Ut Unum Sint §45

⁴⁵ Corresponding to the liturgical renewal carried out by the Catholic Church, certain other Ecclesial Communities have made efforts to renew their worship. Some, on the basis of a recommendation expressed at the ecumenical level, have abandoned the custom of celebrating their liturgy of the Lord's Supper only infrequently and have opted for a celebration each Sunday. Again, when the cycles of liturgical readings used by the various Christian Communities in the West are compared, they appear to be essentially the same. Still on the ecumenical level, very special prominence has been given to the liturgy and liturgical signs (images, icons, vestments, light, incense, gestures). Moreover, in schools of theology where future ministers are trained, courses in the history and significance of the liturgy are beginning to be part of the curriculum in response to a newly discovered need. These are signs of convergence which regard various aspects of the sacramental life. Certainly, due to disagreements in matters of faith, it is not yet possible to celebrate together the same Eucharistic Liturgy. And yet we do have a burning desire to join in celebrating the one Eucharist of the Lord, and this desire itself is already a common prayer of praise, a single supplication. Together we speak to the Father and increasingly we do so "with one heart". At times it seems that we are closer to being able finally to seal this "real although not yet full" communion. A century ago who could even have imagined such a thing?
