Kings... by their divine right? Granted by God? Represented on earth by his priests?
As for defying feudal authority... what on earth is a takeover, if not that?
And soldiers, who are they? When Britain went to war, they had a whole lot of peasants in their forces. Military equipment, back in the ages, was quite often farming tools modified for warfare.
This isn't some peasant revolt that wants self-rule. This is a high-noble (royal) elder priest using the authority vested in him by the Church to expel a non-believer.
Divine right is a concept that came later than the time period BM is based in, and even then secular and ecclesiastical were two very different things. Some random Bishop couldn't just walk into Essex and proclaim that the Earl was no longer Earl, even with a mob. He would have been arrested and executed.
A takeover is a very moot point. Its a King imposing his will on another King. Peasants lawfully raised to constitute an army are totally different than a priest whipping up a mob to oust someone. Its illegal. Hence why you get arrested.
