Is it possible to consider that in the Middle Ages opponents of the church were considered as enemies of the state?

Here you need to clearly understand that in medieval times, the church and the state were actually one whole. The government manipulated society using the church as a tool. Church canons were considered above all. All opponents of the church were accused of heresy, which means they were punished by the Inquisition and very severely. Everything is very simple here, if the opponents of the church conveyed their ideas to the broad masses, then the authority of the church would be shaken, which means that the power, which was held at the expense of the church, would be shaken. Mass uprisings could have occurred, and therefore all opponents of the church were considered opponents of the state.
