Which of the ideas of yang goos caused the greatest irritation of Rome and the emperor?

The trade in church offices and paid indulgences, the church’s ownership of significant land plots, in my opinion, should have caused quite strong indignation in Rome, because they deprived the church of significant income.

Speaking out against the privileges of the clergy, the intervention of the church in state and secular life, also, for quite understandable reasons, could not cause anything but anger among the churchmen.

The emperor could seriously not like the use of an understandable folk language in church services, because this was a step towards the self-determination of the peoples of the empire.

Both the emperor and Rome did not like the idea that each person could independently interpret the Holy Scriptures. And this is perhaps the only thing I can agree with. An independent interpretation of the Bible will not bring you closer to the truth, but the fact that the church and society will constantly split up because of this is a fact. This is what happens in Protestantism. They do not have a single church, there are different trends and trends (Lutherans, Anglicans, Calvinists, etc.).
