One of the Collects in the Missal that can be used for a Mass "for the unity of Christians" reads as follows:
Almighty ever-living God, who gather what is scattered and keep together what you have gathered, look kindly on the flock of your Son, that those whom one Baptism has consecrated may be joined together by integrity of faith and united in the bond of charity.In the first instant, the Octave prompts us to reflect on the nature of the unity of the Church, perhaps as expressed in the Catechism of the Catholic Church n.813:
The Church is one because of her source: "the highest exemplar and source of this mystery is the unity, in the Trinity of Persons, of one God, the Father and the Son in the Holy Spirit." The Church is one because of her founder: for "the Word made flesh, the prince of peace, reconciled all men to God by the cross, . . . restoring the unity of all in one people and one body." The Church is one because of her "soul": "It is the Holy Spirit, dwelling in those who believe and pervading and ruling over the entire Church, who brings about that wonderful communion of the faithful and joins them together so intimately in Christ that he is the principle of the Church's unity." Unity is of the essence of the Church:
What an astonishing mystery! There is one Father of the universe, one Logos of the universe, and also one Holy Spirit, everywhere one and the same; there is also one virgin become mother, and I should like to call her "Church."
The Octave of Prayer for Christian Unity also brings to my mind the address of Pope Benedict XVI in Cologne, during his meeting with representatives of other Christian denominations. In that address, Pope Benedict drew attention to the significance of Baptism as the source of a shared sense of fraternity arising from dialogue between Christians of different denominations, suggesting that we should not underestimate this significance:
I feel the fact that we consider one another brothers and sisters, that we love one another, that together we are witnesses of Jesus Christ, should not be taken so much for granted. I believe that this brotherhood is in itself a very important fruit of dialogue that we must rejoice in, continue to foster and to practice.
Among Christians, fraternity is not just a vague sentiment, nor is it a sign of indifference to truth. As you just said, Bishop, it is grounded in the supernatural reality of the one Baptism which makes us all members of the one Body of Christ (cf. I Cor 12: 13; Gal 3: 28; Col 2: 12).
Together we confess that Jesus Christ is God and Lord; together we acknowledge him as the one mediator between God and man (cf. I Tm 2: 5), and we emphasize that together we are members of his Body (cf. Unitatis Redintegratio, n. 22; Ut Unum Sint, n. 42).
Based on this essential foundation of Baptism, a reality comes from him which is a way of being, then of professing, believing and acting. Based on this crucial foundation, dialogue has borne its fruits and will continue to do so.Pope Benedict went on to suggest a way towards that "integrity of faith" and "unity in the bond of charity" to which our Collect refers. There is a particular reference to the situation of ecumenical dialogue in Germany in 2005, but the thoughts expressed are just as relevant today:
May I make a small comment: now, it is said that following the clarification regarding the Doctrine of Justification, the elaboration of ecclesiological issues and the questions concerning ministry are the main obstacles still to be overcome. In short, this is true, but I must also say that I dislike this terminology, which from a certain point of view delimits the problem since it seems that we must now debate about institutions instead of the Word of God, as though we had to place our institutions in the centre and fight for them. I think that in this way the ecclesiological issue as well as that of the "Ministerium" are not dealt with correctly.
The real question is the presence of the Word in the world. In the second century the early Church primarily took a threefold decision: first, to establish the canon, thereby stressing the sovereignty of the Word and explaining that not only is the Old Testament "hai graphai", but together with the New Testament constitutes a single Scripture which is thus for us the master text.
However, at the same time the Church has formulated an Apostolic Succession, the episcopal ministry, in the awareness that the Word and the witness go together; that is, the Word is alive and present only thanks to the witness, so to speak, and receives from the witness its interpretation. But the witness is only such if he or she witnesses to the Word.
Third and last, the Church has added the "regula fidei" as a key for interpretation. I believe that this reciprocal compenetration constitutes an object of dissent between us, even though we are certainly united on fundamental things.
Therefore, when we speak of ecclesiology and of ministry we must preferably speak in this combination of Word, witness and rule of faith, and consider it as an ecclesiological matter, and therefore together as a question of the Word of God, of his sovereignty and humility inasmuch as the Lord entrusts his Word, and concedes its interpretation, to witnesses which, however, must always be compared to the "regula fidei" and the integrity of the Word. Excuse me if I have expressed a personal opinion; it seemed right to do so.At this time , with the martyrdom of Christians never far from the headlines, the observation of n.84 of Pope John Paul II's Encyclical Ut Unum Sint, that a witness to death represents a perfection of communion between Christians, gains added relevance:
In a theocentric vision, we Christians already have a common Martyrology. This also includes the martyrs of our own century, more numerous than one might think, and it shows how, at a profound level, God preserves communion among the baptized in the supreme demand of faith, manifested in the sacrifice of life itself. The fact that one can die for the faith shows that other demands of the faith can also be met. I have already remarked, and with deep joy, how an imperfect but real communion is preserved and is growing at many levels of ecclesial life. I now add that this communion is already perfect in what we all consider the highest point of the life of grace, martyria unto death, the truest communion possible with Christ who shed his Blood, and by that sacrifice brings near those who once were far off (cf. Eph 2:13).
