Definition and Origin:
The term "Christians" refers to the followers of Jesus Christ, who is recognized as the Messiah and the Son of God in Christian belief. The designation "Christian" is first recorded in the New Testament in the book of Acts. It was in Antioch that the disciples were first called Christians (Acts 11:26). This term was likely used by outsiders to describe the followers of Christ, and it eventually became the accepted name for those who adhered to the teachings of Jesus.

Biblical References:
The New Testament provides several references to Christians, both directly and indirectly. In addition to Acts 11:26, the term appears in Acts 26:28, where King Agrippa says to Paul, "In such a short time, would you persuade me to become a Christian?" . Another mention is found in 1 Peter 4:16, where Peter encourages believers, "But if you suffer as a Christian, do not be ashamed, but glorify God that you bear that name" .

Characteristics and Beliefs:
Christians are characterized by their belief in Jesus Christ as the Savior and their commitment to living according to His teachings. Central to Christian doctrine is the belief in the death and resurrection of Jesus, which provides salvation and eternal life to believers. Christians are called to love God and their neighbors, as emphasized in the Great Commandment (Matthew 22:37-39). They are also tasked with spreading the Gospel, as part of the Great Commission (Matthew 28:19-20).

Community and Worship:
The early Christian community, as described in the book of Acts, was marked by fellowship, prayer, and the breaking of bread (Acts 2:42). Christians gather for worship, which typically includes prayer, singing, reading of Scripture, and teaching. The sacraments of baptism and the Lord's Supper (communion) are central practices in Christian worship, symbolizing the believer's identification with Christ's death and resurrection.

Persecution and Suffering:
From its inception, the Christian faith has faced persecution. The New Testament records instances of early Christians being persecuted for their beliefs, as seen in the martyrdom of Stephen (Acts 7:54-60) and the imprisonment of Paul and Silas (Acts 16:23-24). Despite persecution, Christians are encouraged to remain steadfast in their faith, as suffering for Christ is seen as a form of participation in His sufferings (Philippians 1:29).

Growth and Spread:
The Christian faith spread rapidly from its origins in Jerusalem to the broader Roman Empire and beyond. The missionary journeys of Paul and other apostles played a significant role in the dissemination of Christianity. The book of Acts details the expansion of the early church and the establishment of Christian communities throughout the Mediterranean region.

Identity and Unity:
Christians are united by their faith in Jesus Christ, transcending ethnic, cultural, and social boundaries. The apostle Paul emphasizes this unity in Galatians 3:28, stating, "There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus" . This unity is a testament to the transformative power of the Gospel and the work of the Holy Spirit in the lives of believers.

Ethical Living and Moral Conduct:
Christians are called to live lives that reflect the character of Christ. The New Testament provides ethical teachings that guide Christian conduct, such as the fruit of the Spirit (Galatians 5:22-23) and the call to holiness (1 Peter 1:15-16). Christians are encouraged to be salt and light in the world, influencing society through their actions and witness (Matthew 5:13-16).
