Pope Francis on Sunday canonized Pope Paul VI and murdered Salvadoran Archbishop Oscar Romero, declaring the two new saints before a crowd of 70,000 at the Vatican. He called Paul, who was pope from 1963 to 1978, a "prophet of a church turned outwards." Today the former pope is best known for his work in the Second Vatican Council and his authorship of the 1968 encyclical Humanae Vitae (On Human Life). Francis praised Romero's sacrificial life to "be close to the poor and his people." The archbishop was murdered while giving a Mass in El Salvador in 1980, shot as he spoke of "the benefits of human dignity, brotherhood, and freedom across the earth." He was killed during mass for preaching social justice.
