I would have to say Judaism . The reason being they believe most things that Christians believe as well as are another persecuted group. "Blessed are those who are persecuted for righteousness sake for they shall see God" (can't remember exact scripture but its in the Beattitudes). There are subsections within Judaism that believe that Jesus is Lord. I don't think that I can stray away from what I consider to be the truth to follow/practice another religion without some type of belief in the eternal existance of Jesus.

However, I would research Satanism. Reason being, to truly defend your own practices and beliefs you would have to understand the opposite.
