Reformation Sunday — The Church Always Reforming
Commemorating the Reformation's legacy while embracing its ongoing call to renew the church in every generation.
Last Sunday in October (near October 31)
Overview
Reformation Sunday, observed on the last Sunday in October, commemorates Martin Luther's posting of his 95 Theses on the door of the Castle Church in Wittenberg on October 31, 1517. This event is traditionally considered the catalyst of the Protestant Reformation, though the seeds of reform had been planted by earlier figures like John Wycliffe, Jan Hus, and Erasmus of Rotterdam.
Luther's initial protest was relatively narrow — he objected primarily to the sale of indulgences and related abuses. But the theological questions he raised — about the authority of Scripture, the nature of salvation, and the priesthood of all believers — rapidly expanded into a full-scale reconsideration of Western Christianity. The resulting movement produced the Lutheran, Reformed, Anglican, and eventually Baptist, Methodist, and Pentecostal traditions that now constitute the majority of Protestant Christianity.
For church leaders, Reformation Sunday offers a chance to educate the congregation about their theological heritage. Many modern Christians, particularly in non-denominational settings, have little knowledge of the Reformation — how it happened, what it accomplished, and what the ongoing call to be 'reformed and always reforming' means for the church today. The day also invites honest reflection: the Reformation was necessary, but it also fractured the church. How do we honor the Reformers' courage while pursuing the unity for which Jesus prayed?
Denomination Perspectives
How different traditions observe Reformation Sunday
Catholic
Catholic parishes do not observe Reformation Sunday, as October 31 is the Vigil of All Saints. However, in the ecumenical spirit of Vatican II, some Catholic communities participate in joint commemoration events with Lutheran and other Protestant partners. Pope Francis' participation in a joint Catholic-Lutheran commemoration in 2016 marked a significant step toward mutual understanding. The Catholic Church acknowledges the legitimate concerns that sparked the Reformation while maintaining that the response was ultimately schismatic.
Protestant
Lutheran churches naturally emphasize Reformation Sunday, often featuring Luther's hymn 'A Mighty Fortress Is Our God,' readings from Romans on justification by faith, and educational presentations about Luther and the Reformers. Reformed and Presbyterian churches celebrate their own Reformation heritage through the Five Solas and the writings of John Calvin and John Knox. Many Protestant churches use the day for ecumenical dialogue, acknowledging both the Reformation's gifts and its wounds.
Orthodox
The Orthodox Church does not observe Reformation Sunday, as the Protestant Reformation was a Western phenomenon that did not directly affect the Eastern churches. However, Orthodox theologians engage with Reformation theology in academic settings, and some Orthodox leaders participate in ecumenical conversations about the Reformation's legacy and the ongoing pursuit of Christian unity.
Non-denominational
Non-denominational churches may or may not acknowledge Reformation Sunday. Those that do often use it as an educational opportunity to explore the roots of Protestant theology — sola Scriptura, sola fide, sola gratia — and their relevance today. Some churches use the occasion to teach church history more broadly, helping members understand how their faith tradition fits into the larger story of Christianity.

Display the Five Solas (Sola Scriptura, Sola Fide, Sola Gratia, Solus Christus, Soli Deo Gloria) visually and explain each one briefly during the service.

Be sensitive to the ecumenical implications — celebrate the Reformation's gifts without denigrating Catholic or Orthodox traditions. Frame it as a call to renewal, not a victory celebration.
