From the USCCB – June 4, 2018 – Today, the U.S. Supreme Court decided the case of Masterpiece Cakeshop v. Colorado Civil Rights Commission. The case involves a Christian baker named Jack Phillips who declined in 2012 to create a custom wedding cake for a same-sex ceremony. State officials sought to compel Phillips to create such cakes under Colorado’s public accommodations law. The Supreme Court ruled 7-2 in favor of Phillips under the Free Exercise Clause of the First Amendment to the U.S. Constitution. Archbishop Joseph E. Kurtz of Louisville, Chairman of the Committee for Religious Liberty, Archbishop Charles J. Chaput, O.F.M. Cap., of Philadelphia, Chairman of the Committee on Laity, Marriage, Family Life and Youth, and Bishop James D. Conley of Lincoln, Chairman of the Subcommittee for the Promotion and Defense of Marriage of the U.S. Conference of Catholic Bishops (USCCB), issued the following joint statement: “Today’s decision confirms that people of faith should not suffer discrimination on account of their deeply held religious beliefs, but instead should be respected by government officials. This extends to creative professionals, such as Jack Phillips, who seek to serve the Lord in every aspect of their daily lives. In a pluralistic society like ours, true tolerance allows people with different viewpoints to be free to live out their beliefs, even if those beliefs are unpopular with the government.” The USCCB filed an amicus curiae brief supporting Masterpiece Cakeshop, which can be found here: http://www.usccb.org/about/general-counsel/amicus-briefs/upload/16-111-tsac-USCCB.pdf.        

PA Speaker of the House Mike Turzai (R-Allegheny) is praising a decision by the U.S. Court of Appeals which will uphold the traditional practice of having a session-opening prayer. “We are pleased that the Third Circuit has found that our prayer complies with the United States Constitution,” Turzai said, “and has issued a precedent setting decision entirely in the House’s favor. As a result, we expect the House to be able to resume its tradition of welcoming guest chaplains as it has in the past.” In 2016 a group of atheists and other non-believers sued the House, claiming their exclusion as guest chaplains violated the Constitution. The plaintiffs also challenged the presiding officer’s traditional request to rise for the prayer and the pledge to the flag. Last year, a federal judge in Harrisburg ruled in favor of the plaintiffs and limited the practice to member-led prayers. But the House appealed. Late last month a three-judge panel of the Third Circuit ruled in the House’s favor on all counts. “By a 2-1 vote the panel held the House’s prayer practices were constitutional because they fit within the long history of legislative prayer in this country,” Turzai said. “The majority explained that ‘only theistic prayer can satisfy the historical purpose of appealing for divine guidance in lawmaking.’” Turzai said the panel ruled 3-0 that it is constitutional and not coercive to request that guests stand for the prayer and the pledge.
