The Eucharist, the Source and Summit of the Christian Life
"The Church draws her life from the Eucharist. This truth does not simply express a daily experience of faith, but recapitulates the heart of the mystery of the Church....
The Second Vatican Council rightly proclaimed that the Eucharistic sacrifice is 'The source and summit of the Christian life.' 'For the most holy Eucharist contains the Church's entire spiritual wealth: Christ himself, our Passover and living bread. Through his own flesh, now made living and life-giving by the Holy Spirit, he offers life to men.' Consequently the gaze of the Church is constantly turned to her Lord, present in the Sacrament of the Altar, in which she discovers the full manifestation of his boundless love."
-St. John Paul II (Ecclesia de Eucharistia, Holy Thursday, April 17, 2003)
