It is best not to begin with Adam and Eve. Original Sin is 
baffling, even for the most sophisticated minds. Besides,
children are frightened of naked people and apples. Instead,
start with the talking snake. Children like to hear what animals 
have to say. Let him hiss for a while and tell his own tale.
They’ll figure him out in the end. Describe sin simply as those
acts which cause suffering and leave it at that. Steer clear of
musty confessionals. Children associate them with outhouses. 
Leave Hell out of the discussion. They’ll be able to describe it 
on their own soon enough. If they feel the need to apologize 
for some transgression, tell them that one of the offices of the
moon is to forgive. As for the priest, let him slumber a while
more.
