A subset of Christians who read the Bible from Genesis to the nativity, and then skip to Revelations at the end, the point being to purposefully exclude the actual teachings of Jesus Christ. The Christmastian belief system is founded primarily on ancient pagan celebrations that were adopted by early Christians. Christmastians reject peace, love and forgiveness and embrace vengeance, violence and never-ending war.

George W. Bush is a Christmastian
