Martin Luther’s 95 Theses (1517)

October 31 also marked the arrival of the Protestant Reformation. Martin Luther posted his 95 Theses on the door of the Wittenberg Castle Church on the last day of October, 1517. He questioned the Catholic Church’s practices and caused the birth of a religious revolution. His courageous act changed the religious and cultural order in Europe. It paved the way for theological discussions and reforms that lasted for centuries.

Halloween’s ancient Celtic roots

The playful aspect of October 31 can be traced back to the Celtic festival of Samhain. This festival signified the end of the harvest time and the start of winter. The Celts thought that the barrier between the living and the dead was the thinnest on that night, thus allowing the spirits to roam freely. The festival underwent many changes due to the influence of Christianity and eventually became All Hallows' Eve, which was later shortened to Halloween. It is a festival that is now celebrated all over the world with costumes, parties, and pumpkins.

October 31 knits together stories of power, faith, culture, and transformation. It reminds everyone that even a day known for masks and mischief carries layers of meaning. October 31 is a mix of tragedy, change, and timeless human spirit.
