There are many holidays that we simply forget to celebrate. In fact, there are many holidays that we simply did not know existed. October 31st is just such a holiday. While most of the people around us talk of Halloween and trick or treating, there is another significant holiday that takes place on October 31st. On October 31st, 1517 a young monk and professor of Old Testament walked to his church and nailed onto the door an invitation for an academic debate. Come next Sunday and discover (or maybe rediscover) a truly important Holiday in the life of Christ’s universal Church.
