Evangelii Nuntiandi §12

12. But Christ also carries out this proclamation by innumerable signs, which amaze the crowds and at the same time draw them to Him in order to see Him, listen to Him and allow themselves to be transformed by Him: the sick are cured, water is changed into wine, bread is multiplied, the dead come back to life. And among all these signs there is the one to which He attaches great importance: the humble and the poor are evangelized, become His disciples and gather together "in His name" in the great community of those who believe in Him. For this Jesus who declared, "I must preach the Good News of the Kingdom of God"[29] is the same Jesus of whom John the Evangelist said that He had come and was to die "to gather together in unity the scattered children of God."[30] Thus He accomplishes His revelation, completing it and confirming it by the entire revelation that He makes of Himself, by words and deeds, by signs and miracles, and more especially by His death, by His resurrection and by the sending of the Spirit of Truth.[31]
