The Catholic faith is built upon the revelation of God to humanity, entrusted to the Church. It is not a collection of opinions, but a coherent body of truth that illuminates the meaning of our existence.
Scripture and Tradition
Divine Revelation is transmitted through two distinct but closely connected modes: Sacred Scripture (the Bible) and Sacred Tradition. Together, they form a single deposit of faith. The Magisterium—the teaching office of the Church—serves this deposit by authentically interpreting the Word of God.
The Most Holy Trinity
We believe in one God who is eternally three distinct persons: the Father, the Son, and the Holy Spirit. This is the central mystery of the Christian faith (see CCC 232-267). The Trinity is a communion of love, and we are created in the image of this love.
Original Sin
Through the disobedience of our first parents, Adam and Eve, sin entered the world, and with it, death and suffering. Every human being (except Mary, by a singular grace) inherits this fallen state called original sin—not a personal fault, but a deprivation of original holiness and justice. Baptism washes away original sin and restores the life of grace, though its effects (concupiscence, suffering, and death) remain. See CCC 396-421.
Jesus Christ
We believe that Jesus Christ is the Son of God, the Second Person of the Trinity, who became man to save us from sin and death. He is fully God and fully man (see CCC 464-483). Through his life, passion, death, and resurrection, he opened the gates of heaven and reconciled humanity with God.
The Church
We believe that the Catholic Church is the Body of Christ on earth, established by Jesus himself (see CCC 751-776). It is "one, holy, catholic, and apostolic." Through the Church, Christ continues his saving work, dispensing grace and teaching the truth with authority.
Salvation and Grace
We believe that we are saved by grace through faith and works (see CCC 1987-2029). Salvation is a free gift from God, but we must cooperate with that gift through our choices and actions. The goal of our life is beatitude: eternal happiness with God in heaven.
The Real Presence in the Eucharist
Catholics believe that in the Eucharist, the bread and wine truly become the Body, Blood, Soul, and Divinity of Jesus Christ. This change is called transubstantiation. The Eucharist is not a mere symbol; it is Christ himself, substantially present under the appearances of bread and wine. Jesus declared: "This is my body" and "This is my blood" (see CCC 1373-1381). The Eucharist is "the source and summit of the Christian life" (Lumen Gentium, 11).
The Blessed Virgin Mary
Mary holds a unique place in the Catholic faith as the Mother of God (Theotokos). She was conceived without original sin (the Immaculate Conception), consented freely to become the mother of the Savior, remained a virgin, and was assumed body and soul into heaven at the end of her earthly life. Catholics do not worship Mary; we honor her as the greatest of all the saints and ask for her powerful intercession. "All generations will call me blessed" (Luke 1:48). See CCC 484-511.
The Communion of Saints
The Church is not limited to those currently living on earth. It includes the saints in heaven and the souls in purgatory. We are all united in the Body of Christ. We ask the saints, and especially Mary, the Mother of God, to pray for us, just as we ask our friends on earth to pray for us.
The Moral Law
God has inscribed a natural moral law in the human heart, and he revealed it definitively in the Ten Commandments and the teaching of Christ. The two Great Commandments summarize the whole law: love God with all your heart, soul, and mind, and love your neighbor as yourself (Matthew 22:37-40). The Church teaches that there are acts which are intrinsically evil and can never be justified, regardless of circumstances or intentions. The moral life is not a burden but a response of love to the God who first loved us. See CCC 1949-1986.
The Ten Commandments and the Beatitudes
Catholic moral life is shaped by both the Ten Commandments and the Beatitudes. The Commandments teach us what must never be chosen against God and neighbor, while the Beatitudes reveal the inner dispositions of a disciple: poverty of spirit, mercy, purity of heart, hunger for righteousness, and perseverance in persecution.
Conscience, Sin, and Conversion
Conscience is not a private invention of right and wrong; it must be formed in truth through Scripture, prayer, sound teaching, and wise counsel. The Church distinguishes mortal sin, which destroys charity in the heart, from venial sin, which wounds it. Catholics are also called to avoid near occasions of sin and to practice regular examination of conscience, so that repentance is concrete and growth in holiness is steady.
Virtues and Vices
Grace heals and elevates human nature by forming virtue. The theological virtues are faith, hope, and charity; the cardinal virtues are prudence, justice, fortitude, and temperance. The moral struggle also includes resisting vice, including pride, greed, lust, envy, gluttony, wrath, and sloth, by relying on prayer, sacramental grace, and concrete habits of self-denial.
The Precepts of the Church
The Precepts of the Church are the minimum level of commitment required of the faithful (see CCC 2041-2043).
- You shall attend Mass on Sundays and on holy days of obligation and rest from servile labor.
- You shall confess your sins at least once a year.
- You shall receive the sacrament of the Eucharist at least during the Easter season.
- You shall observe the days of fasting and abstinence established by the Church.
- You shall help to provide for the needs of the Church.
- You shall observe the laws of the Church concerning marriage.
The Four Last Things
The Church teaches that every human life has an eternal destiny. The "Four Last Things" are Death, Judgment, Heaven, and Hell. At the moment of death, each soul undergoes a particular judgment. Those who die in God's grace and friendship and are perfectly purified live for ever with Christ in Heaven. Those who die in God's grace, but are still imperfectly purified, are assured of their eternal salvation; but after death they undergo purification (Purgatory), so as to achieve the holiness necessary to enter the joy of heaven. Those who die in a state of mortal sin, without repentance, separate themselves from God forever (Hell).
Purgatory
Those who die in God's grace but are not yet fully purified undergo a process of purification called Purgatory, so as to achieve the holiness necessary to enter heaven. Purgatory is not a "second chance" but a mercy of God for those already assured of salvation. The Church has always prayed for the dead, and Scripture itself supports this practice: "It is a holy and wholesome thought to pray for the dead, that they may be loosed from sins" (2 Maccabees 12:46). See CCC 1030-1032.
