We must be tolerant but no one has the right to tamper with Quran. Let us call a spade a spade. Rashad Khalifa committed a theological crime by dropping the last two verses of Surah Tauba. Allah is surely the Ultimate Judge but He has given us sense. Our judgment must discard a man like Rashad instead of accepting his transgressions.
Read Rashad's appendix to his translation and you see him coming out as a very confused and irrational man.
His Code 19 is a big fraud. Like numerous people I have tried it. It fails more than 70 percent of the times.
The Quran says:
2:42 Do not confound the truth with falsehood, nor conceal the truth while you are well aware of it.
You are telling us to go against the Quran. Ask forgiveness of Allah.
