Read the full account

In the early 1550s Calvin’s predestination controversies, including the Bolsec affair, produced expulsions and hardened polemical print.

Context

Doctrine and exile intertwine. Cambridge Companion and Britannica independently narrate Bolsec and related predestination fights.

John Calvin’s documented role is bounded by other offices and collaborators named in the sources below.

Conventional years are 1509–1564. Surviving public files are later museum pages, consistory editions, Meeter Center collections, and encyclopedias. Calvin did not typeset those later pages.

What the sources establish

The Cambridge Companion and Britannica independently describe the Bolsec predestination controversy.

Established: Bolsec-era predestination conflict led to expulsion and polemics. Not established: a unique sermon-attendance series.

John Calvin did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. Bolsec is not Servetus. Keep predestination expulsion off 27 October 1553.
