Answer:
Because they were heavily involved in the government
Explanation:
Just like Martin Luther, Erasmus accused the church of abusing his powers. (for example, the church was openly selling indulgence to abolish sins).
At that time, the church was very influential within the government since the kings tend to use people from the church as his 'advisors'. Because of this, it is almost impossible for that society to create laws that banned the abusive practices by the church. So they still allowed them to continue.
