Here's something I was surprised to find on his Wikipedia entry (could not immediately locate original source):
In an interview in the late 1980s, Schulz stated that his philosophical views had changed over the years:
"I do not go to church anymore ... I guess you might say I've come around to secular humanism, an obligation I believe all humans have to others and the world we live in."
Charlie Brown Christmas Special re-runs had fooled me into believing Schulz's religious views were forever locked in 1965.
