Abstract

A double structure, hierarchical and fraternal, belongs to the essence of the Church. It is not easy, however, to live and to harmonise doctrinally order and communion. The article tests the idea of pericoresi, or «circumincession», which in origin is a Christological concept, to see whether it also helps ecclesiological reflection. After examining patristic, medieval and doctrinal tradition, the article outlines a Trinitarian ecclesiology, noting its strengths as well as its limits. The conclusion applies the results to the study of different states of life in the Church
