"In my acceptance", there is no difference whatsoever between belief in Santa Claus and (some people's) belief in God. Go ahead, start a topic. I dare ya.
There was an excellent article on that very subject that was posted on our church bulletin board for a long time. I sure wish I had run a xerox of it before it was taken down (I asked, but nobody in the office could find it).
Most people's ideas of God were formed when they were children and, as they matured, they failed to go back and revised those ideas. So most people have immature and childish ideas and beliefs about God. "God as Santa Claus" or "God as Cop" or "God as Big Brother" (as in "1984") or "God as Dutch Uncle".
Since "sound bites" are being thrown around here, I'll offer one that's most commonly associated with our church:
"To question is the answer."
We need to constantly question our beliefs and our understandings. Because we are human, most of our beliefs and our understanding of things, including of our beliefs, are mistaken. Only by questioning what we think we know and understand can we detect when we're mistaken. By refusing or neglecting to question anything, we run the certain risk of holding blindly to childish beliefs which are certainly wrong.
