I'm still puzzled about why Genevans objected to Calvin's program of having Communion services at different churches every Sunday since such a policy would have been permissive. If someone wanted to go for Communion every Sunday they could--by going to a different church every Sunday. If they didn't want to go for Communion every Sunday, they didn't have to. They could stick with the same church and go for Communion whenever it was offered there. Or, for that matter, they could go for Communion as frequently or infrequently as they pleased.
Even assuming that every Genevan was required to go to church every Sunday, given this policy, no one would have to go for Communion more (or less) often than he wanted to. So where was the the beef? Am I missing something? Why would anyone oppose merely making it feasible for individuals to go for Communion every Sunday if that was what they preferred?
