I thought that “Calvinism” had essentially disappeared into (perhaps buried by) Methodism & Presbyterianism, at best. Or into Congregationalists & its semi-religious/secularist descendants.
Interesting, the strange ideas people get.
Perhaps strange because I don’t see ‘the first church of Calvinism’ in any town, one does find Methodist and other churches that grew out of Calvinism. But never hear much mention of Calvin, or Swingel, others from the 15th & 16th Century, except for Henry VIII.
