The Eucharist is “the source and summit of the Christian life.” “The other sacraments, and indeed all ecclesiastical ministries and works of the apostolate, are bound up with the Eucharist and are oriented toward it. For in the blessed Eucharist is contained the whole spiritual good of the Church, namely Christ himself, our Pasch.” (Catechism of the Catholic Church, 1324).

In The Story of a Soul, St. Therese of Lisieux describes her First Communion by saying that she and Jesus had been “gazing” at each other for a long time, and it was a deep joy to finally be one, in the Eucharist.

"By the sacred anointing of the sick and the prayer of the priests, the whole Church commends those who are ill to the suffering and glorified Lord, that he may raise them up and save them. And indeed she exhorts them to contribute to the good of the People of God by freely uniting themselves to the Passion and death of Christ." (Catechism of the Catholic Church, para. 1499)
