I don't believe the Quran says the Scriptures were corrupted, but attempts were made to corrupt the meaning of Scripture as it was in the time of Jeremiah so it is now. IMO, the Quran is an attempt to corrupt the meaning of the Scripture that came before. The Book of Mormon attempted to do the same and many other books attempt the same. There was no divine mandate given to the put the Quran to writing so, how do Muslims know it wasn't speaking of putting the recitation to writing as being the corruption attempted against the Bible or scripture that came before?

As I have mentioned, we Christians don't base our salvation on the OT Scriptures, or the torah which is a common source for Jews and both Christians and Muslims. Besides, Christians don't accept the Quran as the word of God; so, it doesn't matter what it says regarding the Bible. Moreover, logic alone tells you that the Jews wouldn't tell you in Jeremiah 8 they are corrupting Scripture by their lying pens, but they would make it appear perfect and uncorrupted. So it is stupid to say this. By cutting down Scripture, I believe this is the only way Muslims can support Islam and the Quran. What do your think?

As for Jesus, I have mentioned many times that Jesus is all that God is, but He is not all there is to God. This is a mystery that is past finding out just as God is to human understanding. The god of Islam could be understood by finite man but not the God of Christianity!

Blessings to all!
