Christian atheism is a theological position in which the belief in the God of Christianity is rejected or absent but the moral teachings of Jesus are followed.
~Wiki
Not really an oxymoron. Much like atheists can be subscribers to any number of philosophical schools a Christian atheist believes that Jesus' teachings are part of a philosophical school. Jesus is not God, but his teachings and life are inspiring and are a good guideline to be followed.
You can find atheists who do the same thing for Nietzsche and hold his philosophy as the best philosophy. There is no supernatural element involved with either. It is a philosophical element.
