"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). The Catholic faith is deeply rooted in the Bible. Here are the scriptural foundations for some commonly questioned Catholic beliefs.
Sacred Tradition
The Bible itself affirms that not everything was written down and that we must hold fast to oral tradition.
"So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter."
— 2 Thessalonians 2:15
The Authority of the Pope
Jesus established a visible Church with Peter as its head.
"And I tell you, you are Peter, and on this rock I will build my church, and the powers of death 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, and whatever you loose on earth shall be loosed in heaven."
— Matthew 16:18-19
Faith and Works
We are saved by grace, but true faith works through love.
"You see that a man is justified by works and not by faith alone... For as the body apart from the spirit is dead, so faith apart from works is dead."
— James 2:24, 26
Infant Baptism
Baptism replaces circumcision as the sign of the covenant, and in the New Testament, entire households were baptized.
"And he took them the same hour of the night, and washed their wounds, and he was baptized at once, with all his family."
— Acts 16:33
The Real Presence in the Eucharist
Catholics believe that the Eucharist is truly the Body and Blood of Christ, not just a symbol.
"Jesus said to them, '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 food indeed, and my blood is drink indeed.'"
— John 6:53-55
At the Last Supper, he said, "This is my body" and "This is my blood," not "This represents my body" (Matthew 26:26-28).
Confession to a Priest
Jesus gave his Apostles the authority to forgive sins.
"Jesus said to them again, 'Peace be with you. As the Father has sent me, even so I send you.' And when he had said this, he breathed on them, and said to them, '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
Mary, Mother of God
Mary is honored because of her unique role in salvation history.
"Hail, full of grace, the Lord is with you!"
— Luke 1:28
"For behold, henceforth all generations will call me blessed."
— Luke 1:48
Jesus gave Mary to us as our mother from the Cross: "Behold, your mother!" (John 19:27).
The Intercession of Saints
Catholics ask the saints in heaven to pray for them, just as we ask fellow Christians on earth for prayers.
"And when he had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp, and with golden bowls full of incense, which are the prayers of the saints."
— Revelation 5:8
Purgatory
Scripture indicates a state of purification for those who die in God's friendship but are still imperfectly purified.
"It is therefore a holy and wholesome thought to pray for the dead, that they may be loosed from sins."
— 2 Maccabees 12:46
"If any man's work is burned up, he will suffer loss, though he himself will be saved, but only as through fire."
— 1 Corinthians 3:15
