30 The Sacred Council feels great joy in the fruitful zealous collaboration of the Eastern and the Western Catholic Churches and at the same time declares: All these directives of law are laid down in view of the present situation until such time as the Catholic Church and the separated Eastern Churches come together into complete unity. Meanwhile, however, all Christians, Eastern as well as Western, are earnestly asked to pray to God fervently and assiduously, nay, indeed daily, that, with the aid of the most holy Mother of God, all may become one. Let them pray also that the strength and the consolation of the Holy Spirit may descend copiously upon all those many Christians of whatsoever church they be who endure suffering and deprivations for their unwavering avowal of the name of Christ. "Love one another with fraternal charity, anticipating one another with honor" (Rom.12:10). Each and all these matters which are set forth in this decree have been favorably voted on by the Fathers of the Council. And we, by the apostolic authority given us by Christ and in union with the Fathers, approve, decree and establish them in the Holy Spirit and command that they be promulgated for the glory of God. Given in Rome at St. Peter's, November 21, 1964
