Catholicism and Christianity are two terms that are often conflated, but there are important differences between the two. Catholicism is a branch of Christianity, and Catholics are Christians, but not all Christians are Catholics. Catholicism is the largest of the three major branches of Christianity, with about 1.3 billion followers out of an estimated 2.5 billion Christians worldwide. Catholics believe in the Trinity, the divinity of Jesus, His death and resurrection, and salvation through Him—core tenets of Christianity. However, Catholics differ from other Christian denominations in their beliefs about the sacraments, the role of the Bible and tradition, the importance of the Virgin Mary and the saints, and the papacy. Catholics view the Bible as having equal authority with the Church and tradition, while other Christians may place more emphasis on the Bible as the sole source of religious doctrine. Catholics also view salvation as a process, whereas other Christians see it as a completed status and a process.

Catholics are Christians
Catholicism is a type of Christianity. The Catholic Church is the oldest Christian institution, with its origins traced directly to Jesus Christ and the apostles. Catholics believe in the Trinity, the divinity of Jesus, His death and resurrection, and salvation through Him—core tenets of Christianity.
Catholics believe in the importance of the Virgin Mary and the saints, and the papacy. They believe that the bread and blood of Jesus become His body and blood, and that sex is for procreation, not pleasure. They also believe that salvation is by grace alone, but that faith must be expressed through love.
Catholics do not believe that the Bible is the sole source of their beliefs. Instead, they rely on Scripture plus tradition, which dates back to before the Bible was formalised in the late 4th century AD. They also use a Bible with seven additional books that were removed by later Christian churches.
Catholicism is the largest of the three major branches of Christianity, with about 1.3 billion followers out of an estimated 2.5 billion Christians worldwide. Catholics argue that theirs is the original and true form of Christianity, and that other denominations such as Protestantism sprang up when this truth was corrupted and people attempted to change it to suit their own beliefs.
However, some people argue that Catholics are not Christians. This is often because many people wrongly believe the word "Christian" is synonymous with "Protestant". It is also sometimes argued that Catholics do not believe in salvation by grace through faith alone, and that they worship Mary and statues. Catholics refute these claims, stating that they worship only God, and that they respect Mary and the saints but do not worship them.

Catholics believe in the Pope, the Trinity, and unwavering moral laws
Catholicism is considered by some Catholics to be the "authentic" or true form of Christianity. Catholics believe in the Pope, the Trinity, and unwavering moral laws.
The Pope
Catholics believe in the Pope as the successor to Christ's apostles. The Pope is believed to be infallible when it comes to matters of faith and morals, although not all Catholics agree with every Pope on every issue. The Pope is seen as a guide who helps interpret and apply the rules given by Christ.
The Trinity
Catholics believe in the Trinity, which is the concept of God as three persons in one: the Father, the Son, and the Holy Spirit. This does not mean that Catholics believe in three separate gods, but rather that God is one true God with three distinct persons or "hypostases". This belief is based on interpretations of the Bible, particularly Genesis 1, and the work of theologians like St. Augustine and St. Thomas Aquinas.
Unwavering Moral Laws
Catholics believe in a set of unwavering moral laws that are found in the Catechism of the Catholic Church. These laws are seen as "fatherly instructions" from God, guiding Catholics towards living a life of goodness and avoiding harm to oneself and others. These laws include beliefs about sexuality, such as the idea that sex is for procreation and should be open to life. Catholics believe that these moral laws are universal and based on the Bible, in contrast to other Christian denominations that may interpret the Bible differently or make decisions on a personal level.

Catholics view the Bible as having equal authority with the Church and tradition
Catholicism and Christianity are often used interchangeably, but they are not the same. Catholicism is the largest of the three major branches of Christianity. Thus, all Catholics are Christians, but not all Christians are Catholics.
Catholics view the Bible as the word of God, but they believe that the Church is the number one authority on the Bible and its interpretation. Catholics believe that the Church is the most trusted interpreter of the Bible because it was the Church that compiled the Bible, guided by the Holy Spirit. They believe that the Bible is one of three sources of authority, the other two being Church tradition and Church authority. These three sources are viewed as a three-legged stool, with no single source being more important than the other. Catholics believe that the Magisterium, or the teaching authority, is protected by the Holy Spirit, and thus believers are called to give their assent to the Church's teachings.
Catholics believe that God's revelation takes place primarily through Scripture, but also in many other ways. They believe that God's revelation has been primarily verbal and visual, through Christ the Word, and the fulfillment of Scripture. Catholics also believe that the Gospels and epistles were not written immediately after Jesus' resurrection. It took years for the writings to be compiled, and the official canon of the Bible was not established until 382 AD at the Council of Rome. Thus, tradition actually preceded Scripture.
Catholics also believe that their set of rules and moral laws, found in the Catechism of the Catholic Church, are unwavering and are not decided on a personal level. They believe that these rules were given to them by Christ and passed down through His apostles and their successors, including the Pope. Catholics also believe in the Trinity (God in three persons - the Son, the Father, and the Holy Spirit), and that the bread and blood of Jesus become exactly that as outlined in the Bible.
In summary, Catholics view the Bible as having equal authority with the Church and tradition. They believe that the Bible is the word of God but that the Church is the final authority on its interpretation. They also believe that their rules and moral laws are derived from the Bible but are interpreted and applied through the tradition and authority of the Church.

Catholics view salvation as a process, while Christians view it as a completed status
Catholicism is a type of Christianity. All Catholics are Christians, but not all Christians are Catholics. Catholicism is the largest of the three major branches of Christianity, accounting for about 1.3 billion of the world's 2.5 billion Christians.
Catholics and Christians have different views on salvation. Catholics view salvation as a process that requires many justifications along the path to heaven. They believe that salvation is by grace alone, but that faith must be expressed through love and good works. Catholics believe that salvation is accessible through repentance, faith, and baptism. They see baptism as the sacrament of justification, as it forgives all previous sins. However, they also believe that acts of justification or forgiveness may occur at other points in their lives, such as when a priest declares a sinner forgiven in confession.
Some non-Catholics believe that Catholics teach "salvation by works", but this is a misunderstanding. Catholics do not believe that they can "earn" salvation through good works. Rather, they believe that even their obedience and good works are impossible without God's grace and are, therefore, a gift from God.
In contrast, some Christians view salvation as a completed status. They believe that Christ has paid the price for their sins and that all their sins are forgiven when they find Christ. They see justification as a one-time act of God's grace that occurs when they believe in Christ.
