Do atheists named Christopher or Christine have trouble believing in themselves?
Names are labels. A guy named Björn or Ursus (bear) is not nessesarily strong as one. A girl named Chastity is no more likely to be chaste than one named Salome. My name is Jakob and I have never met an angel, much less wrestled one. Several religions (including some Christian branches) ask youngsters to name themselves when they come of age or get baptized into the church. Not a bad idea. Christian and Christine are just names. At most we can take them as indications of what the parents wanted their baby to become, but most often not even that, the names of wealthy uncles are very common, and who knows what reasons his parents had.
