Gain insights into the rich history and global impact of both Catholicism and Christianity.

Catholicism and Christianity are two major branches of the Christian faith. While many consider Catholicism to be a form of Christianity, there are distinctions that set them apart. In this article, we will explore the biblical definition of Christianity, delve into Catholic beliefs and practices, highlight the differences in marriage traditions, explore the biggest distinctions between the two, and investigate the variations in their respective Bibles. By the end, you’ll have a clearer understanding of the relationship between Catholicism and Christianity, and their respective impacts on the world.

Nature of AuthorityTypically, most Christian denominations place primary authority in the Bible, the inspired word of God, and believe that individuals can have a direct relationship with God. Some denominations may have certain established hierarchies, but this can greatly vary.Catholicism, a branch of Christianity, believes in the authority of the Bible but also in the authority of Church Tradition and the Magisterium (the teaching authority of the Church, primarily exercised by bishops and the Pope). The Pope, as the Bishop of Rome, is seen as the spiritual successor to Saint Peter and holds a special authority.
SacramentsProtestant Christianity generally recognizes two sacraments: baptism and the Lord’s Supper (or Communion). However, this can vary among different denominations.Catholicism recognizes seven sacraments: baptism, confirmation, the Eucharist (Communion), reconciliation (confession), anointing of the sick, marriage, and holy orders.
The Eucharist (Communion)Many Christian denominations view Communion as a symbolic act that commemorates the Last Supper and Christ’s death. The bread and wine are seen as symbols of Christ’s body and blood.Catholics believe in Transubstantiation, which is the belief that the bread and wine used in the Eucharist become the actual body and blood of Christ when consecrated during Mass. The substances do not physically change, but Catholics believe their essence does.
Saints and MaryIn most Christian denominations, the term “saint” is used more broadly to refer to anyone who is a believer in Christ. Mary, the mother of Jesus, is respected, but not accorded any special status beyond being his earthly mother.Catholics honor Mary with a special status as the “Mother of God” and “Queen of Heaven.” They also venerate saints and believe that they can intercede with God on behalf of believers. The process of declaring someone a saint is formal and thorough in the Catholic Church.
Views on SalvationIn Protestant Christianity, salvation is often understood as being by faith alone (“sola fide”) — a personal faith in Jesus Christ is what leads to one’s salvation.In Catholicism, faith in Jesus is essential for salvation, but Catholics also believe that faith must be lived out through love and obedience to the commandments of God and the Church. Good works, participating in the sacraments, and the intercession of the Church are seen as playing a role in salvation.
All Scripture is God Breathed

Please note that “Christianity” is a broad term that encompasses a multitude of denominations, including Catholicism. The comparisons made here are more aligned with Protestant Christianity, and even within that, there is a significant range of beliefs and practices. It’s always crucial to remember the diversity within these categories.

These are some of the major beliefs of the Catholic Church, though this is not an exhaustive list. The catechism of the Catholic Church provides a more comprehensive overview of the Catholic faith.


Catholics, along with other Christians, embrace the doctrine of the Trinity, which teaches that God exists as three persons—Father, Son (Jesus Christ), and Holy Spirit—in one divine essence.

One notable aspect of Catholic theology is the veneration of the Virgin Mary. Catholics believe that Mary, the mother of Jesus, was a perpetual virgin and was specially chosen by God to bear His Son.

No Meat on Friday

In observance of the Catholic practice of abstinence, Catholics traditionally abstain from eating meat on Fridays as a form of penance and remembrance of Christ’s sacrifice on Good Friday.

5 Beliefs and Practices of Catholicism

Beyond the shared beliefs with Christianity, there are several specific beliefs and practices that are distinct to Catholicism.

Catholic Marriage Rules

Catholic marriage is considered a sacrament and is regarded as a lifelong commitment between a man and a woman. The union is blessed by God, and divorce is generally not accepted by the Church.

Guidelines for Marriage in the Catholic ChurchDescription
Sacrament of MatrimonyCatholic marriage is a sacrament, a divine institution that imparts grace. It symbolizes Christ’s love for the Church.
Free ConsentBoth parties must freely choose to enter into the marriage.
Lifelong CommitmentMarriage in the Catholic Church is seen as a lifelong commitment, symbolized by the vows “till death do us part.
Openness to ChildrenCouples must be open to having children, as procreation is one of the key purposes of marriage according to the Church.
FaithfulnessThe couple must commit to being faithful to each other, both emotionally and physically, for their entire lives.
Pre-Marital PreparationMost dioceses require couples to undergo a period of pre-marital preparation, sometimes referred to as Pre-Cana, to ensure they fully understand the commitment they are making.
Canonical FormThe marriage must be celebrated in accordance with the canonical form, meaning it takes place in the presence of a bishop, priest, or deacon and at least two witnesses.
No ImpedimentThere should be no canonical impediment to the marriage. This includes being of minimum age, not being closely related, not being bound by religious vows, etc.
Marriage LicenseLike any other marriage, a marriage in the Catholic Church requires a civil marriage license from the local government.
Mixed MarriagesIf a Catholic wishes to marry a non-Catholic, they usually need to receive a dispensation from their bishop. The non-Catholic partner does not have to convert, but the Catholic partner must promise to do all they can to raise their children as Catholics.

Please note that this table summarizes general guidelines. Specific practices may vary depending on the particular diocese or parish. Always consult with a priest or deacon for accurate and detailed guidance.


Catholic priests and nuns take a vow of celibacy, committing themselves to a life of dedication to God and service to the Church.

Man and Woman

Catholicism adheres to the traditional view of marriage as being between a man and a woman, following biblical teachings.

Not Divorced – But Annulled

While divorce is not typically recognized by the Catholic Church, an annulment may be granted if a marriage is deemed invalid due to certain conditions not being met.

Must Raise Children Catholic

In Catholic marriages, parents are encouraged to raise their children in the Catholic faith and provide them with a religious education.

Difference Between Catholic and Christian Marriage

While both Catholics and other Christians consider marriage a sacred institution, there are notable differences in their respective marriage traditions.

Catholic Marriage Rules

As previously mentioned, Catholic marriage is considered a sacrament, and the ceremony takes place within the context of a Catholic mass.


Non-Catholic Christian traditions often do not require clergy members to be unmarried. Pastors and ministers in these denominations can marry and have families .

Man and Woman

Many Christian denominations now recognize and perform marriages between same-sex couples, a practice not accepted within the Catholic Church.

Not Divorced – But Annulled

Some Christian denominations permit divorce and remarriage, while Catholicism does not accept divorce. However, an annulment may be granted in certain circumstances.

Must Raise Children Catholic

While some Christian parents may raise their children within their faith, it is not a requirement as it is in Catholicism.

Biggest Difference Between Catholic and Christian

While Catholicism and other Christian traditions share a common foundation in Jesus Christ, there are significant differences that distinguish them.


Baptism is a fundamental Christian rite of initiation, symbolizing the cleansing of sins and entry into the Christian faith. While all Christians practice baptism, the specific rituals and beliefs surrounding the sacrament may vary among denominations.

Dress of Clergy

Catholic clergy, including priests and bishops, are often recognized by their distinctive clerical attire, such as cassocks and clerical collars. In contrast, non-Catholic Christian clergy may dress more casually, reflecting the traditions of their specific denomination.

Head of Church

Building Structures

Catholic churches are often characterized by their ornate architecture and elaborate decorations, reflecting the reverence and significance attached to the sacraments. Non-Catholic Christian churches may vary in architectural style and adornments.

Global Outreach Over the Ages

Catholicism has a long history of global outreach and missionary work, resulting in a widespread presence in many countries. While other Christian denominations also engage in missionary activities, the scale and historical impact of Catholic missions are significant.

Difference Between Catholic and Christian Bible

While both Catholics and other Christians follow the Bible as a sacred text, there are differences in the composition of their respective Bibles.

Deuterocanonical Books

The Catholic Bible includes additional books known as the Deuterocanonical or Apocryphal books, which are not found in Protestant Bibles.

7 Books in Catholic Bible Not in Protestant

These seven books include:

  1. Baruch
  2. Judith
  3. 1 and 2 Maccabees
  4. Sirach (Ecclesiasticus)
  5. Tobit
  6. Wisdom (Wisdom of Solomon)

Final Thoughts

Catholics hold unique practices and traditions that reflect their rich history and doctrine. Understanding these differences can foster greater appreciation for the diversity within the Christian faith and its impact on the lives of believers worldwide.

How to be saved according to the Bible    In order to understand how to be saved, we first need to understand what salvation is. Salvation is when God forgives our sins and gives us eternal life. It's a free gift from God that we can't earn on our own. So how do we receive this gift? The Bible tells us that there are six steps: hearing, believing, repenting, confessing, repenting again, and believers baptism. Let's break each one of these down.     Hearing - The first step is hearing the gospel. The gospel is the good news that Jesus died on the cross for our sins and rose again. This news must be heard in order for us to believe it.     Believing - Once we hear the gospel, we must believe it. This means that we trust that Jesus is who He says He is and that He can save us from our sins.     Repenting - Once we believe the gospel, we must repent of our sins. This means that we turn away from our sin and start living for God.     Confessing - After we repent of our sins, we need to confess them to God. This means that we tell God all of the sinful things we have done and ask Him for forgiveness.     Believers Baptism - The final step is believers baptism. This is when a person who has already believed and repented is baptized in water as an outward sign of their inward decision to follow Christ. Baptism doesn't save us, but it's an important step of obedience for every Christian.     Discipling others -  Finally, once we have received salvation through these steps, it's important that we continue to grow in our faith and share the gospel with others so they too can be saved.      These are the six steps required for salvation according to the Bible: hearing, believing, repenting, confessing, repenting again, and believers baptism. If you have never done these things or if you're not sure if you've done them correctly, I encourage you to talk to a pastor or other Christian friend who can help guide you through these steps. Salvation is a free gift from God, but it's one that we need to take intentional steps to receive. Don't wait another day - start your journey towards salvation today!
