Episode notes
Servetus The Polymath Who Alienated Peers
- Michael Servetus was a polymath who studied medicine, astrology, and theology and became notorious for abrasive behavior that got him expelled from institutions.
- Jonathan Moorhead highlights Servetus's medical claim to the pulmonary circulation and his tendency to insult teachers, which shaped his later trials.
Calvin Was First Among Equals Not A Pope
- John Calvin was first among equals in Geneva's Company of Pastors, not an autocratic pope, and he lacked civic authority like voting or carrying a weapon.
- Moorhead notes Calvin couldn't vote or judge during Servetus's trial and only later obtained citizenship in 1559.
How Servetus Was Exposed By A Cousin's Letter
- Servetus published anti-Trinitarian works under pseudonyms and was later reported by William de Tré in Vienne to Geneva authorities.
- Moorhead recounts William de Tré contacting Calvin to obtain Servetus's letters, which Calvin initially resisted but eventually provided.
