WHAT IS A HYPOCRITE?
Why is the term "hypocrite" considered such a vile insult? Jesus condemned the Pharisees in Matthew 23 as hypocrites.
n : a person who professes beliefs and opinions that they do not hold
Here is the origin of the term.
c.1200, ipocrisie, from O.Fr. ypocrisie, from L.L. hypocrisis, from Gk. hypokrisis "acting on the stage, pretense," from hypokrinesthai "play a part, pretend," also "answer," from hypo- "under" (see sub-) + middle voice of krinein "to sift, decide" (see crisis).
