Christianity

Overview

Christianity is a monotheistic religion that teaches that Jesus is the Son of God and rose from the dead. It is the world's largest religion, with billions of followers around the globe. Christians believe that Jesus came to help people, as told in the Old Testament and the New Testament.

History

The faith began in the 1st century after Jesus' death. It started as a small group in the area of Judaea and later spread across the Eastern Mediterranean. Over time, important moments helped shape Christian beliefs, like the Edict of Milan, which let Christians worship freely.

Main Branches

Today, Christianity has three main branches: Catholicism, Protestantism, and Eastern Orthodoxy. It has had a big impact on Western civilization, especially in Europe. While the number of Christians is changing in different places, the faith continues to grow in parts of Africa and Asia.

Etymology

Further information: Christ (title)

Early followers of Jesus called themselves "The Way." The word "Christian" was first used in the city of Antioch to describe people who followed Jesus. This term means "followers of Christ." The name Jesus comes from ancient languages, with roots in Hebrew and Aramaic words.

History

Christianity started as a small group of Jewish people who followed Jesus in the 1st century AD. They believed Jesus was the Son of God and had come back to life. These early Christians were mostly Jewish and met in Jerusalem, hoping Jesus would return.

As news about Jesus spread, more people who were not Jewish joined. A leader named Paul traveled far and wide, teaching that anyone could become a Christian by believing in Jesus, not just by following Jewish rules. Over time, Christianity grew and developed its own beliefs and ways of doing things, becoming different from Judaism.

In the years that followed, Christianity spread through the Roman Empire and beyond. Leaders known as Church Fathers wrote about Christian beliefs, and meetings were held to decide important teachings. Christianity faced hard times, including when Roman rulers made it difficult for Christians, but it also gained support from important leaders like Emperor Constantine. As Christianity grew, it shaped art, culture, and daily life in Europe and around the Mediterranean.

These gatherings usually follow a pattern. People meet, often on Sundays, to read from important books called the Old and New Testaments, especially stories about Jesus. There is often a talk based on these readings. The group may sing songs, say prayers together, and share a special meal to remember Jesus' last meal with his followers. This meal, called the Eucharist, includes bread and wine or juice.

Christian groups have worked together for many years to become closer. In the 1900s, they did this in two ways. One way was more teamwork between groups, like the World Evangelical Alliance, started in 1846, or the Edinburgh Missionary Conference in 1910. Another way was combining churches into one. For example, churches in Canada joined in 1925, and churches in Australia joined in 1977.

The Christian Flag was made to stand for all of Christianity. Many Christian groups agree on important teachings, shown in The Common Catechism. Some communities, like the Taizé Community in France, bring together people from different Christian traditions to work for peace. Leaders from different churches have worked to forget old disagreements.

Sadly, some Christians face unfair treatment because of their faith. This happens in different parts of the world. Some people work to explain and defend Christianity.
