Answer:
Presbyterianism differed from other types of Protestantism primarily in its form of church government. While other Protestant denominations, such as Anglicanism and Lutheranism, had bishops as their leaders, Presbyterian churches were led by elders elected by the congregation. This system of church government, known as "presbyterian polity," emphasized the authority of local churches and their governing bodies, rather than a hierarchical structure with central authority. Additionally, Presbyterianism emphasized the importance of education, particularly in regards to biblical interpretation and theology, which was reflected in the establishment of Presbyterian colleges and seminaries.
