Otherwise, Christians fall into the same trap as Moslem's where the entirety of their law (sharia) is based on suppositions about what the Prophet and his Disciples might have said, might have done, or could have thought about something. Obviously, you don't understand the Bible or how it is applied in a believers life.
Not being critical, but based on what you posted, is completely wrong.
Apparantly you don't understand a thing about how Sharia law was developed.
For the first 300 years Moslems devised the Sharia by asking "What would Mohammad do"?
