Are Catholics Christian? Biggest Differences

The topic of Catholics not being true Christians has been a difficult topic for many decades to address. Due to the teachings and practices of the Catholic Church, many denominations argue that Catholics are not Christians.

This type of assertion is not biblical, as we cannot know a person's heart as God can. As believers, we do not need to judge others based on their denomination.

Are Catholics Christian?

Catholicism has many unbiblical practices and teachings, such as purgatory, sacraments, and the rosary, but this does not mean a Catholic person is not a Christian.

A person becomes a Christian by placing faith in Christ by believing that He died for their sin, was buried, and rose again (John 3:16-17; Romans 10; 1 Corinthians 15:1-4).

If a person accepts Jesus as their Savior and Lord, then they are a true Christian. It doesn't matter if that person attends a Catholic Church, a Baptist Church, a Methodist Church, or a Moravian Church.

In other words, it doesn't matter what denomination a person is a part of, but rather if they have placed faith in Christ. Placing faith in Jesus is the only way a person is a Christian.

Therefore, a Catholic can be a Christian if they have placed faith in Christ as their Savior and Lord. This does not mean their theology is perfect because much of Catholicism is not biblically based.

Teachings such as purgatory, sacraments, and praying the rosary are teachings and beliefs within Catholicism — not the true Word of God. The theology of Catholics differs from Christian theology drawn from the Bible, but anyone can be a Christian if they have placed faith in Jesus as their Savior and Lord.

Catholicism vs Christianity

There are many unorthodox teachings within the Catholic Church. The first one that comes into our minds is the concept of the Catholic teaching of purgatory. The Bible never tells us that purgatory is real.

The concept of purgatory was crafted and developed by the Catholic Church over time. All of our information needs to come from the Bible because we know it is the true Word of God.

Catholics use information from sources outside of the Bible, which cannot be trusted because they are not the inspired Word of God.

Purgatory is taught within Catholic churches to instill the idea that there is a waiting period that all individuals will have to go through before going to heaven or hell. The Bible tells us differently as we either go to heaven or hell when we die.

In the same way, the Catholic Church teaches the practice of sacraments and praying the rosary. The Bible never directly speaks of sacraments. The Lord's Supper is not the same sacrament as the Catholic church.

Sacraments, as taught in the Catholic Church, have no biblical base. Similarly, the teaching of praying the rosary is taught across the world in Catholic churches. The Bible never teaches us to pray the rosary.

The concept of praying the rosary came through the teachings of the early popes because Dominican Pope Pius V claimed he had a vision of Mary telling him to pray the rosary, and Mary supposedly gave him the first rosary.

Despite this belief circulating through the Catholic church, God never tells us to pray the rosary. The Lord teaches us how to pray in Matthew 6, yet He never tells us to use a rosary to pray. In fact, the Lord advises against repetitious prayers as the pagans did (Matthew 6:7). 

A significant difference between the Christian Church and the Catholic Church is the emphasis placed upon Mary. There is an unhealthy amount of emphasis placed upon Mary in the Catholic Church. Mary was an important person, yet she is not to be worshipped, and she is not God.

In Catholicism, Mary is often seen as an intercessor, someone who can pray on behalf of believers. Devotion to Mary includes practices such as the Rosary, where Catholics recite prayers and meditate on specific events in the lives of Jesus and Mary.

The Catholic Church tends to place Mary on an untouchable pedestal and teaches that Mary kept her virginity throughout her life. Mary was a virgin when she conceived Christ, yet after she had relations with her husband, she was no longer a virgin.

The Bible teaches us that Jesus is the One we should worship — not Mary. If Mary were here today, she would point all Catholics to worship Jesus, not her. Mary was not a divine woman. Rather, she was a human being just like you and me.

Biggest Difference Between Catholic and Christian

The most significant difference between Catholic and Christian denominations is the acceptance of the authority of the Pope. 

The Catholic Church recognizes the Pope, also known as the Bishop of Rome, as the supreme authority on matters of doctrine, morals, and Church governance. The Pope is considered the Vicar of Christ on Earth and the visible head of the Catholic Church. Catholics believe in the Pope's infallibility when speaking ex cathedra on matters of faith and morals.

Papal infallibility is a doctrine within the Catholic Church that asserts that, under certain specific conditions, the Pope is considered to be incapable of making errors or teaching false doctrines in matters of faith and morals. 

The role of the Pope is multifaceted and carries great significance within the Catholic Church. While he is a human leader, his authority is believed by Catholics to be guided by the Holy Spirit to preserve the Church's teachings and lead the faithful on their spiritual journey.

Do Catholics Believe in Jesus?

Catholics believe in Jesus Christ as the central figure of their faith. In fact, all Christian denominations, including Catholicism, regard Jesus as the Son of God and the savior of humanity.

Jesus is seen as actively present in the sacraments, particularly in the Eucharist, where Catholics believe in the real presence of Jesus in the consecrated elements of bread and wine.

The Catholic Church has a rich theological tradition that emphasizes the significance of Jesus' life, death, and resurrection in the salvation of humanity.

However, understanding these traditions is different than having a personal relationship with Jesus Christ.

Building a personal connection with our Lord is a journey of faith, prayer, and reflection. Immerse yourself in the Gospels, the beautiful narratives of Jesus' life, teachings, and miracles. Read and meditate on passages that resonate with your heart.

Anyone who places faith in Christ is eternally saved. Acts 4:12 tells us, “Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.”
