112 It is a source of joy and hope to Us, Venerable Brethren, to note the spiritual fervor that is being aroused in this varied and wide circle of Christians. For this would seem to augur well for the future unification of all Christians in the one Church of Christ. We pray for the breath of the Holy Spirit on the ecumenical movement, and recall once more the emotion and joy We felt in Jerusalem at our meeting with the Patriarch Athenagoras. It was a meeting that abounded in charity, and fired Us with new hope. We welcome with gratitude and respect those representatives of the separated churches who are taking part in the Second Vatican Ecumenical Council. We assure them once again of Our enthusiastic and attentive interest in all those spiritual movements concerned or connected with the problem of unity which are stirring individuals, groups, and communities noted for their noble piety. We greet all these Christians with love and reverence, confident that the cause of Christ and the unity which He Himself willed for His Church will be promoted by our sincere and friendly dialogue.
