You find truth in some of the strangest places.  I was reading an article online a couple of weeks ago, Unitarian minister Marilyn Sewell was interviewing atheist Christopher Hitchens.  Hitchens who passed away last week, talk about “all dressed up and no place to go”, was the author of “God is not Great: How Religion Poisons Everything”  
Rev. Sewell, a liberal pastor,  felt that the book’s criticisms were mostly directed at conservative Christianity and so she asked the author,  “Do you make a distinction between fundamentalist faith and liberal religion?” 
And Hitchens said and I quote, “I would say that if you don’t believe that Jesus of Nazareth was the Christ and Messiah, and that He rose again from the dead and by His sacrifice, our sins are forgiven, you’re really not in any meaningful sense a Christian.”
So, you would think if an atheist can figure that out it must be a fairly straight forward concept.  The question then has to be: How come there are churches that would deny the virgin birth, the deity of Christ, the bodily resurrection of Christ and his atonement and yet still call themselves “Christian” Churches?  
Maybe for some the challenge shouldn’t be keeping Christ in Christmas but keeping Christ in Christianity.  Have a great week and remember: To see what is really possible, you will have to attempt the impossible.
