WHAT YOU'VE LEARNED
A quick recap of today's lesson.
From a belief about heaven to an emperor in the snow, and a pope calling Christians to crusade.
What you need to know
- The Church (capital C) is the whole Christian organisation; a church (small c) is a building.
- The Western Church was headed by the pope. Simplified, the ladder ran pope, archbishops, bishops, priests, ordinary people.
- Medieval people firmly believed heaven and hell were real, and that following the Church's guidance was the only way into heaven.
Have a goYour mate Jo says medieval people obeyed the Church 'because it was just the law'. What would you tell Jo the bigger reason was?
They firmly believed that following the Church's guidance was the only way into heaven and away from hell.
'Just the law' skips what people actually believed: for them, getting into heaven depended on the Church.
- Usually only bishops and priests could read the Latin Bible; doom paintings showed everyone else heaven and hell.
- Excommunication meant being officially shut out of Church services, and people believed it shut you out of heaven too.
- Hoping to guarantee heaven, wealthy people left land and money in their wills, until roughly one third of Europe's land was Church-owned.
Have a goWhich came first: the Church owning lots of land, or people believing in heaven? Say how one led to the other.
The belief came first. Hoping to guarantee heaven, wealthy people left land and money to the Church in their wills.
The land was a result of the belief. Reversing them makes it look as if the Church simply grabbed land and people obeyed because of it.
- In the early medieval period the pope had little power compared with local kings, but it grew, and kings kept contesting it.
- In the 11th century, under Popes Leo IX and Gregory VII, the Church's power rose and kings lost control over their Church.
- In 1077 Henry IV, excommunicated and fearing for his life, spent three days barefoot in the snow begging Pope Gregory VII's forgiveness.
Have a goHenry IV was an emperor. So why did he end up begging a pope for forgiveness?
He had been excommunicated and feared for his life, so he wanted the excommunication lifted.
The Church's power reached up to an emperor, not just villagers. It was a very clear sign to Europe that the Church was a growing power.
- At Clermont in November 1095, Pope Urban II called on Western European Christians to go on crusade.
The big picture
The medieval Church shaped daily life because people firmly believed that following its guidance was the only way into heaven. That belief fed obedience, gifts of land and the fear of excommunication. Papal power started small next to kings, grew (especially in the 11th century) and was always contested, until Pope Urban II called Western European Christians to crusade in 1095. Historians still debate whether Jerusalem was his main aim.
Key points
Worked example
Problem
Explain how people's belief in heaven helped the Church become wealthy.
⚠ Watch out
Thinking the Church was all-powerful from the start. In the early medieval period the pope and the Church had little power compared with local kings. Papal power grew over time, and kings kept contesting it.
Memory hook
Belief sits in the middle of the web: heaven leads to obeying, giving and fearing. And papal power is a tug-of-war with kings: small at first, rising, still contested.
