All Americans share responsibility for public safety. This requires reasonable measures to regulate the sale and use of lethal weapons. As faithful citizens – Catholic theologians, priests, sisters and social justice advocates – we join our bishops, the Catholic Health Association and Catholic Charities USA in calling for common-sense reforms to address the epidemic of gun violence in our nation. Pro-life citizens and elected officials have a responsibility to show greater moral leadership and political courage when it comes to confronting threats to the sanctity of life posed by easy access to military-style assault weapons and high capacity magazines. Members of Congress who take pride in their pro-life stance and appeal to family values have no excuse for inaction, and neither do any of us who share a firm commitment to these values. We especially encourage our fellow Catholics in Congress, including prominent leaders such as House Speaker John Boehner, to stand up to the National Rifle Association and other gun lobbyists who choose to obstruct sensible reforms. Catholics who earn an “A” rating from the NRA – including Republicans like Speaker Boehner and Rep. Paul Ryan and Democratic lawmakers such as Sen. Joe Donnelly and Sen. Heidi Heitkamp – should not put powerful special interests before the common good. We urge you to reflect on the wisdom in our church’s call for a “consistent ethic of life” as you consider legislation in the coming months that can provide greater protection for our families and communities. Thousands of Catholics will gather this week for the annual “March for Life” in Washington to speak out against the tragedy of abortion. Our faith and our Church call us to remember, as we reflect on our most recent massacres, that the defense of human dignity extends beyond protecting life in the womb. Gun violence demeans human life and tears communities apart. There have been more than 70 mass shootings since the January 8, 2011, massacre in Tucson, Arizona. More than 900 people have been killed with guns since the Newtown tragedy. The U.S. Conference of Catholic Bishops recently renewed their call for measures to address gun violence by echoing their 2000 statement, Responsibility, Rehabilitation and Restoration: A Catholic Perspective on Crime and Criminal Justice. Bishops have called for “measures that control the sale and use of firearms” and “sensible regulations of handguns.” The Vatican’s Pontifical Council for Justice and Peace, in a 1994 document, “The International Arms Trade,” urges political leaders “to impose a strict control on the sale of handguns and small arms” and states that “limiting the purchase of such arms would certainly not infringe on the rights of anyone.” All of us need to work against the glorification of violence, remedy our inadequate mental health services and address the breakdown of family support structures. No single law or set of regulations will prevent all tragedies, but the complexity of this urgent challenge must not be an excuse for protecting the status quo when it comes to regulating the sale and use of lethal weapons. President Obama and Members of Congress can honor the memories of those killed in Newtown, Conn., and work to prevent future tragedies by acting now. Signed, Miguel H.
