In 2013, two British comedians "wanted to do something that was like church but totally secular." Sanderson Jones and Pippa Evans were on their way to a gig when they discussed the idea. On January 6, 2013, the first-ever meeting of the Sunday Assembly took place in The Nave, a pub in the boroughs of London. The Sunday Assembly has since spread all over, mainly in the UK and in the US.
There were about 70 independent congregations. Ever since the pandemic hit, more than half have gone dormant or completely closed.
