Ut unum sint


Ut unum sint is an encyclical on ecumenism by Pope John Paul II of 25 May 1995. It was one of 14 encyclicals he issued, and Cardinal Georges Cottier, Theologian Emeritus of the Pontifical Household, was influential in its drafting.
Like many encyclicals, this one derives its title from its "incipit" or first few words. These words are taken from the prayer of Jesus "at the hour of his Passion" in the Vulgate translation of the Gospel according to John. The document deals with the Catholic Church's relations with the Eastern Orthodox Church and other Christian ecclesial communities. It reiterates that unity of these two sui juris churches is essential, as well as further dialogue and unity with the Protestant churches. This document shows that the Catholic Church is officially committed to unity. It has become a common piece of study in ecumenical classes.
Although it builds on the Second Vatican Council's decree, Unitatis redintegratio, and pays testimony to the work of Popes Paul VI and John Paul I, Ut unum sint was the first encyclical ever devoted exclusively to the ecumenical imperative. In this groundbreaking exercise of the papal magisterium, Pope John Paul affirmed that the ecumenical commitment made at Vatican II was irreversible. He taught his fellow Catholics that the quest for Christian unity ought to be sustained both internationally and in the local churches.

Summary

Paragraph 9 summarises the place of Christian unity in the Church's thinking:
In paragraph 54, the Pope wrote that "the Church must breathe with her two lungs!"
In paragraph 79, five subjects are noted to be "in need of fuller study before a true consensus of faith can be achieved":
After an introduction, the encyclical's three chapters are entitled:
  • Chapter 1 - The Catholic Church's Commitment to Ecumenism
  • Chapter 2 - The Fruits of Dialogue
  • Chapter 3 - Quanta Est Nobis Via?
These sections are followed by an exhortation calling on "everyone to renew their commitment to work for full and visible communion".
The ultimate goal of the ecumenical movement is to "re-establish full visible unity among all the baptized".
"It is understandable how the seriousness of the commitment to ecumenism presents a deep challenge to the Catholic faithful. The Spirit calls them to make a serious examination of conscience."
