing with tears on account of the truth that they recognize. They say; our Lord, we believe so write us down with the witnesses".

A subtle aspect worth noting in 2:121 is that since the righteous among them are mentioned, the expression used is "We have given them the Book" not "They were given the Book" conveying the idea that it is God who gave it to them and guided them on account of their righteousness, contrary to those who were given the book without identification of the giver or instructor. This pattern is present throughout the Quran and is actually one of the many examples of its linguistic precision.

This is why the people of the book are never told to reject their scriptures in 5:68,69 but rather to stand by not only the Torah and the Gospel, but the Quran, to which the previous scriptures naturally lead to. This has been pointed to in the words

"and that which is revealed to you from your Lord".

Because it is the "Muhaymin" of their revelations, the guardian of the truth which God himself has pledged to preserve unlike any holy book, the reminder of the pure way of Ibrahim. As to those who would claim, and still do, that they only believe that which has been revealed to them then the Quran answers them that even Prophets that came from among their own people, preaching adherence to their own books were killed by these men, as Jesus put it Mk12:1-12,Matt23:31-37. This charge was levelled against them in the earliest Meccan revelations such as 37:37 before the interraction with them in Medina.
