THE SACRAMENT OF THE EUCHARIST

1322 The holy Eucharist completes Christian initiation. Those who have been raised to the dignity of the royal priesthood by Baptism and configured more deeply to Christ by Confirmation participate with the whole community in the Lord’s own sacrifice by means of the Eucharist.

1323 “At the Last Supper, on the night he was betrayed, our Savior instituted the Eucharistic sacrifice of his Body and Blood. This he did in order to perpetuate the sacrifice of the cross throughout the ages until he should come again, and so to entrust to his beloved Spouse, the Church, a memorial of his death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet ‘in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us.'”¹³³

1. The Eucharist – Source and Summit of Ecclesial Life

1324 The Eucharist is “the source and summit of the Christian life.”¹³⁴ “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.”¹³⁵

1325 “The Eucharist is the efficacious sign and sublime cause of that communion in the divine life and that unity of the People of God by which the Church is kept in being. It is the culmination both of God’s action sanctifying the world in Christ and of the worship men offer to Christ and through him to the Father in the Holy Spirit.”¹³⁶

1326 Finally, by the Eucharistic celebration we already unite ourselves with the heavenly liturgy and anticipate eternal life, when God will be all in all.¹³⁷

1327 In brief, the Eucharist is the sum and summary of our faith: “Our way of thinking is attuned to the Eucharist, and the Eucharist in turn confirms our way of thinking.”¹³⁸

Fr. Bob Writes: The Trinity—From the Catechism of the Catholic Church-

1. “IN THE NAME OF THE FATHER AND OF THE SON AND OF THE HOLY SPIRIT”…………

232 Christians are baptized “in the name of the Father and of the Son and of the Holy Spirit”⁵³ Before receiving the sacrament, they respond to a three-part question when asked to confess the Father, the Son and the Spirit: “I do.” “The faith of all Christians rests on the Trinity.”⁵⁴

233 Christians are baptized in the name of the Father and of the Son and of the Holy Spirit: not in their names,⁵⁵ for there is only one God, the almighty Father, his only Son and the Holy Spirit: the Most Holy Trinity.

234 The mystery of the Most Holy Trinity is the central mystery of Christian faith and life. It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them. It is the most fundamental and essential teaching in the “hierarchy of the truths of faith”.⁵⁶ The whole history of salvation is identical with the history of the way and the means by which the one true God, Father, Son and Holy Spirit, reveals himself to men “and reconciles and unites with himself those who turn away from sin”.⁵⁷

235 This paragraph expounds briefly (I) how the mystery of the Blessed Trinity was revealed, (II) how the Church has articulated the doctrine of the faith regarding this mystery, and (III) how, by the divine missions of the Son and the Holy Spirit, God the Father fulfils the “plan of his loving goodness” of creation, redemption and sanctification.

236 The Fathers of the Church distinguish between theology (theologia) and economy (oikonomia). “Theology” refers to the mystery of God’s inmost life within the Blessed Trinity and “economy” to all the works by which God reveals himself and communicates his life. Through the oikonomia the theologia is revealed to us; but conversely, the theologia illuminates the whole oikonomia. God’s works reveal who he is in himself; the mystery of his inmost being enlightens our understanding of all his works. So it is, analogously, among human persons. A person dis-closes himself in his actions, and the better we know a person, the better we understand his actions.

237 The Trinity is a mystery of faith in the strict sense, one of the “mysteries that are hidden in God, which can never be known unless they are revealed by God”.⁵⁸ To be sure, God has left traces of his Trinitarian being in his work of creation and in his Revelation throughout the Old Testament. But his inmost Being as Holy Trinity is a mystery that is inaccessible to reason alone or even to Israel’s faith before the Incarnation of God’s Son and the sending of the Holy Spirit.
