In early 1962, with no prior warning, Rahner's superiors in the Society of Jesus told him that he was under Rome's pre-censorship, which meant that he could not publish or lecture without advance permission. The objections of the Roman authorities focused mainly on Rahner's views on the Eucharist and Mariology, however the practical import of the pre-censorship decision was voided in November 1962 when, without any objection, John XXIII appointed Rahner a "peritus" (expert advisor) to the Second Vatican Council: Rahner had complete access to the council and numerous opportunities to share his thought with the participants. Rahner's influence at Vatican II was thus widespread, and he was subsequently chosen as one of seven theologians who would develop "Lumen gentium", the dogmatic explication of the doctrine of the Church. The council's receptiveness towards other religious traditions may be linked to Rahner's notions of the renovation of the church, God's universal salvific revelation, and his desire to support and encourage the ecumenical movement.
