Your post betrays a dearth of awareness of both Christianity and Islam.

There are many Christian denominations whose members are not "free to take what they will from their scripture and disregard the rest" but take a literal interpretation of the bible. 

Many evangelical and fundamentalist Christian denominations would fall into this description.

And there are many Muslims who are, indeed, "free to take what they will from their scripture and disregard the rest".
