Understanding the Catholic Tradition Within the Christian Faith
When people search for “Christianity vs. Catholicism,” they are often trying to understand an important question: Are Catholics Christians?
The answer is yes.
Catholicism is one of the major traditions within Christianity. Catholics believe in Jesus Christ, the Bible, the Trinity, the death and resurrection of Jesus, and the central message of the Christian Gospel.
At the same time, Catholic Christianity has beliefs and practices that are different from those found in many Protestant churches and other Christian traditions.
Understanding these differences does not have to create division. In fact, learning about them can help Christians appreciate both what they share and what makes their traditions unique.
What Is Christianity?
Christianity is the broad faith centered on Jesus Christ.
Christians believe that Jesus is the Son of God, that He died for humanity’s sins, rose from the dead, and offers salvation and eternal life.
Christianity includes many different traditions and denominations.
These include:
- Catholic Christianity
- Eastern Orthodoxy
- Anglican Christianity
- Lutheranism
- Presbyterianism
- Methodism
- Baptist churches
- Pentecostal churches
- Non-denominational churches
- Many other Christian traditions
Because Christianity includes so many traditions, there isn’t always one answer to questions about Christian beliefs outside of the central doctrines shared by most Christians.
What Is Catholicism?
Catholicism is the Christian tradition centered around the Catholic Church.
The Catholic Church understands itself as continuing the faith and ministry of the apostles and places a strong emphasis on Scripture, Sacred Tradition, and the teaching authority of the Church.
The Pope serves as the bishop of Rome and is regarded by Catholics as the successor of Saint Peter and the visible leader of the Catholic Church.
Catholic worship is centered around the Mass, especially the Eucharist.
What Do Catholics and Other Christians Have in Common?
Despite important differences, Catholics share many fundamental beliefs with other Christians.
Catholics and most other Christians believe in:
One God
God is understood as one God in three Persons: Father, Son, and Holy Spirit.
Jesus Christ
Jesus is central to the Christian faith. Christians believe He is the Son of God who became human, died on the cross, and rose from the dead.
The Resurrection
The resurrection of Jesus is at the heart of Christianity.
The Bible
Catholics and other Christians recognize the Bible as sacred Scripture.
Prayer
Prayer is an essential part of Christian life.
Baptism
Baptism is an important Christian practice and sacrament.
The Gospel
Christians believe that humanity needs God’s grace and that salvation is ultimately found through Jesus Christ.
These shared beliefs form a powerful foundation of Christian unity.
The Bible and Church Tradition
One of the major differences between Catholicism and many Protestant traditions involves authority.
Catholics recognize both Sacred Scripture and Sacred Tradition as important sources of Christian teaching. The Catholic Church also has a teaching authority, often called the Magisterium, which interprets Scripture and Tradition.
Many Protestant churches emphasize Scripture alone, commonly expressed by the phrase sola Scriptura, as the final authority for Christian doctrine.
However, Protestant traditions differ among themselves regarding exactly how Scripture should be interpreted and how church authority should function.
This difference in understanding authority has influenced many other theological disagreements.
The Catholic Sacraments
Catholicism recognizes seven sacraments:
- Baptism
- Confirmation
- Eucharist
- Reconciliation
- Anointing of the Sick
- Holy Orders
- Matrimony
Catholics understand these sacraments as important means through which God’s grace is given.
Many Protestant churches recognize only two ordinances or sacraments instituted directly by Christ: Baptism and the Lord’s Supper.
Again, Protestant beliefs vary considerably, so not every Protestant church explains these practices in exactly the same way.
The Eucharist
The Eucharist is one of the most important distinctions between Catholicism and many Protestant traditions.
Catholics believe that during the Mass, the bread and wine truly become the Body and Blood of Christ while retaining the appearances of bread and wine. This teaching is known as transubstantiation.
Many Protestants understand Communion differently.
Some view it primarily as a memorial of Christ’s sacrifice. Others believe Christ is spiritually present, while some traditions hold views that are closer to the Catholic understanding.
The Lord’s Supper is therefore important across Christianity, but Christians understand what happens during Communion differently.
Mary and the Saints
Catholics have a special devotion to Mary, the mother of Jesus.
Catholics honor Mary as the Mother of God and believe that she has a unique role in God’s plan of salvation.
Catholics also honor the saints and may ask them to intercede—to pray for them before God.
This can be unfamiliar to many Protestant Christians.
Most Protestants emphasize praying directly to God through Jesus Christ and generally do not ask saints to intercede for them.
Catholics, however, do not believe that saints replace God. Asking a saint to pray is understood as similar to asking another Christian to pray.
What About Salvation?
Salvation is another area where Catholic and Protestant language can sometimes sound different.
Catholic teaching emphasizes that salvation is God’s gift of grace. Human beings cannot earn salvation by their own power.
At the same time, Catholics believe that faith must be lived through love and that Christians are called to cooperate with God’s grace.
Many Protestant traditions strongly emphasize justification by faith, teaching that people are justified before God through faith rather than by earning salvation through good works.
There are important theological differences between Catholic and Protestant understandings of justification, grace, faith, works, and sanctification.
Yet both traditions teach that salvation ultimately depends upon God’s grace and the saving work of Jesus Christ.
Why Did Catholicism and Protestantism Separate?
The major division between Western Catholicism and Protestantism developed during the Protestant Reformation in the 16th century.
Reformers such as Martin Luther challenged aspects of Catholic teaching and church practice.
Arguments developed over issues including:
- Church authority
- The role of Scripture
- Salvation and justification
- The sacraments
- Church leadership
- Religious practices
The Reformation eventually resulted in the formation of many Protestant churches.
It was a complicated historical period involving theology, politics, culture, and social change.
The divisions created during that period continue to influence Christianity today.
Are Catholics and Protestants Both Christians?
Yes.
Catholics are Christians.
Protestants are Christians.
Eastern Orthodox Christians are Christians.
Other historic Christian traditions also identify themselves as followers of Jesus Christ.
While Christians may disagree about important doctrines, the word Christian refers broadly to those who identify with Jesus Christ and the Christian faith.
It is therefore inaccurate to describe Christianity and Catholicism as completely separate religions.
Catholicism is a major Christian tradition.
Why Understanding Differences Matters
Learning about differences between Christian traditions can be valuable.
It can help us understand history.
It can prevent misunderstandings.
It can encourage respectful conversations.
And it can remind us that Christianity is a large and diverse family.
We don’t have to pretend that theological differences don’t exist.
At the same time, disagreement doesn’t have to become hostility.
Jesus taught His followers to love one another.
That command remains important even when Christians disagree.
What Can Christians Learn From One Another?
Catholic Christianity has a long tradition of contemplative prayer, liturgy, Christian art, sacred music, charitable service, and theological reflection.
Protestant Christianity has contributed enormously to Bible study, evangelism, missions, preaching, hymnody, and personal approaches to Scripture.
Orthodox Christianity offers a rich tradition of ancient liturgy, prayer, icons, and spiritual disciplines.
Every Christian tradition has strengths worth understanding.
Learning from one another does not require abandoning one’s convictions.
It requires humility.
Christianity in a Divided World
The world does not need Christians fighting endlessly over labels.
It needs Christians who demonstrate the character of Christ.
People are watching how believers treat one another.
They notice whether Christians show compassion.
They notice whether Christians forgive.
They notice whether Christians care for the poor, the lonely, and the suffering.
They notice whether Christians live what they preach.
The Christian faith is not simply a collection of theological arguments.
It is a life centered on Jesus.
A Prayer for Christian Unity
Heavenly Father,
Thank You for sending Jesus Christ and calling people from every nation and background to follow Him.
Help Christians of different traditions understand one another with humility and respect.
Where we disagree, give us wisdom.
Where we have been divided by pride, give us humility.
Where there has been hostility, give us love.
Help us remember what unites us: our need for Your grace, our faith in Christ, and our calling to love our neighbors.
Teach us to speak about our differences without hatred and to defend our convictions without forgetting compassion.
May Christians everywhere become known not only for what they believe, but also for how faithfully they live the love of Jesus.
In Jesus’ name, Amen.
Final Thoughts
Christianity is much bigger than one denomination or tradition.
Catholicism is not outside Christianity. It is one of Christianity’s oldest and largest traditions.
Catholics and other Christians share many essential beliefs about God, Jesus, Scripture, prayer, and salvation, while differing on important questions of authority, sacraments, worship, Mary, the saints, and the meaning of salvation.
Understanding those differences can make our faith conversations more thoughtful and respectful.
And perhaps the most important lesson is this:
We can seek truth without losing love.
We can hold convictions without treating others as enemies.
And we can remember that at the center of Christianity is not a denomination, a building, or a label.
At the center is Jesus Christ.
