Even as Pope Francis and Catholic leaders from around the world debate ways to make the Catholic Church more inclusive, Newark Archbishop John Myers has given his priests strict guidelines on refusing Communion to Catholics who, for example, support gay marriage or whose own marriage is not valid in the eyes of the church. In the two-page memo, Myers also orders parishes and Catholic institutions not to host people or organizations that disagree with church teachings. He says Catholics, “especially ministers and others who represent the Church, should not participate in or be present at religious events or events intended to endorse or support those who reject or ignore Church teaching and Canon Law.”
