«We rejoice with you, dear friends, at the renewal of the spiritual life manifested in the Church today, in different forms and in various environments. [...] In all that, we can recognize the mysterious and hidden work of the Spirit, who is the soul of the church.»

Address of Paul VI on  occasion of the first International Leaders' Conference, Grottaferrata (Rome) 10 October 1973

«How then could this "spiritual renewal" not be "a chance" for the church and for the world? And how, in this case, could one not take all the means to ensure that it remains so? [...] Nothing is more necessary for such a world, more and more secularized, than the testimony of this "spiritual renewal", which we see the Holy Spirit bring about today in the most diverse regions and environments. Its manifestations are varied: deep communion of souls, close contact with God in faithfulness to the commitments undertaken at Baptism, in prayer that is often community prayer, in which each one, expressing himself freely, helps, supports and nourishes the prayer of others, and, at the basis of everything, a personal conviction. This conviction has its source not only in instruction received by faith but also in a certain experience of real life, namely, that without God, man can do nothing, that with him, on the contrary, everything becomes possible.»
