What the Catholic Church teaches — in plain language, with sources, in depth.
The Profession of Faith
What Catholics believe about God, Christ, and the Holy Spirit. The twelve articles of the Creed explained.
The Father, the Son, and the Holy Spirit are three distinct Persons sharing one divine nature -- one God, not three.
Jesus of Nazareth was crucified, died, and was buried. On the third day he rose bodily from the dead. The resurrection is a historical event with real witnesses, not a myth or a metaphor.
The bishops of the Catholic Church stand in an unbroken line of succession from the apostles, who received their authority directly from Christ.
Christ gave Peter a unique authority among the apostles, and that authority has been transmitted to Peter's successors, the bishops of Rome.
Through Adam's sin, all human beings inherit a wounded nature deprived of original holiness and justice. This inherited condition is called original sin.
The Church is a communion of all the faithful -- those on earth, the souls in purgatory, and the saints in heaven. Death does not sever the bonds of the Body of Christ.
Mary is the Mother of God (Theotokos) because she is the mother of Jesus, who is God incarnate. The Church also honors her as ever-virgin, immaculately conceived, and assumed into heaven.
Those who die in God's grace but are not yet fully purified undergo a process of purification after death before entering heaven.
The Celebration of the Christian Mystery
The seven sacraments, the liturgy, and how the Church prays. What each sacrament does and why it matters.
The seven sacraments are visible signs instituted by Christ that confer the grace they signify. They are not mere symbols; they actually accomplish what they represent.
The bread and wine become the body and blood of Christ -- truly, really, and substantially.
Christ gave his apostles the power to forgive sins in his name. Catholic confession is the ordinary way this power is exercised in the Church today.
The Christian Moral Life
The Ten Commandments, moral theology, natural law, and the virtue tradition. What Catholic ethics actually says.
God's grace initiates, accompanies, and completes salvation. Human free will cooperates with grace but cannot earn it. Grace and freedom are not in competition; they work together.
Salvation is entirely the gift of God's grace, received through faith, but genuine faith necessarily produces good works. Faith and works are not opposed; they are two aspects of one reality.
Hell is the state of definitive self-exclusion from communion with God. It is real, eternal, and freely chosen by those who persist in mortal sin without repentance.
Salvation is offered to all through Christ. Those who know the Catholic Church is necessary for salvation and refuse to enter or remain in it cannot be saved. Those who are invincibly ignorant of the Gospel may be saved through grace working in ways known to God.
