1. Simony: Bishops were often accused of selling church offices and positions for money. This practice was condemned by the church, but it remained prevalent throughout the Middle Ages.
2. Pluralism: Bishops often held multiple church offices at once, which prevented them from properly fulfilling their duties in any one diocese. This practice also contributed to the problem of absenteeism, as bishops who held multiple offices were often absent from their dioceses.
3. Worldliness: Bishops were often seen as being too interested in worldly pursuits, such as wealth, power, and prestige. This led to accusations that they were neglecting their spiritual duties and responsibilities.
4. Corruption: Bishops were often accused of corruption, such as nepotism, bribery, and extortion. These accusations contributed to the decline of the Church's authority and prestige in the late Middle Ages.
5. Lack of Education: Bishops were often criticized for their lack of education and theological knowledge. This made it difficult for them to effectively lead and teach their dioceses.
6. Political Involvement: Bishops were often involved in political affairs and power struggles, which diverted their attention from their religious duties.
These complaints about bishops contributed to the growing criticism of the Church in the late Middle Ages and laid the foundation for the Protestant Reformation.
