Catholic vs Protestant: How Each Describes Itself, Where They Meet, Where They Differ, and James 1:5 for the Question

A short passage to hold while you ask

James 1:5 comes from a letter to people facing trials, inviting them to seek wisdom honestly:

But if any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach; and it will be given to him.

It gives you permission to ask a fair question without hurry and without being reproached. You can read James 1:5 with the verses around it. A question to carry: What is the clearest question you can bring to God right now? If the question is wider than a church, what the Bible says about doubt goes further.

What they say together

The Nicene Creed confesses the Church as “one, holy, catholic and apostolic.” The Catechism, paragraph 1271 says “Baptism constitutes the foundation of communion among all Christians, including those who are not yet in full communion with the Catholic Church.” At Lund on 31 October 2016, Pope Francis and the Lutheran World Federation wrote, “We commit ourselves to further develop the communion we already share” (joint statement). Unitatis Redintegratio (1964) says “The restoration of unity among Christians is one of the main concerns of the Church” (Vatican II decree).

How the split happened, and the numbers

The word Protestant comes from 1529, when the Second Diet of Speyer heard a protest Britannica describes as “lodged in the name of freedom of conscience against the Roman Catholic majority.” Around it: 1517, Luther's Ninety-Five Theses; 1521, the Diet of Worms; 1530, the Augsburg Confession; 1534, England's Act of Supremacy; 1545 to 1563, the Council of Trent. Historians describe religious criticism, political power and printing coming together, and Catholic and Protestant historians have long stressed different causes. The Greek Orthodox Archdiocese calls 1054 the “closing act” of a separation between East and West that had begun earlier.

Pew estimated for 2010 about 1.1 billion Catholics, 800 million Protestants and 260 million Orthodox, counting Anglicans and independent churches as Protestant.

Authority and the Bible, in each body's words

Dei Verbum (1965) says “Sacred tradition and Sacred Scripture form one sacred deposit of the word of God, committed to the Church” (text), and the Catechism says the Magisterium is “not superior to the Word of God, but is its servant.” The Westminster Confession (Reformed, 1646) says Scripture's authority “dependeth not upon the testimony of any man, or church; but wholly upon God” (text). Article VI of the Thirty-Nine Articles (Anglican) says “Holy Scripture containeth all things necessary to salvation” (text), and the National Association of Evangelicals says “We believe the Bible to be the inspired, the only infallible and authoritative Word of God.”

The same passages are read differently. Catholic readings connect Matthew 16:13-19 and John 21:15-17 with Peter's pastoral office; Protestant readings commonly connect Matthew 16 with Peter's confession of Christ, and read 2 Timothy 3:14-17 as Scripture's unique sufficiency.

The Catholic canon is commonly counted as 73 books and the Protestant as 66. The difference is seven books, called deuterocanonical by Catholics and the Apocrypha in Protestant usage, plus longer forms of Esther and Daniel. Trent received them in 1546, and the Westminster Confession does not.

Sacraments, clergy and Mary

The Catechism (1210 and 1211) counts seven sacraments: Baptism, Confirmation, the Eucharist, Penance, the Anointing of the Sick, Holy Orders and Matrimony. The Westminster Confession says “There be only two sacraments ordained by Christ our Lord in the Gospel; that is to say, Baptism, and the Lord's Supper,” and Baptist bodies count two ordinances (Baptist Faith and Message). Canon 1024 says “Only a baptized male validly receives sacred ordination” (canon law). Protestant traditions commonly describe pastors as ministers of Word and Sacrament. How to find a church covers the questions to ask any congregation.

Why don't Protestants pray to Mary? The Catechism says Marian devotion “differs essentially from the adoration which is given to the incarnate Word and equally to the Father and the Holy Spirit,” and Catholic sources describe asking Mary or a saint to pray as intercession that depends on Christ (paragraphs 963 to 975). The Westminster Confession says “Prayer is to be made to God alone, and not to any creature,” and Article XXII (1571) rejects “Invocation of Saints.” Evangelical statements commonly honor Mary as Jesus' mother and read 1 Timothy 2:5 as naming Christ the sole mediator.

Salvation, and where they have said the most together

In 1999 the Lutheran World Federation and the Catholic Church signed a Joint Declaration: “By grace alone, in faith in Christ's saving work and not because of any merit on our part, we are accepted by God and receive the Holy Spirit, who renews our hearts, while equipping and calling us to good works.” The World Methodist Council joined in 2006, the Anglican Consultative Council in 2016 and the World Communion of Reformed Churches in 2017. Open questions remain about justification and sanctification and human cooperation, and critics on each side said it did not settle everything. Catholics read Ephesians 2:8-10 and James 2:14-26 as grace, faith and works formed by love held together; Protestants as grace through faith with works as its fruit.

On purgatory, the Catechism (1030 and 1031) describes “a final purification of the elect” after death, and the Westminster Confession and Article XXII reject it. If you are grieving, what the Bible says about grief is there.

Marrying across the two, and family

Canon 1124 requires the express permission of the competent authority for a marriage between a Catholic and a baptized non-Catholic, and Canon 1125 asks the Catholic party to promise to do all in his or her power to have the children baptized and raised Catholic (canon law). The USCCB says sharing the faith may take the form of “prayer, good example, witness to the faith in word and deed.” In the UK, the Association of Interchurch Families describes itself as “A Support Network, an Information Service for interchurch couples.” The decision about a wedding, baptism or upbringing belongs to the couple with their priest or minister.

Before an invitation, the practical question is what the morning will look like.

What people say, and what lands badly

On Reddit's r/Catholicism, in one thread, a commenter wrote “They don't worship Mary, they venerate Mary.” and another “Catholics believe in one baptism.” On Reddit's r/Protestantism, posted June 1, 2023, someone asked “why does everything need to be catholic vs protestant.”

Some readers report being told “Your baptism does not count,” or that Catholics are not Christians, or that Protestants are not a real church. Those are what people say they heard, not the teaching of either tradition; the Catechism line above and Unitatis Redintegratio speak of other Christians. Lines you can use instead: “Tell me what your church teaches about that, and I'll tell you what mine does.” “We share a creed and we differ on some things, and both are true.” Historic conflicts, including Northern Ireland, were political and religious, and they do not describe any living neighbor.

One small next step

Write down the one question you most want answered, then ask the priest, minister or relative who knows the tradition, in a conversation where you are not asked to choose. If you are about to walk into a service, going to church for the first time covers a first visit, and church hurt is for the reader who was told they do not count.

If a church or a family has hurt you and you need a person tonight: in the United States, call or text 988; in Canada, call or text 9-8-8; in the UK and Ireland, Samaritans is 116 123; in Australia, Lifeline is 13 11 14; anywhere else, Find A Helpline lists services by country.

Bible Nudge gives a person one passage with the story around it, and Find a passage is where to start.
