Religious liberty is a much debated issue in recent years. One need only think of the debates around contraception and the affordable care act. Of course, at this time of year we debate whether it is appropriate to sing Christmas carols in school. Then there is the question of whether the First Amendment applies to the majority religion or all religions. That Donald Trump (see my posting from yesterday) would offer a plan to ban Muslims from entering the country, suggest that Muslims could be surveiled, and mosques closed raises issues of religious liberty for whom. In this week's Sightings column Martin Marty lifts up one of the most significant decisions to come out of Vatican II. On December 7, 1965, fifty years ago this past Monday, the Council voted by a landslide to set aside settled Catholic doctrine that held that in countries with a Catholic majority, Catholics should be privileged over other faith traditions. That this was rejected by the church set forth a new day in religious liberty -- but what does this mean? Take a read and offer your thoughts.
