Abstract
One of the most important problems for contemporary Catholicism is its dialogue with the contemporary world. In recent years, the leaders of the Catholic Church have been speaking of this with increasing frequency. The Catholic journal La Civiltà cattolica has even written of the need to found a "theology of dialogue" . The recent papal encyclicals - "Mater et Magistra" , "Pacem in Terris" , and "Ecclesiam suam" - express the effort of the leaders of Catholicism to establish more intimate contacts with the world in which the religious people of today find themselves. It is therefore no accident that this problem of dialogue was taken up in discussions at the Second Ecumenical Council and particularly at its third session held in the autumn of 1964
