Per this classic article by The Onion, services at this church were cancelled because God doesn’t exist.
Parishioners of Pastor Theo Leobald’s First Congregational Church of Holy Christ In Heaven will not meet next Sunday morning for a coffee social and morning Bible study as they do every week, gathering in fellowship and offering thanks and praise to God on high. The reason for the cancellation? Simply the fact that, according to Leobald, God does not now, has never, and will never exist. [The Pastor was quoted as saying] “So who are you gonna believe: Carl Sagan, and the pantheon of the world’s greatest scientific and intellectual minds, or some guy who measured wealth by how many goats he had?”
