According to Roberto Bosca, a historian at Austral University in Buenos Aires, Jorge Bergoglio (later Pope Francis) had "a reputation as an opponent of liberation theology during the 1970s"; he "accepted the premise of liberation theology, especially the option for the poor, but in a 'nonideological' fashion." Before becoming Pope, Bergoglio said, "The option for the poor comes from the first centuries of Christianity. It's the Gospel itself. If you were to read one of the sermons of the first fathers of the Church, from the second or third centuries, about how you should treat the poor, you’d say it was Maoist or Trotskyist. The Church has always had the honor of this preferential option for the poor. ...At the Second Vatican Council the Church was redefined as the People of God and this idea really took off at the Second Conference of the Latin-American bishops in Medellín." Bosca said Bergoglio was not opposed to liberation theology itself but to "giving a Catholic blessing to armed insurgency", specifically the Montoneros, who claimed liberation theology as part of their political ideology.
