In this day and age (as in every age) there will be those outside the church who seek to criticize and degrade the bible.  But (also as in every age) there are also those from inside the church (or who claim to be anyways) that can do the very same thing, all in the name of "authenticity."  

Here is a great response from Andrew Wilson to one of today's most well know biblical revisionists.  I pray it deepens your own trust in the Scriptures as well as equips you to answer those who you may encounter in your own life who try to redefine orthodoxy.
