Catechism of the Catholic Church
Excerpts from the Catechism of the Catholic Church are included below as information for teachers. They present the Church’s teachings contained in this unit.
1101 The Holy Spirit gives a spiritual understanding of the Word of God to those who read or hear it, according to the dispositions of their hearts. By means of
the words, actions, and symbols that form the structure of a celebration, the Spirit puts both the faithful and the ministers into a living relationship with Christ, the Word and Image of the Father, so that they can live out the meaning of what they hear, contemplate, and do in the celebration.
1324 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.
1374 The mode of Christ's presence under the Eucharistic species is unique. It raises the Eucharist above all the sacraments as the perfection of the spiritual life and the end to which all the sacraments tend. In the most blessed sacrament of the Eucharist "the body and blood, together with the soul and divinity, of our Lord Jesus Christ and, therefore, the whole Christ is truly, really, and substantially contained. This presence is called 'real' - by which is not intended to exclude the other types of presence as if they could not be 'real' too, but because it is presence in the fullest sense: that is to say, it is a substantial presence by which Christ, God and man, makes himself wholly and entirely present.
1408 The Eucharistic celebration always includes: the proclamation of the Word of God; thanksgiving to God the Father for all his benefits, above all the gift of his Son; the consecration of bread and wine; and participation in the liturgical banquet by receiving the Lord's body and blood. These elements constitute one single act of worship.
1413 By the consecration the transubstantiation of the bread and wine into the Body and Blood of Christ is brought about. Under the consecrated species of bread and wine Christ himself, living and glorious, is present in a true, real, and substantial manner: his Body and his Blood, with his soul and his divinity.
