But nearly as quickly as the Assembly spread, it split, with New York City emerging as organized atheism’s Avignon.

In October, three former members of Sunday Assembly NYC announced the formation of a breakaway group called Godless Revival.

“The Sunday Assembly,” wrote Godless Revival founder Lee Moore in a scathing blog post, “has a problem with atheism.”

Moore alleges that, among other things, Jones advised the NYC group to “boycott the word atheism” and “not to have speakers from the atheist community.” It also wanted the New York branch to host Assembly services in a churchlike setting, instead of the Manhattan dive bar where it was launched.
