By David Paul Deavel, Catholic World Report - For Catholics, the end of October marked the beginning of Hallowtide—All Hallows’ Eve, or Halloween, All Hallows (All Saints), and All Souls. For Protestant Christians who have maintained some connection with the first Protestants, October 31 is celebrated as Reformation Day, which commemorates Martin Luther’s posting of his Ninety-five Theses... I grew up celebrating Halloween (the secular version) and, because my parents started attending a Calvinist congregation (Christian Reformed) when I was young, we sometimes attended Reformation Day services.
