On the 31st of October of every year, Protestant Christians observe Reformation Day – a religious holiday that commemorates the onset of the Reformation.
Many speculations apropos the events that occurred on the 31st of October exist; for example, according to Philip Melanchthon, that day in 1517, German monk Martin Luther nailed his theses on the door of a church, specifically, the All Saints’ Church. This conjecture, however, was never confirmed; for there is no other source to substantiate the notion. Available information impart that the 31st of October was the day when the Archbishop of Mainz received the work of Martin Luther, which is now regarded as the inception of the Reformation, alongside Melanchthon’s surmise.
