Whenever Calvinists try to defend John Calvin and his role in the execution of Servetus (October 1553), they usually take the same approach as SA apologists: "yeah, Jenny being gang SA'd was wrong, but she was a jerk in 5th grade and also, she wore a short skirt: kinnda asking for it."
Here is one response by Christopher Fisher (vs. Gavin Ortlund):
Hangout Responding to Gavin Ortlund on Servetus
Fisher has produced three volumes reproducing the relevant writings from Calvin, Servetus, et al. on his trial, execution, and aftermath (two more volumes are forthcoming).
The Calvin Servetus Sourcebook:
Volume 1: Servetus Trial Documents and Exhibits
Volume 3: Beza’s The Life of Calvin and Bolsec’s Life of Calvin
