1. I Believe in God the Father

The symbols of faith are composite formulas, also called “professions of faith” or “Creeds”, with which the Church from her very beginning has set forth synthetically and handed on her own faith in a language that is normative and common to all the faithful.

The most ancient symbols of faith are the baptismal creeds. Because Baptism is conferred “in the name of the Father, and of the Son, and of the Holy Spirit” (Matthew 28:19), the truths of faith professed at Baptism are articulated in reference to the three Persons of the Most Holy Trinity.

They are the Apostles' Creed which is the ancient baptismal symbol of the Church of Rome and the Nicene-Constantinopolitan Creed which stems from the first two ecumenical Councils, that of Nicea (325 A.D.) and that of Constantinople (381 A.D.) and which even to this day are common to all the great Churches of the East and the West.

The Profession of Faith begins with these words because the affirmation “I believe in God” is the most important, the source of all the other truths about man and about the world, and about the entire life of everyone who believes in God.

Belief in the one God is professed because he has revealed himself to the people of Israel as the only One when he said, “Hear, O Israel, the Lord our God is one Lord” (Deuteronomy 6:4) and “there is no other” (Isaiah 45:22). Jesus himself confirmed that God is “the one Lord” (Mark 12:29). To confess that Jesus and the Holy Spirit are also God and Lord does not introduce any division into the one God.

God revealed himself to Moses as the living God, “the God of Abraham, the God of Isaac, the God of Jacob” (Exodus 3:6). God also revealed to Moses his mysterious name “I Am Who I Am (YHWH)”. Already in Old Testament times this ineffable name of God was replaced by the divine title Lord. Thus in the New Testament, Jesus who was called Lord is seen as true God.

Since creatures have received everything they are and have from God, only God in himself is the fullness of being and of every perfection. God is “He who is” without origin and without end. Jesus also reveals that he bears the divine name “I Am” (John 8:28).

In revealing his name, God makes known the riches contained in the ineffable mystery of his being. He alone is from everlasting to everlasting. He is the One who transcends the world and history. It is he who made heaven and earth. He is the faithful God, always close to his people, in order to save them. He is the highest holiness, “rich in mercy” (Ephesians 2:4), always ready to forgive. He is the One who is spiritual, transcendent, omnipotent, eternal, personal, and perfect. He is truth and love.

“God is the infinitely perfect being who is the most Holy Trinity.”

God is Truth itself and as such he can neither deceive nor be deceived. He is “light, and in him there is no darkness” (1 John 1:5). The eternal Son of God, the incarnation of wisdom, was sent into the world “to bear witness to the Truth” (John 18:37).

God revealed himself to Israel as the One who has a stronger love than that of parents for their children or of husbands and wives for their spouses. God in himself “is love” (1 John 4: 8.16), who gives himself completely and gratuitously, who “so loved the world that he gave his only Son so that the world might be saved through him” (John 3:16-17). By sending his Son and the Holy Spirit, God reveals that he himself is an eternal exchange of love.

To believe in the one and only God involves coming to know his greatness and majesty. It involves living in thanksgiving and trusting always in him, even in adversity. It involves knowing the unity and true dignity of all human beings, created in his image. It involves making good use of the things which he has created.

The central mystery of Christian faith and life is the mystery of the Most Blessed Trinity. Christians are baptized in the name of the Father and of the Son and of the Holy Spirit.

God has left some traces of his trinitarian being in creation and in the Old Testament but his inmost being as the Holy Trinity is a mystery which is inaccessible to reason alone or even to Israel’s faith before the Incarnation of the Son of God and the sending of the Holy Spirit. This mystery was revealed by Jesus Christ and it is the source of all the other mysteries.

Jesus Christ revealed to us that God is “Father”, not only insofar as he created the universe and the mankind, but above all because he eternally generated in his bosom the Son who is his Word, “ the radiance of the glory of God and the very stamp of his nature” (Hebrews 1:3).

The Holy Spirit is the third Person of the Most Blessed Trinity. He is God, one and equal with the Father and the Son. He “proceeds from the Father” (John 15:26) who is the principle without a principle and the origin of all trinitarian life. He proceeds also from the Son (Filioque) by the eternal Gift which the Father makes of him to the Son. Sent by the Father and the Incarnate Son, the Holy Spirit guides the Church “to know all truth” (John 16:13).

The Church expresses her trinitarian faith by professing a belief in the oneness of God in whom there are three Persons: Father, Son, and Holy Spirit. The three divine Persons are only one God because each of them equally possesses the fullness of the one and indivisible divine nature. They are really distinct from each other by reason of the relations which place them in correspondence to each other. The Father generates the Son; the Son is generated by the Father; the Holy Spirit proceeds from the Father and the Son.

Inseparable in their one substance, the three divine Persons are also inseparable in their activity. The Trinity has one operation, sole and the same. In this one divine action, however, each Person is present according to the mode which is proper to him in the Trinity.

“O my God, Trinity whom I adore...grant my soul peace; make it your heaven, your beloved dwelling, and the place of your rest. May I never abandon you there, but may I be there, whole and entire, completely vigilant in my faith, entirely adoring, and wholly given over to your creative action.”

God reveals himself as “the strong One, the mighty One” (Psalm 24:8), as the One “to whom nothing is impossible” (Luke 1:37). His omnipotence is universal, mysterious and shows itself in the creation of the world out of nothing and humanity out of love; but above all it shows itself in the Incarnation and the Resurrection of his Son, in the gift of filial adoption and in the forgiveness of sins. For this reason, the Church directs her prayers to the “almighty and eternal God” (“Omnipotens sempiterne Deus...”).

The significance is that creation is the foundation of all God’s saving plans. It shows forth the almighty and wise love of God, and it is the first step toward the covenant of the one God with his people. It is the beginning of the history of salvation which culminates in Christ; and it is the first answer to our fundamental questions regarding our very origin and destiny.

The Father, the Son, and the Holy Spirit are the one and indivisible principle of creation even though the work of creating the world is particularly attributed to God the Father.

The world was created for the glory of God who wished to show forth and communicate his goodness, truth and beauty. The ultimate end of creation is that God, in Christ, might be “all in all” (1 Corinthians 15:28) for his glory and for our happiness.

“The glory of God is man fully alive; moreover man’s life is the vision of God.”

God created the universe freely with wisdom and love. The world is not the result of any necessity, nor of blind fate, nor of chance. God created “out of nothing” (ex nihilo) (2 Maccabees 7:28) a world which is ordered and good and which he infinitely transcends. God preserves his creation in being and sustains it, giving it the capacity to act and leading it toward its fulfillment through his Son and the Holy Spirit.

Divine Providence consists in the dispositions with which God leads his creatures toward their ultimate end. God is the sovereign Master of his own plan. To carry it out, however, he also makes use of the cooperation of his creatures. For God grants his creatures the dignity of acting on their own and of being causes for each other.

While respecting our freedom, God asks us to cooperate with him and gives us the ability to do so through actions, prayers and sufferings, thus awakening in us the desire “to will and to work for his good pleasure” (Philippians 2:13).

To this question, as painful and mysterious as it is, only the whole of Christian faith can constitute a response. God is not in any way - directly or indirectly - the cause of evil. He illuminates the mystery of evil in his Son Jesus Christ who died and rose in order to vanquish that great moral evil, human sin, which is at the root of all other evils.

Faith gives us the certainty that God would not permit evil if he did not cause a good to come from that very evil. This was realized in a wondrous way by God in the death and resurrection of Christ. In fact, from the greatest of all moral evils (the murder of his Son) he has brought forth the greatest of all goods (the glorification of Christ and our redemption).

Sacred Scripture says, “In the beginning, God created the heavens and the earth” (Genesis 1:1). The Church in her profession of faith proclaims that God is the Creator of everything, visible and invisible, of all spiritual and corporeal beings, that is, of angels and of the visible world and, in a special way, of man.

The angels are purely spiritual creatures, incorporeal, invisible, immortal, and personal beings endowed with intelligence and will. They ceaselessly contemplate God face-to-face and they glorify him. They serve him and are his messengers in the accomplishment of his saving mission to all.

The Church joins with the angels in adoring God, invokes their assistance and commemorates some in her liturgy.

“ Beside each believer stands an angel as a protector and shepherd leading him to life.”

Through the account of the “six days” of creation Sacred Scripture teaches us the value of the created world and its purpose, namely, to praise God and to serve humanity. Every single thing owes its very existence to God from whom it receives its goodness and perfection, its proper laws and its proper place in the universe.

The human person is the summit of visible creation in as much as he or she is created in the image and likeness of God.

There exist an interdependence and a hierarchy among creatures as willed by God. At the same time, there is also a unity and solidarity among creatures since all have the same Creator, are loved by him and are ordered to his glory. Respecting the laws inscribed in creation and the relations which derive from the nature of things is, therefore, a principle of wisdom and a foundation for morality.

The work of creation culminates in the still greater work of redemption, which in fact gives rise to a new creation in which everything will recover its true meaning and fulfillment.

The human person is created in the image of God in the sense that he or she is capable of knowing and of loving their Creator in freedom. Human beings are the only creatures on earth that God has willed for their own sake and has called to share, through knowledge and love, in his own divine life. All human beings, in as much as they are created in the image of God, have the dignity of a person. A person is not something but someone, capable of self-knowledge and of freely giving himself and entering into communion with God and with other persons.

God has created everything for them; but he has created them to know, serve and love God, to offer all of creation in this world in thanksgiving back to him and to be raised up to life with him in heaven. Only in the mystery of the incarnate Word does the mystery of the human person come into true light. Man and woman are predestined to reproduce the image of the Son of God made Man, who is the perfect “image of the invisible God” (Colossians 1:15).

All people form the unity of the human race by reason of the common origin which they have from God. God has made “from one ancestor all the nations of men” (Acts 17:26). All have but one Savior and are called to share in the eternal happiness of God.

The human person is a being at once corporeal and spiritual. In man spirit and matter form one nature. This unity is so profound that, thanks to the spiritual principle which is the soul, the body which is material, becomes a living human body and participates in the dignity of the image of God.

The spiritual soul does not come from one’s parents but is created immediately by God and is immortal. It does not perish at the moment when it is separated from the body in death and it will be once again reunited with the body at the moment of the final resurrection.

Man and woman have been created by God in equal dignity insofar as they are human persons. At the same time, they have been created in a reciprocal complementarity insofar as they are masculine and feminine. God has willed them one for the other to form a communion of persons. They are also called to transmit human life by forming in matrimony “one flesh” (Genesis 2:24). They are likewise called to subdue the earth as “stewards” of God.

In creating man and woman God had given them a special participation in his own divine life in holiness and justice. In the plan of God they would not have had to suffer or die. Furthermore, a perfect harmony held sway within the human person, a harmony between creature and Creator, between man and woman, as well as between the first human couple and all of creation.

Sin is present in human history. This reality of sin can be understood clearly only in the light of divine revelation and above all in the light of Christ the Savior of all. Where sin abounded, he made grace to abound all the more.

This expression indicates that Satan and the other demons, about which Sacred Scripture and the Tradition of the Church speak, were angels, created good by God. They were, however, transformed into evil because with a free and irrevocable choice they rejected God and his Kingdom, thus giving rise to the existence of hell. They try to associate human beings with their revolt against God. However, God has wrought in Christ a sure victory over the Evil One.

When tempted by the devil, the first man and woman allowed trust in their Creator to die in their hearts. In their disobedience they wished to become “like God” but without God and not in accordance with God (Genesis 3:5). Thus, Adam and Eve immediately lost for themselves and for all their descendants the original grace of holiness and justice.

Original sin, in which all human beings are born, is the state of deprivation of original holiness and justice. It is a sin “contracted” by us not “committed”; it is a state of birth and not a personal act. Because of the original unity of all human beings, it is transmitted to the descendants of Adam “not by imitation, but by propagation”. This transmission remains a mystery which we cannot fully understand.

In consequence of original sin human nature, without being totally corrupted, is wounded in its natural powers. It is subject to ignorance, to suffering, and to the dominion of death and is inclined toward sin. This inclination is called concupiscence.

After the first sin the world was inundated with sin but God did not abandon man to the power of death. Rather, he foretold in a mysterious way in the “Protoevangelium” (Genesis 3:15) that evil would be conquered and that man would be lifted up from his fall. This was the first proclamation of the Messiah and Redeemer. Therefore, the fall would be called in the future a “happy fault” because it “gained for us so great a Redeemer” (Liturgy of the Easter Vigil).
