The Faith
Not a list of rules but a person, and the truth about him. The faith is set out here in order, with the questions that stand in the way answered plainly.
The Apostles’ Creed
I believe in God, the Father almighty, Creator of heaven and earth.
I believe in Jesus Christ, his only Son, our Lord, who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died and was buried; he descended into hell; on the third day he rose again from the dead; he ascended into heaven, and is seated at the right hand of God the Father almighty; from there he will come to judge the living and the dead.
I believe in the Holy Spirit, the holy catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and life everlasting. Amen.
Every person is made for God, and nothing less will hold us.
We are the only creatures who ask why we exist. We hunger for a beauty no beauty satisfies, a truth no answer closes, a love no love keeps. The Church reads that hunger as a memory: we were made by God and for God, and the restlessness of the human heart is the residue of that belonging. “You have made us for yourself, O Lord, and our heart is restless until it rests in you” (Augustine, Confessions I.1).
Catholic faith is not a decision to stop thinking. It is the mind consenting to what God has shown, on the strength of evidence: a universe that begins, a fine-tuning no accident explains, a moral law written on the conscience, and above all a tomb that was found empty and a company of frightened men who died insisting they had seen the risen Lord. Faith completes reason; it does not replace it (Catechism, 154–159).
A God who forced his own evidence on us would leave no room for love, only for compliance. He gives enough light to make faith reasonable and enough darkness to make it free. That is the shape of every love worth the name.
The Trinity is not a complication of the faith. It is the faith.
The Father is God, the Son is God, the Holy Spirit is God; the Father is not the Son, nor the Son the Spirit, nor the Spirit the Father. One divine nature, shared whole and undivided by three real Persons, distinguished only by how they stand to one another: the Father unbegotten, the Son eternally begotten, the Spirit eternally breathed forth. The word “Trinity” is not in the Bible; the thing itself is everywhere in it (Matthew 28:19; John 1:1–3; 2 Corinthians 13:14).
The Church did not choose the hardest words for the fun of it. Every simpler answer was tried and found to break something: that Christ is a creature breaks worship; that the Father suffered on the cross breaks the Father; that the Spirit is a force breaks Pentecost. Nicaea and Chalcedon are not inventions but fences built around the words of Scripture so that nothing revealed is lost.
What Catholics profess each Sunday is the faith of the apostles, put in order by the councils of the Church and unchanged since. It is given whole below, and it is short enough to learn by heart.
The Bible is the Church’s book, and the Church is the Bible’s household.
For nearly four centuries there was no book called the Bible — there were scrolls and letters read aloud in the assembly. The Church, guided by the Spirit she was promised, discerned which writings were apostolic and read them at Mass, and only then gathered them into a canon. The list of the twenty-seven New Testament books is a decision of the Church, made in councils at Hippo, Carthage and Rome. To accept the books is to accept the household that recognised them.
Revelation reaches us as one stream in two channels: the written word and the living handing-on of it — the liturgy, the Fathers, the councils, the creed, the practice of prayer. “Stand firm and hold to the traditions you were taught by us, either by word of mouth or by letter” (2 Thessalonians 2:15). Scripture is the highest part of that tradition, and never stands alone.
The Bible has been misread into a hundred contrary doctrines by readers with a hundred contrary starting points. The Catholic reads Scripture within the faith that produced it: in the liturgy, with the Fathers, under the creed, alert to the four senses — literal, allegorical, moral and anagogical — and never against the rule of faith. “No prophecy of Scripture is a matter of one’s own interpretation” (2 Peter 1:20).
God does not only tell us he loves us. He touches us.
A sacrament is an outward and visible sign of an inward and invisible grace, instituted by Christ, by which grace is actually given. Not a memory of something that happened, and not a badge of something already true, but an act of God in the present moment. Water is not a poem about washing; it washes.
Baptism, which buries us with Christ and raises us to new life; Confirmation, which seals the gift of the Spirit for witness; the Eucharist, the body and blood of the Lord; Penance, where sins are forgiven by the ministry of the Church; Anointing of the Sick, the healing of the whole person; Holy Orders, the consecration of bishops, priests and deacons; and Matrimony, the covenant of a man and a woman made a sign of Christ and the Church.
The sacraments act ex opere operato — from the work done, not from the worthiness of the one doing it or receiving it. That is why a Catholic can be at peace with a priest they would not choose as a friend: the grace is Christ’s, and he does not ration it by the sanctity of his ministers. It is also why the sacraments do not work like magic: they bear fruit in the measure that the receiver does not put an obstacle in the way.
At Mass, Calvary is not repeated. It is made present.
Christ died once and his death cannot be undone or repeated (Hebrews 9:26–28). The Mass does not add to the cross; it is the same single sacrifice made present, unbloodily, on the altar — the same Victim and the same Priest, the eternal Son, through the ministry of an ordained man. That is why the Church can call the Mass a sacrifice without implying that Jesus suffers again.
The bread and wine become the body and blood, soul and divinity, of the risen Christ: not a symbol of him, not a spiritual presence alongside the bread, but a change of the whole substance, while the appearances of bread and wine remain. He said it too plainly to be a metaphor — “my flesh is true food” — and the people who heard him left over it (John 6:55, 66). The earliest Christians believed the same, and were accused of cannibalism for it by their pagan neighbours.
The Mass is not a performance watched by an audience. It is an act of the whole assembled Church, in which the people answer, sing, offer and receive. The responses printed in red in the Order of Mass are not decoration: they are the part the body of Christ says with her Lord, and the Second Vatican Council asked that the faithful take them up again in voice.
The Church on earth is not the whole Church.
The Council of Ephesus in 431 gave her the title that guards the truth about her Son: Theotokos, God-bearer. If Jesus is one Person, truly God and truly man, then the one born of her is God, and she who bore him is the Mother of God. Her four Catholic dogmas — divine motherhood, perpetual virginity, immaculate conception, assumption — are four fences around the incarnation, each one protecting some aspect of who her Son is.
We ask the saints to pray for us exactly as we ask a friend on earth, and for the same reason: their prayers are better than ours (James 5:16). Those who stand before the throne are not dead; they are more alive than we are, and the prayers of the saints rise with incense before the Lamb (Revelation 5:8; 8:3–4). To ask their intercession is not to worship them: worship belongs to God alone, and the Church forbids it to anyone else under the first commandment.
Death does not sever the body of Christ, it only divides it into its parts: the pilgrim Church on earth, the suffering Church being purified, and the glorious Church in heaven — one Church in three states, praying for one another. That is what the Creed means when it says “I believe in the communion of saints”.
Christ built a household, and put a steward in charge of it.
“You are Peter, and on this rock I will build my Church, and the gates of hell shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven” (Matthew 16:18–19). The name, the rock, the keys and the binding are all given to one man, and to no other apostle in that way.
His hearers knew the phrase. In Isaiah 22 the king takes the key of the house of David from a steward and gives it to another, with the words “he shall be a father to the inhabitants of Jerusalem”. It is a promise of an office, an office that continues after the man who holds it dies. So it is with Peter: an office in the Lord’s household, whose holder can be replaced, and whose keys pass on.
The first Christians were told by their own historians who led the Church in Rome: Peter, then Linus, Ananias, Clement. The line has never been broken. When a pope teaches the whole Church on faith and morals ex cathedra, the promise of Matthew 16 holds: the Spirit keeps the office from teaching error, though he does not keep its holders from personal sin — and the Church has never pretended otherwise.
Because a book cannot settle a quarrel about what it means, and a company of equals has no last word. The papacy is the sacrament of unity in a visible Church: one household, one steward, one faith — so that the world may believe that the Father sent the Son (John 17:21).
The Church is a hospital, not a court of the virtuous.
Sin is real, and it wounds the sinner, the Church and the world. But no sin is greater than the mercy that has already been offered for it. The Church says out loud the thing no other body dares: that there is nothing a person has done that cannot be forgiven if they will have it. That is why confession exists — so that a word with authority can be said over a truly sorry heart, and a person can hear their sin unbound.
Hell is not a punishment God enjoys inflicting. It is the state of a will fixed forever in refusal, and the Church insists it is possible precisely because she insists that freedom is real. She has never said of any named person that they are in it. She has canonised thousands and declared none of the rest.
We profess the resurrection of the body — not escape from the flesh but its healing. At the end of history the Lord will come in glory, judge the living and the dead, and make all things new. What God has promised is not a life after death so much as a world made right, in which every tear is wiped away, and the dwelling of God is with men (Revelation 21:1–5).
Apologetics
An answer that hides the difficulty is no answer at all. These are the objections most often raised, and the reasons the Church has given for two thousand years.
