Ha, did you just fall out of a time warp? Santa Claus has zilch to do with religion, just like Halloween trick or treating has zilch to do with All Saints Day. These have both been secularized -- stolen if you will -- just like the Christian church stole the winter solstice celebrations from the pagans before them.
It's an old advertizers maxim -- steal what works.
What rubbish. Saint Nicholas of Myra (Santa Claus) has everything to do with faith in Jesus Christ.
