Some people use the word catholic. 

The word catholic means "universal." 

The word catholic comes from a Greek word. It means "universal" or "general." 

Some groups have different ways of being catholic. The Roman Catholic Church is one large group. Other groups, like the Eastern Orthodox Church, also use the term. Some Protestant groups, like Lutherans, use it too. They believe they follow the same old truths. They call themselves heirs of the apostolic faith. This means they follow the teachings of the apostles.
Many of these groups share special ways to worship. They might use bread and wine in a service. This is called the Eucharist. They may also use candles, music, or incense. Some use the sign of the cross. 
The word catholic comes from an ancient Greek word. It means "universal" or "general." 

Many different groups use this word in their own ways. The Roman Catholic Church is a very large group. However, other groups like the Eastern Orthodox Church also use the term. Some groups that split from Rome, like Anglicans, use it too. 
History shows that the early church had many big changes. At first, some leaders believed the church was organized under five main cities. These were Rome, Alexandria, Antioch, Constantinople, and Jerusalem. The bishop of Rome was often seen as a leader among them. 
Groups that claim catholicity often share certain traditions. They might use formal sacraments to show God's grace. A sacrament is a visible sign of something invisible. 
Understanding catholicity helps us see how many groups connect. Even when churches disagree, they often use the same ideas. They might all believe that Jesus is divine. They might all value the teachings from early councils. Some groups focus on the authority of the Pope in Rome. Other groups focus on being part of the whole body of believers. It is a way to talk about being part of something huge. It connects many different people across the whole world.
Catholicity is a concept regarding beliefs and practices that are widely accepted by many Christian denominations. The term comes from the Ancient Greek word *katholikos*, which means "general" or "universal." 

Different groups use the term "catholic" in various ways. The capitalized word "Catholic" often refers specifically to the Roman Catholic Church. However, many other denominations also claim the trait of catholicity. This includes the Eastern Orthodox Church and the Oriental Orthodox Church. The Assyrian Church of the East also uses the term. Even groups that split from Rome, such as Anglicans and Lutherans, use the word. They use it to show they are "heirs of the apostolic faith." 
History shows that the early church underwent several major divisions, known as schisms. One theory is the Pentarchy, which organized the church under five patriarchs. These leaders were based in Rome, Alexandria, Antioch, Constantinople, and Jerusalem. The bishop of Rome was often recognized as first among them. 
Early theological disagreements also caused significant splits. The Council of Ephesus in 431 addressed the nature of Jesus. It affirmed that Mary is the *Theotokos*, or "God-bearer." Those who disagreed with this ruling formed the Assyrian Church of the East. Later, the Council of Chalcedon in 451 dealt with the nature of Christ's divinity and humanity. This council declared that Christ has two natures without division or separation. The rejection of these terms led to the formation of the Oriental Orthodox Churches. 
A massive division occurred in 1054, known as the East-West Schism. This split divided the church into a Western camp and an Eastern camp. The West included much of Western Europe, such as Spain, France, and England. The East included Greece, Russia, and parts of the Slavic lands. 
Many groups that claim catholicity share specific religious practices. They often follow an episcopal polity, which is a system of church government led by bishops. They also value apostolic succession, the idea of an unbroken chain of ministry. 
Sacraments are a vital part of this shared identity. In the Roman Catholic tradition, there are seven sacraments. These include Baptism, Eucharist, and Matrimony, among others. 
Ultimately, catholicity relates to how different groups view the entire body of believers. It connects the history of the early church to modern religious life. Some use the term to define the orthodox mainstream of Christianity. Others use it to describe the universality of their specific confession. By studying these terms, we can see how different traditions attempt to claim a connection to the historic, universal faith. It remains a way to discuss the vast and diverse assembly of people united to Christ.
