CATECHISM OF THE CATHOLIC CHURCH APOSTOLIC CONSTITUTION / FIDEI DEPOSITUM

The divinity and Humanity of Jesus Christ

The unique and altogether singular event of the Incarnation of the Son of God does not mean that Jesus Christ is part God and part man, nor does it imply that he is the result of a confused mixture of the divine and the human. He became truly man while remaining truly God. Jesus Christ is true God and true man. During the first centuries, the Church had to defend and clarify this truth of faith against the heresies that falsified it. CCC 464

The first heresies denied not so much Christ's divinity as his true humanity (Gnostic Docetism). From apostolic times the Christian faith has insisted on the true incarnation of God's Son "come in the flesh."87 But already in the third century, the Church in a council at Antioch had to affirm against Paul of Samosata that Jesus Christ is Son of God by nature and not by adoption. The first ecumenical council of Nicaea in 325 confessed in its Creed that the Son of God is "begotten, not made, of the same substance (homoousios) as the Father," and condemned Arius, who had affirmed that the Son of God "came to be from things that were not" and that he was "from another substance" than that of the Father.88 CCC

After the Council of Chalcedon, some made of Christ's human nature a kind of personal subject. Against them, the fifth ecumenical council at Constantinople in 553 confessed that "there is but one hypostasis [or person], which is our Lord Jesus Christ, one of the Trinity."93 Thus everything in Christ's human nature is to be attributed to his divine person as its proper subject, not only his miracles but also his sufferings and even his death: "He who was crucified in the flesh, our Lord Jesus Christ, is true God, Lord of glory, and one of the Holy Trinity."94 CCC

Key Points At the time appointed by God, the only Son of the Father, the eternal Word, that is, the Word and substantial Image of the Father, became incarnate; without losing his divine nature he has assumed human nature.

Key Points Jesus Christ is true God and true man, in the unity of his divine person; for this reason he is the one and only mediator between God and men.

Key Points Jesus Christ possesses two natures, one divine and the other human, not confused, but united in the one person of God's Son.

Key Points Christ, being true God and true man, has a human intellect and will, perfectly attuned and subject to his divine intellect and divine will, which he has in common with the Father and the Holy Spirit. The Incarnation is therefore the mystery of the wonderful union of the divine and human natures in the one person of the Word.

The death and Resurrection of Jesus Christ

Key Points By the expression "He descended into hell," the Apostles' Creed confesses that Jesus did really die and through his death for us conquered death and the devil "who has the power of death" (Heb 2:14). In his human soul united to his divine person, the dead Christ went down to the realm of the dead. He opened heaven's gates for the just who had gone before him.

I. The Historical and Transcendent Event The mystery of Christ's resurrection is a real event, with manifestations that were historically verified, as the New Testament bears witness. In about A.D. 56, St. Paul could already write to the Corinthians: "I delivered to you as of first importance what I also received, that Christ died for our sins in accordance with the scriptures, and that he was buried, that he was raised on the third day in accordance with the scriptures, and that he appeared to Cephas, then to the Twelve..."491 Apostle speaks here of the living tradition of the Resurrection which he had learned after his conversion at the gates of Damascus

Key Points Faith in the Resurrection has as its object an event which is historically attested to by the disciples, who really encountered the Risen One. At the same time, this event is mysteriously transcendent insofar as it is the entry of Christ's humanity into the glory of God. The empty tomb and the linen cloths lying there signify in themselves that by God's power Christ's body had escaped the bonds of death and corruption. They prepared the disciples to encounter the Risen Lord. Christ, "the first-born from the dead" (Col 1:18), is the principle of our own resurrection, even now by the justification of our souls (cf. Rom 6:4), and one day by the new life he will impart to our bodies (cf. Rom 8:11).

The Nature of God and the Trinity

Key Points The mystery of the Most Holy Trinity is the central mystery of the Christian faith and of Christian life. God alone can make it known to us by revealing himself as Father, Son, and Holy Spirit. The Incarnation of God's Son reveals that God is the eternal Father and that the Son is consubstantial with the Father, which means that, in the Father and with the Father, the Son is one and the same God. The mission of the Holy Spirit, sent by the Father in the name of the Son (Jn 14:26) and by the Son "from the Father" (Jn 15:26), reveals that, with them, the Spirit is one and the same God. "With the Father and the Son he is worshipped and glorified" (Nicene Creed).

Key Points "The Holy Spirit proceeds from the Father as the first principle and, by the eternal gift of this to the Son, from the communion of both the Father and the Son" (St. Augustine, De Trin. 15, 26, 47: PL 42:1095). By the grace of Baptism "in the name of the Father and of the Son and of the Holy Spirit," we are called to share in the life of the Blessed Trinity, here on earth in the obscurity of faith, and after death in eternal light (Cf. Paul VI, CPG § 9).

Key Points "Now this is the Catholic faith: We worship one God in the Trinity and the Trinity in unity, without either confusing the persons or dividing the substance; for the person of the Father is one, the Son's is another, the Holy Spirit's another; but the Godhead of the Father, Son, and Holy Spirit is one, their glory equal, their majesty coeternal" (Athanasian Creed; DS 75; ND 16). Inseparable in what they are, the divine persons are also inseparable in what they do. But within the single divine operation each shows forth what is proper to him in the Trinity, especially in the divine missions of the Son's Incarnation and the gift of the Holy Spirit.

Revelation

Key Points By love, God has revealed himself and given himself to man. He has thus provided the definitive, superabundant answer to the questions that man asks himself about the meaning and purpose of his life. God has revealed himself to man by gradually communicating his own mystery in deeds and in words.

Key Points Beyond the witness to himself that God gives in created things, he manifested himself to our first parents, spoke to them and, after the fall, promised them salvation (cf. Gen 3:15) and offered them his covenant. God made an everlasting covenant with Noah and with all living beings (cf. Gen 9:16). It will remain in force as long as the world lasts.

Key Points God chose Abraham and made a covenant with him and his descendants. By the covenant God formed his people and revealed his law to them through Moses. Through the prophets, he prepared them to accept the salvation destined for all humanity. God has revealed himself fully by sending his own Son, in whom he has established his covenant for ever. The Son is his Father's definitive Word; so there will be no further Revelation after him.

Salvation

Salvation comes from God alone; but because we receive the life of faith through the Church, she is our mother: "We believe the Church as the mother of our new birth, and not in the Church as if she were the author of our salvation."55 Because she is our mother, she is also our teacher in the faith.55 Faith is necessary for salvation. The Lord himself affirms: "He who believes and is baptized will be saved; but he who does not believe will be condemned"
