Together we can rejoice in the fact that the [ecumenical] dialogue, with the passage of time, has brought about a renewed sense of our brotherhood and has created a more open and trusting climate between Christians belonging to the various churches and ecclesial communities. My venerable predecessor, in his encyclical
Ut Unum Sint (1995), saw this as an especially significant fruit of dialogue (cf. nn. 41ff.; 64).
I feel the fact that we consider one another brothers and sisters, that we love one another, that together we are witnesses of Jesus Christ, should not be taken so much for granted. I believe that this brotherhood is in itself a very important fruit of dialogue that we must rejoice in, continue to foster and to practice (
