An orginal text of what?
What Muhammad wrote down with his own hands?
I would love to see this!
The KJV can be compared to the Quran because Muslims and Christians both do the same thing. They take a human language and make it into an idol.
idol
That on which the affections are strongly (often excessively) set; an object of passionate devotion; a person or thing greatly loved or adored.
This idol within their minds becomes the spirit they use to understand what they are reading.
They don't use the Spirit of God to understand what they are reading, they use this man made spirit.
If this man made spirit doesn't have all the answers then they create commentaries written by men to answer them.
Where do you fit?
