The village church
Most people in western Europe belonged to the Roman Catholic church in the Middle Ages. The church was at the centre of everything that went on. Babies were baptised by the priest in the church. Young couples were married at the church door. The dead were buried in the church yard. People were supposed to go to Mass (the church service) on Sundays and the main "holy days". These were the only days off work that they got.
All men and women believed in Heaven and Hell. Rich people left land and money to the church in their wills because they hoped it would help them get into Heaven. The church used the money to look after the old and sick.
Village priests were simple men. They could usually just manage to read, and knew enough Latin to say the Mass. Priests were not supposed to marry, but a lot of them did have wives. Most priests must have looked and talked like the peasants around them.
