The Santa Claus as celebrated is so far removed from the christian saint St Nicholas, and from anything in the christian "universe" for that matter (heck, there's even a flying reindeer involved and little elf people) that it might as well be a totally different person.
Not to mention that he has nothing to do with the Christmas's eve (he has been traditionally celebrated for millennia on the 6th of December), or with extreme shopping.
(sadly, the Church would be destroyed in the 9/11 attacks, and IIRC, the relics were never recovered.)
The bad news: Santa Claus is definitely dead.St Nicholas, pray for us!
