Our fraternal encounter today is a new and necessary step on the journey towards the unity to which only the Holy Spirit can lead us, that of communion in legitimate diversity. We call to mind with profound gratitude the steps that the Lord has already enabled us to undertake. The embrace exchanged between Pope Paul VI and Patriarch Athenagoras here in Jerusalem, after many centuries of silence, paved the way for a momentous gesture, the removal from the memory and from the midst of the Church of the acts of mutual excommunication in 1054. This was followed by an exchange of visits between the respective Sees of Rome and Constantinople, by regular correspondence and, later, by the decision announced by Pope John Paul II and Patriarch Dimitrios, of blessed memory both, to initiate a theological dialogue of truth between Catholics and Orthodox. Over these years, God, the source of all peace and love, has taught us to regard one another as members of the same Christian family, under one Lord and Saviour, Jesus Christ, and to love one another, so that we may confess our faith in the same Gospel of Christ, as received by the Apostles and expressed and transmitted to us by the Ecumenical Councils and the Church Fathers. While fully aware of not having reached the goal of full communion, today we confirm our commitment to continue walking together towards the unity for which Christ our Lord prayed to the Father so "that all may be one" (Jn 17:21).
