1. The Old Testament clearly testifies that it was altered by humans. God (Allah) is quoted in Jeremiah 8:8 as saying, “How can you say, ‘We are wise, and the law is with us?” But behold, the false pen of the scribes has made it into a lie.”21
2. Dr. Abu Ameenah Bilal Philips has explained: About five years after the end of Jesus’ ministry, a young rabbi by the name of Saul of Tarsus, who
claimed to have seen Jesus in a vision, began to change Jesus’ way. Paul (his Roman name) had considerable respect for Roman philosophy and he spoke proudly of his own Roman citizenship. His conviction was that non-Jews who became Christians should not be burdened with the Torah22 in any respect. The author of Acts 13:39 quotes Paul as saying: And by him every one that believes is freed from everything which you could not be freed by the Law of Moses. It was primarily through the efforts of Paul that the Church began to take on its non-Jewish character. Paul wrote most of the New Testament letters (epistles), which the Church accepts as the official doctrine and inspired Scripture. These letters do not preserve the Gospel of Jesus or even represent it, instead, Paul transformed the teachings of Christ into a Hellenic (Greco-Roman) philosophy.23
3. The clearest evidence of biblical distortion is the revision of the Bible, to the extent that it can be said that every edition is different from the previous one.
