Slavorum Apostoli §27

²⁷ Cyril and Methodius are as it were the connecting links or spiritual bridge between the Eastern and Western traditions, which both come together in the one great Tradition of the universal Church. For us they are the champions and also the patrons of the ecumenical endeavor of the sister Churches of East and West, for the rediscovery through prayer and dialogue of visible Unity in perfect and total communion, "the unity which", as I said on the occasion of my visit to Bari, "is neither absorption nor fusion". Unity is a meeting in truth and love, granted to us by the Spirit. Cyril and Methodius, in their personality and their work, are figures that awaken in all Christians a great "longing for union" and for unity between the two sister Churches of East and West. For full catholicity, every nation, every culture has its own part to play in the universal plan of salvation. Every particular tradition, every local Church must remain open and alert to the other Churches and traditions and, at the same time, to universal and catholic communion; were it to remain closed in on itself, it too would run the risk of becoming impoverished. By exercising their own charism, Cyril and Methodius made a decisive contribution to the building of Europe not only in Christian religious communion but also to its civil and cultural union. Not even today does there exist any other way of overcoming tensions and repairing the divisions and antagonisms both in Europe: and in the world which threaten to cause a frightful destruction of lives and values. Being Christians in our day means being builders of communion in the Church and in society. This calls for openness to others, mutual understanding, and readiness to cooperate through the generous exchange of cultural and spiritual resources. One of the fundamental aspirations of humanity today is to rediscover unity and communion for a life truly worthy of man on the worldwide level. The Church, conscious of being the universal sign and sacrament of salvation and of the unity of the human race, declares her readiness to accomplish this duty of hers, to which "the conditions of this age lend special urgency so that all people joined more closely today by various social, technical, and cultural bonds can achieve as well full unity in Christ".
