Sit Down First

Questions people ask about Catholicism

Twenty questions as people type them, each with the passage to read first and a one-line answer from each side.

How to read these

Each question starts with the passage to read, linked to where it is quoted in context. Then one line from each side, in its own words, with a link to where it comes from. The Protestant line is mostly from GotQuestions, the largest Protestant answer site, which leans Baptist and evangelical; where Lutherans, Anglicans or Presbyterians would answer differently, the line says so.

20 questions

Are Catholics Christians?

Scripture: John 17:20-23, read in context under what each side says about the other.

The Catholic answer

Yes. The Catechism says the one Church of Christ “subsists in” the Catholic Church, and calls Protestants brothers. Catechism 816 and 818

The Protestant answer

Divided. GotQuestions says “It depends.” on the person’s trust in Christ; Gavin Ortlund answers “My answer to that is yes.” GotQuestions

Do Catholics worship Mary?

Scripture: Mark 3:31-35, read in context under praying to Mary.

The Catholic answer

No. Devotion to Mary “differs essentially from the adoration which is given to the incarnate Word”. Catechism 971

The Protestant answer

Agreed in principle, “The Bible is clear that we are to worship God alone”, but GotQuestions holds that Catholic practice crosses the line. GotQuestions

Why do Catholics pray to saints?

Scripture: 1 Timothy 2:1-6, read in context under asking the saints to pray.

The Catholic answer

Because the saints in heaven pray for us: “They do not cease to intercede with the Father for us”. Catechism 956

The Protestant answer

“Praying to Mary and other saints is unbiblical.” Lutherans grant that the saints pray for the Church but still do not pray to them. GotQuestions

Why do Catholics confess to a priest?

Scripture: John 20:19-23, read in context under the passage it turns on.

The Catholic answer

Because Christ gave his ministers authority to forgive: “If you forgive the sins of any, they are forgiven.” Catholic Answers, Confession

The Protestant answer

“The concept of confession of sin to a priest is nowhere taught in Scripture.” Lutherans and Anglicans keep private confession and absolution as an option. GotQuestions

Do Catholics believe you are saved by works?

Scripture: Romans 4:1-8, read in context under Paul on faith apart from works.

The Catholic answer

No. Trent says “we are therefore said to be justified freely”, and in 1999 the Church signed that we are accepted “not because of any merit on our part”. Council of Trent, Session 6

The Protestant answer

Protestants hold that salvation is by faith alone and read Trent’s canons as adding works to faith as the ground of standing with God. GotQuestions

Is the pope infallible in everything?

Scripture: John 16:12-15, read in context under can the pope teach without error.

The Catholic answer

No. “Only what he solemnly defines is considered to be infallible teaching”, and infallibility does not mean sinless. Catholic Answers, Papal Infallibility

The Protestant answer

GotQuestions holds that the office itself “is not scriptural”, so the question of its infallibility does not arise. GotQuestions

Why does the Catholic Bible have 73 books?

Scripture: Acts 17:10-12, read in context under which books.

The Catholic answer

Because the seven disputed Old Testament books “had been regarded as canonical since the beginning of Church history”. Catholic Answers, The Old Testament Canon

The Protestant answer

The count is right: “46 in the Old Testament and 27 in the New Testament”. Protestants hold the seven were never in the Hebrew canon Jesus used. GotQuestions

Can Catholics read the Bible?

Scripture: 2 Timothy 3:14-17, read in context under the passage it turns on.

The Catholic answer

Yes, and they are urged to: “Easy access to Sacred Scripture should be provided for all the Christian faithful”. Vatican II, Dei Verbum 22

The Protestant answer

The Protestant point is authority, not access: Scripture alone is the final rule, and no church may bind what Scripture does not. GotQuestions

Do Catholics worship statues?

Scripture: Exodus 20:1-6, read in context under the passage it turns on.

The Catholic answer

No. “God forbade the worship of statues, but he did not forbid the religious use of statues.” Catholic Answers, Do Catholics Worship Statues?

The Protestant answer

GotQuestions says yes, “a form of idolatry”; Lutherans and Anglicans allow images and refuse to bow to them; the Reformed allow neither in worship. GotQuestions

Why can’t priests marry?

Scripture: 1 Corinthians 7:32-35, read in context under is the rule wise.

The Catholic answer

A rule, not a doctrine: “priestly celibacy is not an unchangeable dogma but a disciplinary rule”. Eastern Catholic priests may be married. Catholic Answers, Celibacy and the Priesthood

The Protestant answer

“the Bible encourages, but does not demand celibacy of priests / church leaders.” GotQuestions

What is purgatory?

Scripture: 1 Corinthians 3:10-15, read in context under the passage it turns on.

The Catholic answer

A final cleansing of the saved: “purification, so as to achieve the holiness necessary to enter the joy of heaven”. Catechism 1030

The Protestant answer

“The Bible says nothing about purgatory.” Christ’s work leaves nothing to be purged. GotQuestions

Do Catholics believe in being born again?

Scripture: 1 Peter 3:18-22, read in context under does baptism save.

The Catholic answer

Yes, in baptism: “Since all Catholics have been baptized, all Catholics have been born again.” Catholic Answers, Are Catholics Born Again?

The Protestant answer

“Baptism is not what gives us salvation.” New birth comes through faith; Lutherans and Anglicans tie it to baptism more closely than Baptists do. GotQuestions

Why do Catholics baptise babies?

Scripture: Acts 16:29-34, read in context under baptising babies.

The Catholic answer

“The practice of infant Baptism is an immemorial tradition of the Church.” Catechism 1252

The Protestant answer

Baptists say “The Bible is silent on infant baptism”; Lutherans, Anglicans, Presbyterians and Methodists baptise infants as Catholics do. GotQuestions

Is the Mass a re-sacrifice of Jesus?

Scripture: Hebrews 10:10-18, read in context under is the Mass a sacrifice.

The Catholic answer

No new death: “The sacrifice of Christ and the sacrifice of the Eucharist are one single sacrifice”; the Mass “re-presents (makes present)” the cross. Catechism 1366 and 1367

The Protestant answer

GotQuestions calls it a “re-sacrifice” and answers with Hebrews: “He sacrificed for their sins once for all when He offered Himself.” GotQuestions

Can a Protestant take Catholic communion?

Scripture: 1 Corinthians 10:16-17, read in context under one bread, one body.

The Catholic answer

Ordinarily no: members of churches “not yet fully united are ordinarily not admitted to Holy Communion”. Exceptions need the bishop. US bishops, guidelines for receiving communion

The Protestant answer

Agreed on the fact, since Protestants do not hold transubstantiation; most Protestant churches welcome any baptised believer to their own table. GotQuestions on transubstantiation

Why do Catholics call priests “Father” when Matthew 23:9 says not to?

Scripture: Matthew 23:1-12, read in context under call no man father.

The Catholic answer

Jesus is not forbidding the word for those who are fathers, in the family or in the faith; Paul calls himself the Corinthians’ father. Catholic Answers, Call No Man Father

The Protestant answer

GotQuestions partly agrees: the saying is “an exhortation to humility”, not a ban on a word. GotQuestions

Why do Catholics worship on Sunday and not the Sabbath?

Scripture: Romans 14:5-6, in context

One man esteems one day as more important. Another esteems every day alike. Let each man be fully assured in his own mind. He who observes the day, observes it to the Lord; and he who does not observe the day, to the Lord he does not observe it. He who eats, eats to the Lord, for he gives God thanks. He who doesn’t eat, to the Lord he doesn’t eat, and gives God thanks.

Romans 14:5-6In context. Paul to the Roman church on disputes between the weak and the strong: one keeps a day as special and another does not; each should be convinced and do it for the Lord.

The Catholic answer

Because “the first Christians understood this principle and gathered for worship on Sunday”, the day of the resurrection. Catholic Answers, Sabbath or Sunday?

The Protestant answer

Most Protestants worship on Sunday too; GotQuestions holds that Sabbath-keeping is not required of Christians on either day. GotQuestions

Do Catholics believe non-Catholics go to hell?

Scripture: John 17:20-23, read in context under what each side says about the other.

The Catholic answer

No blanket claim: those who “through no fault of their own, do not know the Gospel of Christ” can be saved, and separated Christians are not charged with the separation. Catechism 847 and 818

The Protestant answer

GotQuestions notes the old formula “has been softened to a degree” and holds that salvation is in Christ, not in any church. GotQuestions

Did the Catholic Church add books to the Bible?

Scripture: Acts 17:10-12, read in context under which books.

The Catholic answer

No, the Reformers set books aside “even though these books had been regarded as canonical since the beginning of Church history”. Catholic Answers, The Old Testament Canon

The Protestant answer

Protestants say the seven were never in the Hebrew Bible and are not Scripture, though many read them: the Church of England reads them “for example of life and instruction of manners; but yet doth it not apply them to establish any doctrine”. Thirty-nine Articles, Article 6

Did the Catholic Church change the Ten Commandments?

Scripture: Deuteronomy 5:6-10, read in context under did the Church change the Ten Commandments.

The Catholic answer

No, it numbers them differently: “The division and numbering of the Commandments have varied in the course of history”, following Augustine. Lutherans number them the same way. Catechism 2066

The Protestant answer

GotQuestions confirms there are still ten, “the tenth commandment is then split in two”; the dispute is over images, which the Orthodox and most Protestants count as a commandment of their own. GotQuestions
