wait what? this whole plan is to make the MC look bad by having him go against the holy nation making him an enemy of god yet why are you acting like the most Saturday morning cartoon villain possible with your sneaking around, kidnapping, mass killings and fanatic ravings? all you will do is turn the people against the bishop and make the pope disavow him and the MC will just become more popular for taking down the corrupt within the church.
you should have done the kidnapping silently and without them expecting it and only once the girl was back in the YS capital under constant supervision should you start the shit flinging, at that point the pope is forced to take the bishops side, as things stand now the pope can still disavow and this whole thing falls apart...
