The act of interpreting the Bible differently based upon current social events. Although the words are not altered, the meaning behind the words are said to mean something different. It's also important to note, there is no common consensus in the interpretation. It's primary purpose is to argue and defense a losing position.
Atheist: "The Bible speaks of killing homosexuals. Read Leviticus 20:13."
Theist: "The meaning behind Leviticus 20:13 doesn't mean to kill homosexuals. It means that it's a sin punishable by death, but since Jesus paid for our sins and killing homosexuals is morally wrong, all they should do is repent."
Atheist: "Come on Theist, that's Biblical Evolution in which you're trying to change the meaning of the Bible. I call bullshit."
