A day to remember missionary martyr Mgr. Oscar Arnulfo Romero
March 24, the day in which Mgr. Oscar Arnulfo Romero, Archbishop of San Salvador was assassinated in 1980, was chosen 28 years ago by the then Missionary Youth Movement of the Pontifical Mission Societies of Italy to celebrate annually the "Day of prayer and fasting in memory of the missionary martyrs".
The Archbishop, assassinated while celebrating Mass, was beatified on May 23, 2015 and canonized by Pope Francis on October 14, 2018.
