Some Muslims say the Bible has been altered and should have read perikleton rather than parakleton, claming the Bible has been falsified to fit Jewish and Christian beliefs and only the Quran is true.
This requires many steps of faith on account of the Muslims. 1. Jesus, Mary and Moses were really Muslims and spoke of Muhammad. 2. The New Testament is falsified. 3. Ignore the Dead Sea Scrolls, and 4. When Jesus speaks of the Spirit of Truth he really means Muhammad, not the Holy Spirit as He says in verse 26.
As a Christian I am free to take God’s Word for what it says.
