Reformation Day

Reformation Day is a religious holiday celebrated on October 31 in remembrance of the Reformation, particularly by Lutheran and some Reformed church communities. It is a civic holiday in Slovenia (since the Reformation contributed to its cultural development profoundly, although Slovenians are mainly Roman Catholics) and in the German states of Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt, and Thuringia. It is also a national holiday in Chile since 2008.

On October 31, 1517, Martin Luther posted a proposal at the doors of a church in Wittenberg, Germany to debate the doctrine and practice of indulgences. This proposal is popularly known as the 95 Theses, which he nailed to the Castle Church doors. This was not an act of defiance or provocation as is sometimes thought. Since the Castle Church faced Wittenberg's main thoroughfare, the church door functioned as a public bulletin board and was therefore the logical place for posting important notices. Also, the theses were written in Latin, the language of the church, and not in the vernacular. Nonetheless, the event created a controversy between Luther and those allied with the Pope over a variety of doctrines and practices. When Luther and his supporters were excommunicated in 1520, the Lutheran tradition was born. This in turn would later ease the creation of the Reformed and Anabaptist traditions as well.
