The Bible has been corrupted and cannot be trusted as a true revelation from God.

The argument begins by acknowledging that both the Bible and the Quran have undergone textual transmission, which is common among ancient texts. However, the Christian response emphasizes that the Bible has a significantly greater manuscript tradition and external corroboration compared to the Quran. Furthermore, if Muslims assert that textual variants disqualify a text's authenticity, they must also apply this standard to the Quran, which has hundreds, if not thousands, of variant readings. This inconsistency highlights a double standard in the Muslim critique of the Bible. Ultimately, if the criteria for textual purity are applied uniformly, the Quran would also be deemed corrupted, leading to the conclusion that Muslims must reject it as well.
