Many small businesses would rarely have more than a couple of customers inside of them at any one time, but no business would be allowed to be run out of a private home zoned residential.
There is a point (a debatable point) at which a “bible study” would become a church... and churches are not allowed to be built in areas zoned residential.
The point is that this is an attack on religious freedom that is protected by law. A “church” is when two or more people are gathered in worship.
It shows how archaic and provincial the zoning codes and zoning boards have become. Technology has transformed what constitutes the work place. Also, the question of 7 adults gathering to worship God doesn't affect public safety.
Any govt official associated with telling these people they can't peacefully gather in someone's home should be ashamed of themselves.
