Reformation Sunday remembers Martin Luther’s commitment to practicing Christianity in Jesus. October 31, 1517 was the day the German monk nailed his Ninety-five Theses on the door of the All Saints’ Church in Wittenberg, Germany, an Electorate of Saxony in the Holy Roman Empire.
Available data suggests that October 31 was when Luther sent his work to Albert of Brandenburg, the Archbishop of Mainz. This has been verified; nowadays, it is regarded as the start of the Reformation.
The Holiday is a significant on for both Lutheran and Calvinist churches, although other Protestant communities also tend to commemorate this day. The Catholic Church recognized it only recently, and often sends its official representatives in ecumenical spirit to various commemoration events held by Protestants. It is lawfully and officially recognized in some states of Germany and sovereign countries of Slovenia and Chile. In addition, countries like Switzerland and Austria provide specifics in laws pertaining to Protestant churches, while not officially proclaiming it a nationwide holiday.
The Protestant Christian religious holiday is celebrated alongside All Hallows’ Eve (Halloween) during the triduum of Allhallowtide, in remembrance of the onset of the Reformation.
