When did the split between the Catholic Church and the Protestant Church occur?

Formal split began in 1517 when Martin Luther published the Ninety-Five Theses, sparking the Protestant Reformation. Over the next century doctrinal, political, and liturgical divisions widened, with key moments including the 1521 Diet of Worms, the Council of Trent (1545 to 1563), the 1555 Peace of Augsburg, and the 1648 Peace of Westphalia.

Deeper Insights

Major turning point occurred in 1517 when Martin Luther published the Ninety-Five Theses, prompting widespread calls for reform.

Early precursors: Figures such as John Wycliffe and Jan Hus challenged church practices in the 14th and 15th centuries, creating earlier dissent.
Key reform milestones: 1517 Luther’s theses; 1521 Diet of Worms where reformers were condemned; 1534 Act of Supremacy established a separate Church of England under royal authority.
Catholic response: The Council of Trent from 1545 to 1563 clarified Catholic doctrine and enacted internal reforms as part of the Counter-Reformation.
Legal and political settlement: The Peace of Augsburg in 1555 and the Peace of Westphalia in 1648 institutionalized confessional divisions across much of Europe, making the split effectively permanent in political terms.
Theological divide: Protestant emphases on sola fide and sola scriptura contrasted with Catholic affirmation of papal authority and seven sacraments, producing enduring doctrinal separation.
