What is the basis for the disagreement between luther and zwingli?

The main basis for disagreement between Luther and Zwingli was their interpretation of the Eucharist or Communion. Luther believed in the doctrine of consubstantiation, which suggests that the bread and wine used in Communion become the actual body and blood of Christ. Zwingli, on the other hand, believed in the idea of Memorialism, which suggests that the bread and wine are merely symbols of the body and blood of Christ.

This disagreement caused a big schism within the Protestant Reformation movement, with Lutherans on one side and the Swiss Reformed on the other. Additionally, Luther and Zwingli had different views on the role of the church and their interpretation of Scriptures. Luther emphasized the authority of the church and the sacraments, while Zwingli believed that Christians should simply rely on the Bible as their ultimate authority.

Overall, the disagreement between Luther and Zwingli was largely rooted in differing interpretations of key Christian beliefs and Scriptures.
