Apologetics

The Hard Questions

Every honest question deserves an honest, charitable answer. Here are the objections to the Catholic faith we hear most — each met from Scripture and the Catechism, never to win an argument, but to share the truth with love.

“Always be prepared to make a defense to anyone who calls you to account for the hope that is in you, yet do it with gentleness and reverence.”
1 Peter 3:15–16

Question 1

Why do Catholics pray to Mary and the saints?

“Doesn’t the Bible say there is one mediator between God and man?”

“First of all, then, I urge that supplications, prayers, intercessions… be made for all… For there is one God, and there is one mediator between God and men, the man Christ Jesus.”

1 Timothy 2:1, 5

Catholics worship God alone. We do not worship Mary or the saints — we ask them to pray for us, exactly as you might ask a friend to pray for you. The same Scripture that calls Christ the one mediator urges us, in the very same breath, to intercede for one another. Death does not break the bonds of love in Christ: those in heaven are more alive in Him than we are, and Scripture shows them offering our prayers before God (Revelation 5:8). Mary herself prophesied that “all generations will call me blessed” (Luke 1:48), and at her word Christ worked His first miracle (John 2:1–11). To ask her prayers is not to rival Christ but to lean, with the whole family of God, on His one mediation.

CCC §956, §2673–2679

Question 2

Why confess sins to a priest instead of directly to God?

“Why can’t I just tell God I’m sorry?”

“As the Father has sent me, even so I send you.”… “Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.”

John 20:21–23

We do tell God we are sorry — but Christ also gave a tangible gift. On Easter night He breathed on the Apostles and gave them His own authority to forgive sins in His name. For that authority to be exercised, sins must be spoken aloud and heard. The priest is not a substitute for God; he is the instrument through whom Christ Himself absolves, and through whom we receive the certainty of being forgiven — words we can actually hear. Scripture commands us to “confess your sins to one another” (James 5:16) and calls this the “ministry of reconciliation” entrusted to the Church (2 Corinthians 5:18–20).

CCC §1441–1442, §1461

Question 3

Why do Catholics follow the Pope?

“Where is the papacy in the Bible?”

“You are Peter, and on this rock I will build my church… 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

Christ singled out one Apostle, renamed him “Rock,” and handed him the keys — an image of stewardship over the household of God (Isaiah 22:22). He prayed that Peter’s faith would not fail so he could strengthen the others (Luke 22:31–32), and after the Resurrection commissioned him three times to “feed my sheep” (John 21:15–17). The Pope, as Peter’s successor, is the visible source and foundation of the Church’s unity — not a king above the Gospel, but a servant of the servants of God, charged with keeping the flock one and faithful across every age.

CCC §880–882, §891

Question 4

Why do Catholics believe the Eucharist is truly Christ?

“Isn’t the bread just a symbol of Jesus?”

“Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you… For my flesh is true food, and my blood is true drink.”

John 6:53–55

When His listeners recoiled at these words, Jesus did not soften them or explain them away as a metaphor — He repeated them more forcefully, and many disciples left (John 6:60–66). At the Last Supper He said plainly, “This is my body… this is my blood” (Luke 22:19–20). St. Paul warns that whoever receives unworthily “profanes the body and blood of the Lord” (1 Corinthians 11:27) — language no one uses about a mere symbol. The Church believes what Christ said: the appearances of bread and wine remain, but the reality becomes His own Body and Blood, soul and divinity. We call this transubstantiation. It is the source and summit of the Christian life.

CCC §1374, §1376, §1413

Question 5

Why does the Catholic Bible have more books?

“Did the Catholic Church add books to Scripture?”

“Therefore he made atonement for the dead, that they might be delivered from their sin.”

2 Maccabees 12:46

The Church did not add books — they were there from the beginning. The first Christians used the Septuagint, the Greek Old Testament, which included the seven books in question (Tobit, Judith, Wisdom, Sirach, Baruch, and 1–2 Maccabees, with parts of Esther and Daniel). These were read as Scripture for over fifteen centuries; the canon was formally listed by the Church in the fourth century. It was the Protestant reformers in the 1500s who removed them. So the question is not why Catholics added books, but why they were later taken away. The Catholic Bible preserves the canon the Church has always received.
