One of the essential problems in the relationship between Catholic-Orthodox churches is the difference in the interpretation of the current forms of the primacy in the Church of the Bishop of Rome. Contemporary studies on the essence and on the method of accom-plishing this service on behalf of the universal Church’s unity assumed new dynamics after the publication of the ecumenical encyclical letter of John Paul II – Ut unum sint. The Pope addressed and requested the pastors and theologians to establish with him a “patient and fraternal dialogue” (see US 95-96), for both parties to strive to achieve “the forms in which this ministry may accomplish a service of love recognized by all concerned” (US 95). The contemporary Orthodox theologians, based on the results of historical studies, are con-vinced that the idea of the Roman primacy has been always presented in the theological awareness of the Christian East. The Eastern Churches do not negate the primacy of the Pope, as the Bishop of Rome, and as the first bishop of the whole Church. Recognizing the primacy of the Holy See as an incontestable historical fact, the Orthodox theologians see the crucial problem in the determination of its nature. They do not accept the primacy in the juridical sense.
Intellectual and spiritual formation of Joseph Ratzinger - Pope Benedict XVI - requires talk about the process of his development. The article refers to the most overlooked phase of the young Ratzinger, who moves from the position of a progres-sive and sometimes irresponsible theorizing academic theologian to the position of a thinker grounded in the community of faith, becoming the guardian and teacher of Christian doctrine in line with the spirit and tradition of the Church. A lot of light on the change in the attitude of the German professor sheds the preparatory phase to the Second Vatican Council and its debates, as well as the unpleasant experience of the student revolt in 1968, which finds our professor in Tübingen. And in this way the liberal German theologian grows into to an outstanding Catholic theologian of the universal Church.
