19th-century scholarly research into the liturgy of the first centuries showed how far the current liturgy had departed from the earlier practice, where the congregation was actively involved, responding and singing in its own language. But now the mass was in Latin, a language most people did not understand, and the congregation observed in silence the ritual performed by the priest at the altar. This realization inspired a modest movement to get the congregation involved in the mass, to get them to respond and to sing those parts of the mass that belonged to them. Some even proposed that Latin be replaced by the language of the people. The liturgical movement was greeted with considerable caution by Church authorities. In the early 1950s, there was a significant reform of the ceremonies of Holy Week, but by the early 1960s, little else had changed. Ecumenical movement The term “ecumenism” came into use in the 20th century to refer to efforts – initially among Protestants – towards the reunification of Christians. Initially, the Catholic Church was hostile to the ecumenical movement. The traditional position of the Church was that Catholics had nothing to learn from Protestants and the only way Christian unity would happen was when non-Catholics returned to the Catholic Church. Collaboration with non-Catholics was forbidden. By the early 1950s, there was a modest ecumenical movement within the Catholic Church, but it had little support from the authorities. Biblical movement Pope Pius XII's 1943 encyclical Divino afflante spiritu gave a renewed impetus to Catholic Bible studies and encouraged the production of new Bible translations from the original languages. This led to a pastoral attempt to get ordinary Catholics to re-discover the Bible, to read it, to make it a source of their spiritual life. This found a response in very limited circles. By 1960, the movement was still in its infancy. Ressourcement and Nouvelle théologie By the 1930s, mainstream theology based on neo-scholasticism and papal encyclicals was being rejected by some theologians as dry and uninspiring. Thus, was born the movement called ressourcement, the return to the sources: basing theology directly on the Bible and the Church Fathers. Some theologians also began to discuss new topics, such as the historical dimension of theology, the theology of work, ecumenism, the theology of the laity, the theology of “earthly realities”. All these writings in a new style came to be called “la nouvelle
