Why are there so many denominations in Christianity?  Doctrine.  While many make up doctrines wholecloth, others will do it by cherry-picking verses in scripture.  In this presentation, I show you an example of cherry picking data by Ancel Keys and then I apply this to show how the "data" in Paul's letters can be cherry-picked to support a "faith only" salvation, and then a "works only" salvation.  How to reconcile this?  Well, once you realize that faith and works cannot exist without one another, then the apparent contradiction disappears.
