RELATIONS WITH THE BRETHREN OF THE SEPARATED CHURCHES

24. The Eastern Churches in communion with the Apostolic See of Rome have a special duty of promoting the unity of all Christians, especially Eastern Christians, in accordance with the principles of the decree, "About Ecumenism," of this Sacred Council, by prayer in the first place, and by the example of their lives, by religious fidelity to the ancient Eastern traditions, by a greater knowledge of each other, by collaboration and a brotherly regard for objects and feelings.²⁹

25. If any separated Eastern Christian should, under the guidance of the grace of the Holy Spirit, join himself to the unity of Catholics, no more should be required of him than what a bare profession of the Catholic faith demands. Eastern clerics, seeing that a valid priesthood is preserved among them, are permitted to exercise the Orders they possess on joining the unity of the Catholic Church, in accordance with the regulations established by the competent authority.³⁰

26. Common participation in worship (communicatio in sacris) which harms the unity of the Church or involves formal acceptance of error or the danger of aberration in the faith, of scandal and indifferentism, is forbidden by divine law.³² On the other hand, pastoral experience shows clearly that, as regards our Eastern brethren, there should be taken into consideration the different cases of individuals, where neither the unity of the Church is hurt nor are verified the dangers that must be avoided, but where the needs of the salvation of souls and their spiritual good are impelling motives. For that reason the Catholic Church has always adopted and now adopts rather a mild policy, offering to all the means of salvation and an example of charity among Christians, through participation in the sacraments and in other sacred functions and things. With this in mind, "lest because of the harshness of our judgment we be an obstacle to those seeking salvation" ³¹ and in order more and more to promote union with the Eastern Churches separated from us, the Sacred Council lays down the following policy.

27. Without prejudice to the principles noted earlier, Eastern Christians who are in fact separated in good faith from the Catholic Church, if they ask of their own accord and have the right dispositions, may be admitted to the sacraments of Penance, the Eucharist and the Anointing of the Sick. Further, Catholics may ask for these same sacraments from those non-Catholic ministers whose churches possess valid sacraments, as often as necessity or a genuine spiritual benefit recommends such a course and access to a Catholic priest is physically or morally impossible.³³

28. Further, given the same principles, common participation by Catholics with their Eastern separated brethren in sacred functions, things and places is allowed for a just cause.³⁴

29. This conciliatory policy with regard to "communicatio in sacris" (participation in things sacred) with the brethren of the separated Eastern Churches is put into the care and control of the local hierarchs, in order that, by combined counsel among themselves and, if need be, after consultation also with the hierarchs of the separated churches, they may by timely and effective regulations and norms direct the relations among Christians.
