Ecclesiastical Communio: a Sign, the Task, and Ecumenical Challenges

Posaborska ekleziologija stoji čvrsto na poziciji naglašavanja i definiranja Crkve kao zajednice Božjeg Naroda u kojoj je zajedništvo (communio, communitas) temeljna svetopisamska kategorija i polazište. Ali, koje je izvorište te koncepcije i takvog gledanja? Govoreći o tome ne može se zaobići pojmove kao što su: Presveto Trojstvo, unutarnji, zajedničarski, zajednički život i djelovanje Presvetoga Trojstva, te poslanje Sina i Duha Svetoga, te osnivanje Crkve i njezino poslanje u svijetu. U konačnici, i ekumenizam i cjelokupno ekumensko gibanje teži i usmjeren je da se, konačno, sve kršćanske Crkve i crkvene zajednice sve više otvore i porade da se ostvari COMMUNIO, zajednica Kristovih učenika koja će biti Crkva, Crkva Kristova, tj. »Una, Sancta, Catholica et Apostolica«, kako ispovijedamo u Vjerovanju. Taj cilj, postizanje punog, euharistijskog zajedništva jest znak, zadaća i najveći izazov suvremenom kršćanstvu i ono što obilježava teološko istraživanje i ekumenski dijalog danas. Dijalog i communio koji opstoji i koji se ostvaruje unutar Presvetoga Trojstva, prelazi i jest dar i poslanje koje je primila Crkva i koje treba ostvariti i posvjedočiti, oživotvoriti i uprisutniti u zajednicu ljudskoga roda. Time će Crkva, u konačnici, biti ono što Lumen gentium, za nju i kaže i želi da se dogodi: »... Crkva je u Kristu kao sakrament ili znak i oruđe najtješnjeg sjedinjenja s Bogom i jedinstva cijeloga ljudskog roda.« (br. 1).Post-conciliar ecclesiology firmly emphasizes and defines the Church as community of people of God, in which communion (communio, communitas) is fundamental, biblical category and starting point. What is the source of that conception and a standpoint? Keeping it in mind, one can not avoid the terms such as: the Holy Trinity, internal, communitarian, community life as well as activity of the Holy Trinity, the mission of the Son and the Holy Spirit, and establishment of the Church and its mission in the world. The entire ecumenical movement strives towards a permanent opening of all the Christian Churches and Church communities to make an effort in order to realize communio, a community of Christ\u27s disciples, a community which will be the Church, Christ\u27s Church, i.e., »One, holy, catholic and apostolic«, as it is stated in the Creed. That aim- realization of a full, eucharistic communion is the sign, a task and the biggest challenge to contemporary Christianity as well as for the entire contemporary theological research and ecumenical dialogue. Dialogue and communion, which exist and are realized within the Holy Trinity, the Church has been receiving as a gift and its mission. The Church has to witnesss it and to put it into practice. It has to make it alive and present within the entire community of human race. By doing so, the Church will eventually fulfill the expectations of the Vatican II, stated in its document Lumen gentium: »...the Church is in Christ like a sacrament or as a sign and instrument both of a very closely knit union with God and of the unity of the whole human race...« (LG I.)
