1. Why should I believe in God?
Because reason, creation, and human experience all point to a Creator. The Church teaches that belief in God is not blind—it is both reasonable and supported by Revelation.
“The existence of God the Creator can be known with certainty through His works, by the light of human reason.” — Catechism of the Catholic Church (CCC) §286
The beauty, order, and intelligibility of the universe suggest a rational Creator. Human longing for truth, love, and purpose hints at something beyond the material.
“If you have seen something beautiful, know that it came from God.” — St. Augustine, Confessions
2. Why should I believe humans are fallen and need salvation?
Catholic Answer:
Because the human condition—suffering, sin, death, and moral failure—is evidence of something broken. The Church calls this Original Sin, a rupture in humanity’s relationship with God that we cannot fix by ourselves.
“All men are implicated in Adam's sin.” — CCC §402
“For all have sinned and fall short of the glory of God.” — Romans 3:23
We need salvation not just because we do wrong, but because we are wounded at the root.
“Man, having been created free, by his own fault fell under the power of the devil.” — St. Irenaeus, Against Heresies, Book 3
3. Why should I believe in and trust the Bible? Why is it the Word of God, and not other scriptures like the Koran or Vedas?
Catholic Answer:
The Bible is the Word of God because it is divinely inspired, historically rooted, and confirmed by the life, death, and Resurrection of Christ. Unlike the Qur’an or the Vedas, the Bible was written over centuries, by many authors, yet maintains a consistent message of salvation that culminates in Christ.
“Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit.” — CCC §81
Jesus confirmed the authority of the Old Testament and fulfilled it. His followers, the Apostles, wrote the New Testament under the inspiration of the Holy Spirit, and the early Church discerned which writings were authentic.
“We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us.” — St. Irenaeus, Against Heresies, Book 3

4. Why should I believe in Jesus Christ?
Catholic Answer:
Because no one else claimed to be God, backed it up with miracles, died for our sins, and rose from the dead.
“Jesus is the only Son of God, begotten, not made, consubstantial with the Father.” — Nicene Creed
“I am the Way, the Truth, and the Life. No one comes to the Father except through Me.” — John 14:6
“He became what we are, that He might make us what He is.” — St. Athanasius, On the Incarnation
He is not one teacher among many. He is God incarnate, who entered history and conquered death.
Q: What does the Catholic Church teach about Jesus?
A: Jesus is the eternal Son of God, fully divine and fully human. He is the second Person of the Trinity, who became man for our salvation.
“In the beginning was the Word... and the Word was God.” — John 1:1
“The Word became flesh and dwelt among us.” — John 1:14
“Jesus Christ is true God and true man.” — CCC §464
“He was made man that we might be made God.” — St. Athanasius, On the Incarnation
5. How can I obtain salvation?
Catholic Answer:
By God’s grace, through faith in Jesus Christ, and by cooperating with that grace through the sacraments, especially Baptism, the Eucharist, and Reconciliation.
“He who believes and is baptized will be saved.” — Mark 16:16
“Work out your salvation with fear and trembling.” — Philippians 2:12
“Faith without works is dead.” — James 2:26
“The Lord, who created you without you, will not save you without you.” — St. Augustine
Salvation is a gift, but we must respond with faith, repentance, and obedience.

The Catholic Church & The Gospel: Keeping it Simple but True
Doesn’t the Catholic Church teach that we earn our salvation through good works?
A: No. The Catholic Church teaches that salvation begins and ends with God’s grace. We cannot earn heaven by our own efforts. But we must respond freely to God’s grace through faith, love, and obedience.
“By grace you have been saved through faith, and this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.” — Ephesians 2:8–9
“God's free initiative demands man's free response.” — Catechism of the Catholic Church (CCC) §2002
Q: So what role do good works play in salvation?
A: Good works are the fruit of a living faith. They are not a way to earn God’s love—but the natural result of receiving His love. Scripture is clear: faith that doesn’t express itself in love is dead.
“Faith without works is dead.” — James 2:26
“We are His workmanship, created in Christ Jesus for good works, which God prepared in advance, that we should walk in them.” — Ephesians 2:10
“In every circumstance, each one of us should grow in holiness by a sincere faith and the practice of good works.” — St. Clement of Rome, Letter to the Corinthians, Ch. 33 (c. 96 A.D.)
Q: Does the Church believe we earn God’s grace?
A: Absolutely not. Grace is a free gift. Nothing we do can earn it. But we must cooperate with it.
“Since the initiative belongs to God in the order of grace, no one can merit the initial grace of forgiveness and justification.” — CCC §2010
“He who created you without you, will not save you without you.” — St. Augustine, Sermon 169
Q: How does this fit with being “justified by faith”?
A: Catholics believe we are initially justified by grace through faith (Romans 5:1), and that we are called to continue in that grace by living faithfully.
“For in Christ Jesus neither circumcision nor uncircumcision counts for anything, but only faith working through love.” — Galatians 5:6
“Justification establishes cooperation between God’s grace and man’s freedom.” — CCC §1993
Salvation is not “faith or works,” but faith that works—a living faith that responds to God with love.
Q: What did the Early Church teach about this?
A: The Church Fathers consistently taught that while grace comes first, we must respond with lives of obedience and charity.
“Let us be doers of His will and not merely hearers, lest we be condemned.” — St. Ignatius of Antioch, Letter to the Magnesians, Ch. 15 (c. 107 A.D.)
“A man is justified by his works and not by faith alone. What use is it to say you believe, if you do not do what is commanded?” — St. Justin Martyr, Dialogue with Trypho, Ch. 140 (c. 160 A.D.)
✅ In Summary:
Salvation is by grace alone
Faith is necessary to receive that grace
Good works are the response of a living, obedient faith
We do not earn salvation—but we must cooperate with God’s grace
“Faith by itself, if it does not have works, is dead.” — James 2:17
“If we endure, we will also reign with Him.” — 2 Timothy 2:12
6. What is “theosis” or “divinization”?
A: Theosis, or divinization, is the teaching that God makes us sharers in His divine life. It doesn’t mean we become God by nature, but that we are transformed by grace into His likeness.
“God became man so that man might become god.” — St. Athanasius, On the Incarnation, 54 (4th century)
“The Word became flesh to make us partakers of the divine nature.” — Catechism of the Catholic Church (CCC) §460
“He has granted to us His precious and very great promises, so that through them you may become partakers of the divine nature.” — 2 Peter 1:4
Theosis is the goal of salvation—to become like Christ in holiness, love, and union with the Trinity.
Q: Is this the same as becoming a god?
A: No. Theosis does not mean we become God in essence or nature. It means we are made like Him by grace—healed, elevated, and united with His divine life.
“We are called gods, not by nature, but by participation. As iron becomes fire when in the flame, so the soul is filled with God when it clings to Him.” — St. Basil the Great, On the Holy Spirit
We never become equal to God. Instead, we become adopted children, filled with His Spirit and made capable of sharing in His holiness.
“You received a spirit of adoption, by which we cry, ‘Abba, Father!’” — Romans 8:15
Q: Is theosis a Catholic teaching or just Eastern Orthodox?
A: Theosis is taught by both East and West. It is deeply rooted in Scripture and affirmed by Catholic doctrine.
“The only-begotten Son of God... assumed our nature, so that He, made man, might make men gods.” — Catechism of the Council of Trent (16th century)
“The Word became flesh... that we might become partakers of the divine nature.” — CCC §460
Council of Florence (1439 A.D.):
“The souls of the just... see the divine essence with an intuitive vision, and thus enjoy the divine nature.” — Decree for the Greeks
Q: How does theosis happen in the Christian life?
A: Theosis begins at Baptism, is nourished through the Eucharist, deepened by prayer, and advanced through a life of virtue and grace.
“It is no longer I who live, but Christ who lives in me.” — Galatians 2:20
“Be perfect as your heavenly Father is perfect.” — Matthew 5:48
“Through the sacraments... believers receive grace, and are renewed inwardly, being conformed to the likeness of God.” — St. Cyril of Jerusalem, Catechetical Lectures
Every time we say "yes" to grace, we become more like Christ—more truly ourselves, more truly alive.
Q: What role does the Eucharist play in theosis?
A: The Eucharist is the foretaste and engine of theosis. In receiving Christ’s Body and Blood, we are united to His divine life.
“He who eats my flesh and drinks my blood remains in me, and I in him.” — John 6:56
“By this sacrament we are made partakers of the divine nature. The body and blood of Christ cause us to live in Him and He in us.” — St. Thomas Aquinas, Summa Theologiae, III, q. 75, a. 1
The Eucharist is not just spiritual nourishment—it is divine union.
Q: What’s the end goal of theosis?
A: Eternal life in heaven—perfect communion with God. Not just being with Him, but being in Him, shining with His glory, filled with His love.
“When He appears, we shall be like Him, for we shall see Him as He is.” — 1 John 3:2
“In the end, God will be all in all.” — 1 Corinthians 15:28
“In heaven, we are truly divinized, seeing God face to face, becoming like Him in the beatific vision.” — CCC §1023–1024
✅ In Summary:
Theosis means becoming partakers of the divine nature
It is rooted in Scripture, affirmed by the Fathers, and taught by the Catholic Church
We are transformed by grace, not by nature
Theosis begins now and is fulfilled in heaven
“Let us become what we receive.” — St. Augustine, on the Eucharis
How can I obtain sanctification, theosis, or divinization?
Catholic Answer:
Through grace, prayer, the sacraments, and living a life of charity and union with God.
“The Word became flesh to make us partakers of the divine nature.” — CCC §460
“Be perfect, therefore, as your heavenly Father is perfect.” — Matthew 5:48
“God became man so that man might become god.” — St. Athanasius
The Church calls this sanctifying grace—the divine life in the soul that grows as we draw closer to God.
7. What is The Church?
Catholic Answer:
The Church is the Body of Christ, the People of God, and the sacrament of salvation. It is both human and divine, visible and spiritual.
“The Church is the universal sacrament of salvation.” — CCC §774
“The Church is the Body of Christ. Through the Spirit and His action in the sacraments, above all the Eucharist, Christ lives in her.” — CCC §807
“Where the Church is, there is the Spirit of God; and where the Spirit of God is, there is the Church.” — St. Irenaeus
"Wherever Jesus Christ is, there is the Catholic Church.”
— St. Ignatius of Antioch, Letter to the Smyrnaeans, Ch. 8
This is the first recorded use of the term “Catholic Church” in Christian writing. It shows that even by the early 2nd century, the Church was understood to be universal, unified, and centered on Christ.
🔹 “Let no one do anything that pertains to the Church apart from the bishop.”
— Letter to the Smyrnaeans, Ch. 8
Ignatius emphasizes the Church’s visible, hierarchical nature. Unity with the bishop (and thus with the Church) was essential for valid worship and true faith.
🔹 “Take care to do all things in harmony with God, with the bishop presiding in the place of God, and the presbyters in the place of the council of the apostles, and the deacons, who are most dear to me, entrusted with the ministry of Jesus Christ.”
— Letter to the Magnesians, Ch. 6
This passage affirms the threefold structure of Church leadership—bishop, priest (presbyter), and deacon—still present in the Catholic Church today.
🔹 “Be eager, therefore, to be firmly grounded in the teachings of the Lord and the apostles, so that you may prosper in all you do, spiritually and physically, in faith and love, in the Son and the Father and in the Spirit, in the beginning and in the end.”
— Letter to the Magnesians, Ch. 1

8. How am I saved?
Catholic Answer:
By the grace of God through faith in Jesus Christ, baptism, ongoing repentance, and a life of sacramental communion and love.
“Baptism now saves you.” — 1 Peter 3:21
“He who endures to the end will be saved.” — Matthew 24:13
“They are not saved who are not in the ark of the Church.” — St. Jerome
It’s not a one-time event—it’s a lifelong relationship with Christ through His Church.

9. Why do I need the Church to interpret Scripture? Why can't I do it myself?
Catholic Answer:
Because Scripture is not self-interpreting. The Bible was written in and for the Church, and without the Church’s Tradition, private interpretation can lead to error and division.
“No prophecy of Scripture is a matter of one’s own interpretation.” — 2 Peter 1:20
“The task of interpreting the Word of God authentically has been entrusted to the Magisterium of the Church.” — CCC §85
“We must not draw the meaning of Scripture from our own imagination, but from the tradition of the Church.” — St. Hilary of Poitiers

Scripture Came From the Church, Not the Other Way Around
Q: Why not just read the Bible for myself and follow what it says? Why do I need to trust the Church Fathers or early Christians?
A: Because the Bible was written in the Church, by the Church, and for the Church—and the Early Church Fathers are the living link between the Apostles and us today. Without them, we lose the context, continuity, and correct understanding of the faith.
🔹 1. The Church came before the Bible
The New Testament didn’t fall from the sky—it was written, preserved, and canonized by the early Church. The Gospels and epistles were written to communities already practicing the faith.
“The Church is the pillar and foundation of truth.” — 1 Timothy 3:15
“We must not merely look at what Scripture says but at what the Church has always understood it to mean.” — St. Vincent of Lérins, Commonitorium (c. 434 A.D.)
🔹 2. The Church Fathers received the Faith directly from the Apostles
The Church Fathers were not modern scholars or isolated interpreters. Many were disciples of the Apostles themselves, and they transmitted the Apostolic teaching with fidelity.
“Take care to do all things in harmony with God, with the bishop presiding in the place of God… and the presbyters in the place of the council of the apostles.” — St. Ignatius of Antioch, Letter to the Magnesians, Ch. 6 (c. 107 A.D.)
“What the apostles preached, this we have learned from their successors.” — St. Irenaeus, Against Heresies, Book 3
Their writings show us how Scripture was understood and lived in the earliest centuries—before the splintering of Christian unity.
🔹 3. Private interpretation leads to confusion and division
Without a trusted teaching authority, you end up with thousands of conflicting denominations, each claiming to follow “what the Bible says.”
“No prophecy of Scripture is a matter of one’s own interpretation.” — 2 Peter 1:20
The early Christians understood that Scripture must be read within the Church, guided by the same Spirit that inspired it.
“Separate from the Church, the Scriptures become a dead letter.” — St. Irenaeus
🔹 4. The Church Fathers are a safeguard against error
They fought heresies, defended the Trinity, upheld the divinity of Christ, and preserved the apostolic faith. Listening to them protects us from inventing a modern version of Christianity.
“He cannot have God for his Father who does not have the Church for his Mother.” — St. Cyprian of Carthage, On the Unity of the Church (c. 251 A.D.)
“Let us not seek truth in the lies of heretics, but in the traditions of the Church.” — St. Athanasius, Letter to Serapion
🔹 5. The Fathers confirm Catholic teaching
Beliefs like the Real Presence of the Eucharist, apostolic succession, baptismal regeneration, and the authority of bishops and Rome are all found in their writings. They didn’t invent new doctrines—they handed down what they had received.
✅ Conclusion: If you trust the Bible, you already trust the Church.
The same early Church that gave us the Bible also gave us sacraments, doctrine, and tradition. The Early Church Fathers didn’t distort the Gospel—they preserved it.
To read the Bible apart from them is like trying to read Shakespeare with no knowledge of English.
“In the Catholic Church, we hold that to understand Scripture rightly, we must listen to the Church that received it, lived it, and passed it on.”
10. What is the true Church?
Catholic Answer:
The one, holy, catholic, and apostolic Church founded by Christ, fully present in the Catholic Church.
“This is the one Church of Christ... which subsists in the Catholic Church.” — Lumen Gentium, §8
“Where Peter is, there is the Church.” — St. Ambrose
"Wherever Jesus Christ is, there is the Catholic Church.”
— St. Ignatius of Antioch, Letter to the Smyrnaeans, Ch. 8

This passage affirms the threefold structure of Church leadership—bishop, priest (presbyter), and deacon—still present in the Catholic Church today.
🔹 “Be eager, therefore, to be firmly grounded in the teachings of the Lord and the apostles, so that you may prosper in all you do, spiritually and physically, in faith and love, in the Son and the Father and in the Spirit, in the beginning and in the end.”
— Letter to the Magnesians, Ch. 1

11. Who established the true Church? Why?
Catholic Answer:
Jesus Christ established the Church to continue His mission of teaching, sanctifying, and governing in His name.
“You are Peter, and on this rock I will build my Church.” — Matthew 16:18
“As the Father has sent Me, I am sending you.” — John 20:21
“He who does not have the Church as his mother cannot have God as his Father.” — St. Cyprian of Carthage
The Church is not man-made—it is divinely instituted.
12. Why must I join an institution like the Catholic Church to follow Christ?
Catholic Answer:
Because Christ Himself founded the Church as the ordinary means of salvation. The Church is not a barrier to Christ—it’s His Body.
“Outside the Church there is no salvation.” — CCC §846
“He who hears you hears me.” — Luke 10:16
“We must belong to the Church Catholic to be saved.” — St. Augustine
"Wherever Jesus Christ is, there is the Catholic Church.”

To follow Christ fully is to follow Him where He is—in His Church, with the sacraments, the teaching authority, and the communion of saints. Read more here.

Why Isn’t Christianity Just a Jewish Sect?

Q: What did the early Church believe about this?
A: The earliest Christians understood themselves as the true Israel—the continuation and fulfillment of God’s promises to Abraham, through Christ.
St. Ignatius of Antioch (c. 110 A.D.):
“It is absurd to profess Christ Jesus and to Judaize. For Christianity did not believe in Judaism, but Judaism in Christianity.” — Letter to the Magnesians, ch. 10

“We are the true spiritual Israel.” — Dialogue with Trypho, ch. 11
Q: What does the Catholic Church officially teach?

“The Church is the new People of God... those who believe in Christ... are reborn, not from a perishable but from an imperishable seed.” — Catechism of the Catholic Church §782
Christianity is not a reform movement. It is the fulfillment of the Law and the Prophets, rooted in Judaism but completed in Jesus Christ. To read how Christianity went from a Jewish movement to the Catholic Church, click here:
