VATICAN CITY - It's now been one year since Jorge Bergoglio, of Argentina, was elected pope, choosing the name Francis. 

Pope Francis became the first pontiff from the Americas, and the first from outside Europe in more than a millennium. 

In his first year, the pope proved he's not shy about addressing social issues in the Catholic Church. While he has not changed church doctrine, he has started a dialogue about controversial topics, such as abortion, gay marriage and contraception. 

New York Archbishop Timothy Cardinal Dolan joined Archbishop Joseph Kurtz, who is the president of the U.S. Conference of Catholic Bishops, in holding a Mass at St. Patrick's Cathedral in Manhattan to honor Pope Francis’s anniversary.
