Every year, the serfs had to donate 1/10 of their crops to the Church, they believed this would make them a good Christian.
The Church helped give the people a sense of community because both the Church and the families of serfs worked together to make sure everyone made it through each year.
Kings were usually illiterate, they had bishops, abbots, and clerks to write down documents and keep record because they couldn't do it themselves.
St. Gregory issued a document saying that the pope had more power than the king and if any government official opposed against it, they would be excommunicated. King Henry IV fought against it and lost the support of all of his people.
The Church gave the people teachings of rules and principles on how to live the perfect life and have a happy life after death.
Clergies were well-respected by everyone because they were representatives of God and had religiously helped the people for years.
