How does the Eucharist relate to other sacraments?

Answer 1

Roman Catholic AnswerBaptism is the initiation in the Christian life, it makes one a new creation: it takes away original sin and infuses a capability of being pleasing to God and of doing good works (with God's help). It allows one to participate in Christ's own life, the life of the Church, receiving the Sacraments, and growing in holiness with His grace:

from The Catechism of the Catholic Church, second edition, English translation 1994

1113 The whole liturgical life of the Church revolves around the Eucharistic sacrifice and the sacraments. (Cf. Sacrosanctum concilium 6) There are seven sacraments in the Church: Baptism, Confirmation or Chrismation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony. (Cf. Council of Lyons II (1274) Denzinger-Schonmetzer, Enchiridion Symbolorum, definitionum et declarationum de rebus fidei et morum (1965) ...

1212 The sacraments of Christian initiation - Baptism, Confirmation, and the Eucharist - lay the foundations of every Christian life. "The sharing in the divine nature given to men through the grace of Christ bears a certain likeness to the origin, development, and nourishing of natural life. The faithful are born anew by Baptism, strengthened by the sacrament of Confirmation and receive in the Eucharist the food of eternal life. By means of these sacraments of Christian initiation, they thus receive in increasing measure the treasures of the divine life and advance toward the perfection of charity." (Paul VI, apostolic constitution, Divinae consortium naturae: AAS 63 (1971) 657; cf. RCIA Introduction 1-2.

1213 This sacrament is called Baptism, after the central rite by which it is carried out: to baptize (Greek baptizein means to "plunge" or "immerse"; the "plunge" into the water symbolizes the catechumen's burial into Christ's death, from which he rises up by resurrection with him, as "a new creature." (2 Cor 5:17; Gal 6:15; cf Rom6:3-4, Col 2:12)

1269 Having become a member of the Church, the person baptized belongs no longer to himself, but to him who died and rose for us. (Cf. 1 Cor 6:19; 2 Cor 5:15.) From now on, he is called to be subject to others, to serve them in the communion of the Church, and to "obey and submit" to the Church's leaders, (Heb 13:17.) Holding them in respect and affection. (Cf. Eph 5:21; 1 Cor 16:15-16; 1 Thess 5:12-13; Jn 13:12-15.) Just as Baptism is the source of responsibilities and duties, the baptized person also enjoys rights within the Church: to receive the sacraments, to be nourished with the Word of God and to be sustained by the other spiritual helps of the Church. (Cf. Lumen Gentium 37; Codex Iuris Canonici, cann. 208-223; Corpus Canonum Ecclesiarum Orientalium, can. 675:2.)
