“Depends on where. In some strongly Catholic countries like Poland it wasn’t...”
The Catholic Church, before there were nation states was the center of political and religious power. “State religion” in the context of my post mainly referred to US States, post 1776.
In the 16th century an official edict of toleration for all Abrahamic religions was issued, but it was repealed in the 17th century when Catholics were forbidden to convert to Protestantism (never read that it was actually enforced).
In any case, Poles have always had a strong anti-authoritarian bias.
