Jesus Christ is the incarnate Son of God and the redeemer of the human race.

DEUS CARITAS EST—BENEDICT XVI
INTRODUCTION

1. “God is love, and he who abides in love abides in God, and God abides in him” (1 Jn 4:16). These words from the First Letter of John express with remarkable clarity the heart of the Christian faith: the Christian image of God and the resulting image of mankind and its destiny. In the same verse, Saint John also offers a kind of summary of the Christian life: “We have come to know and to believe in the love God has for us”.

We have come to believe in God's love: in these words the Christian can express the fundamental decision of his life. Being Christian is not the result of an ethical choice or a lofty idea, but the encounter with an event, a person, which gives life a new horizon and a decisive direction. Saint John's Gospel describes that event in these words: “God so loved the world that he gave his only Son, that whoever believes in him should ... have eternal life” (3:16). In acknowledging the centrality of love, Christian faith has retained the core of Israel's faith, while at the same time giving it new depth and breadth. The pious Jew prayed daily the words of the Book of Deuteronomy which expressed the heart of his existence: “Hear, O Israel: the Lord our God is one Lord, and you shall love the Lord your God with all your heart, and with all your soul and with all your might” (6:4-5). Jesus united into a single precept this commandment of love for God and the commandment of love for neighbor found in the Book of Leviticus: “You shall love your neighbor as yourself” (19:18; cf. Mk 12:29-31). Since God has first loved us (cf. 1 Jn 4:10), love is now no longer a mere “command”; it is the response to the gift of love with which God draws near to us.

In a world where the name of God is sometimes associated with vengeance or even a duty of hatred and violence, this message is both timely and significant. For this reason, I wish in my first Encyclical to speak of the love which God lavishes upon us and which we in turn must share with others. That, in essence, is what the two main parts of this Letter are about, and they are profoundly interconnected. The first part is more speculative, since I wanted here—at the beginning of my Pontificate—to clarify some essential facts concerning the love which God mysteriously and gratuitously offers to man, together with the intrinsic link between that Love and the reality of human love. The second part is more concrete, since it treats the ecclesial exercise of the commandment of love of neighbor. The argument has vast implications, but a lengthy treatment would go beyond the scope of the present Encyclical. I wish to emphasize some basic elements; so as to call forth in the world renewed energy and commitment in the human response to God's love.

The Parents are THE MOST IMPORTANT catechists. It is the Parent who first passes on, and consistently reinforces, the Faith. Parents are the principal models of Catholicism. 

As a result, with their parents leading the way by example and family Prayer, children and indeed everyone gathered around the family hearth will find a readier path to human maturity, salvation and holiness. Graced with the dignity and office of fatherhood and motherhood, parents will energetically acquit themselves of a duty which devolves primarily on them, namely education and especially religious education.

Initiation, the ecclesial community and the family
19. It should be kept in mind that the whole of Christian initiation is a process of conversion undertaken with God's help and with constant reference to the ecclesial community, both when an adult is seeking entry into the Church, as happens in places of first evangelization and in many secularized regions, and when parents request the sacraments for their children. In this regard, I would like to call particular attention to the relationship between Christian initiation and the family. In pastoral work it is always important to make Christian families part of the process of initiation. Receiving Baptism, Confirmation and First Holy Communion are key moments not only for the individual receiving them but also for the entire family, which should be supported in its educational role by the various elements of the ecclesial community. (53) Here I would emphasize the importance of First Holy Communion. For many of the faithful, this day continues to be memorable as the moment when, even if in a rudimentary way, they first came to understand the importance of a personal encounter with Jesus. Parish pastoral programs should make the most of this highly significant moment.

To be alive and fully present at Mass is the essential catechesis because the Eucharist is the Source and summit of our Faith.

To participate in the mass is: to be attentive to the Reading from Scripture, Responding to the prayers, and proper disposed (being in a state of Grace) for the reception of the Eucharist. This is what we are all striving to achieve, because the Mass is heaven on Earth.

10. Nevertheless the liturgy is the summit toward which the activity of the Church is directed; at the same time it is the font from which all her power flows. For the aim and object of apostolic works is that all who are made sons of God by faith and baptism should come together to praise God in the midst of His Church, to take part in the sacrifice, and to eat the Lord's supper SACROSANCTUM CONCILIUM (CONSTITUTION ON THE SACRED LITURGY) Second Vatican Council

From the Catechism of the Catholic Church

1324 The Eucharist is "the source and summit of the Christian life."136 "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."137

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."138

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.139

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."140
