Óscar Arnulfo Romero y Galdámez (15 August 1917 – 24 March 1980) was a prelate of the Catholic Church in El Salvador, who served as the fourth Archbishop of San Salvador. He spoke out against poverty, social injustice, assassinations, and torture. In 1980, Romero was assassinated while offering Mass in the chapel of the Hospital of Divine Providence.
Pope Francis stated during Romero’s beatification that “His ministry was distinguished by a particular attention to the most poor and marginalized.” Hailed as a hero by supporters of liberation theology inspired by his work, Romero, according to his biographer, “was not interested in liberation theology” but faithfully adhered to Catholic teachings on liberation and a preferential option for the poor, desiring a social revolution based on interior reform. His spiritual life drew much early on from the spirituality of Opus Dei. While seen as a social conservative at his appointment as Archbishop in 1977, he was deeply affected by the murder of Rutilio Grande a few weeks after his own appointment and became more of a social activist from that time forward.
In 1997, Pope John Paul II bestowed upon Romero the title of Servant of God, and a cause for beatification and canonization was opened for him. The cause stalled, but was reopened by Pope Benedict XVI in 2012. He was declared a martyr by Pope Francis on 3 February 2015, paving the way for his beatification which took place on 23 May 2015.
