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.

The Meaning of Life by Yevgeny Trubetskoy (1863–1920) is one of the most important works of the religious-philosophical renaissance in Russia. The book addresses the issue of value of human life despite the evidence of evil, violence and moral decline. In order to achieve his aim the Russian thinker referred to the philosophy of all-unity and the category of revelation. However, he understood the latter category in two ways: broad and narrow. In the broad sense the higher meaning of revelation (all-unity) is constantly revealed to humans, which allows them to cognize and develop. In the narrow sense revelation came from Jesus Christ who has revealed the deepest sense of life by means of His paschal mystery. Every human being has a choice to accept or reject the content of the narrow revelation. Such things as collective consciousness, community-based experience, living within church, eucharist, and common responsibility not only for the fellow believers, but also for the whole creation – can help to accept the narrow revelation. The following article discusses also the aspects of natural revelation, revelation in non-christian religions, conditions and characteristics of christian revelation.
