Because of the controversy around the Unitarian Universalist Ministers Association's public censure of Todd Eklof, there's been talk of heresy trials. Of course, there's no trial yet, just the censure and waves of accusation, though some formal action could happen. (I wonder what the euphemism will be?)
There was a trial of a Universalist minister, Herman Bisbee, that's widely regarded as a heresy trial — and a mistake. Naturally, it's come up in the Facebook conversations (with Michael Servetus, whom I'll leave for someone else to write about) so good to give some context to those unfamiliar with the situation. I'm going to pull together what I've written about it plus any original documents I can scare up.
But Charles Howe's article at the Dictionary of Unitarian & Universalist Biography is detailed, and rather than re-write one, I'll point to his.
