6.4 The New Testament:
Jesus, the Apostles, the Church, and the End of the Age
The New Testament is the second major section of the Christian Bible.
It focuses on the life and teachings of Jesus Christ, the growth of the early Christian movement, and the beliefs that shaped the first Christian communities.
The Old Testament primarily tells the story of God’s covenant relationship with Israel, while the New Testament centers on Jesus and what Christians understand to be the fulfillment of God’s promises through Him.
The twenty-seven books of the New Testament were originally written in Koine Greek, the common language of much of the eastern Mediterranean during the first century AD. Most scholars date these writings to approximately AD 50 to AD 100, placing them within the lifetime or living memory of the first generations of Christians.
Although the New Testament contains only twenty-seven books, these writings have profoundly shaped Christian theology, worship, ethics, and history.
Like the Old Testament, the New Testament is a collection of different kinds of literature written by multiple authors for different audiences and purposes.
The Historical Setting
The events of the New Testament take place during the first century AD, when Judea and the surrounding regions were part of the Roman Empire. Although the Jewish people had returned from exile centuries earlier and rebuilt the Temple in Jerusalem, they remained under Roman rule. This period of Jewish history is commonly known as the Second Temple period.
Many Jews hoped that God would send the promised Messiah who would restore Israel, establish justice, and fulfill God’s promises. Different Jewish groups held different expectations about what this Messiah would be like. Some expected a political ruler. Others anticipated a priestly leader, a prophet, or a divinely appointed deliverer.
Against this historical backdrop, Jesus of Nazareth began His public ministry. His life and teachings became the foundation of Christianity.
Jesus Christ
The central figure of the New Testament is Jesus of Nazareth.
The title Christ comes from the Greek word Christos, meaning “Anointed One,” and corresponds to the Hebrew word Messiah.
Christians believe Jesus is the promised Messiah foretold in the Old Testament.
The first four books of the New Testament are known as the Gospels. The word gospel comes from the Greek word euangelion, meaning “good news.” Christians use this word to describe the good news of God’s kingdom and salvation through Jesus Christ.
The four Gospels—Matthew, Mark, Luke, and John—describe the life, teachings, miracles, death, and resurrection of Jesus.
Matthew, Mark, and Luke are often called the Synoptic Gospels because they share many of the same events and follow a broadly similar outline of Jesus’ ministry. The Gospel of John covers many of the same central events but presents Jesus’ ministry with a distinctive style, vocabulary, and theological emphasis. Together, the four Gospels provide the primary source of information about Jesus’ life.
Much of Jesus’ teaching focused on the Kingdom of God.
He taught through sermons, conversations, and parables—short stories that used familiar situations to communicate deeper spiritual truths.
Many of His teachings emphasized:
- Love of God and neighbor
- Forgiveness
- Repentance
- Humility
- Mercy
- Justice
- Faithfulness
- Caring for the poor and vulnerable
Jesus’ ministry attracted both devoted followers and strong opposition.
He was eventually crucified by Roman authorities. Christians believe that Jesus rose from the dead, an event that stands at the center of Christian faith.
Different scholars approach these events from different historical and theological perspectives, but the death and resurrection of Jesus remain foundational to Christianity.
The Apostles and the Early Church
After Jesus’ death and resurrection, His followers continued spreading His teachings.
Among His closest followers were the apostles. The word apostle comes from a Greek word meaning “one who is sent.” In the New Testament, the apostles were commissioned by Jesus to proclaim His message and help lead the early Christian movement.
The Book of Acts describes how Christianity spread from Jerusalem throughout the Roman world. It records events such as:
- The coming of the Holy Spirit at Pentecost
- The growth of the early church
- Missionary journeys
- Persecution of Christians
- The conversion of Paul
- The spread of Christianity among both Jews and Gentiles
One of the central questions facing the early church was how Gentiles (non-Jewish converts) could become followers of Jesus.
The New Testament records significant discussions and disagreements about the relationship between the Jewish Law and the growing Christian movement.
These debates helped shape Christianity as it expanded beyond its Jewish origins into a global religion.
The Letters of the New Testament
Much of the New Testament consists of letters, often called epistles. In fact, the earliest books of the New Testament to be written were probably several of Paul’s letters—Galatians, 1 Thessalonians, 1 Corinthians, 2 Corinthians, and Romans—which were composed before the four Gospels.
These letters were written to churches and individual believers throughout the Roman world. Many are traditionally attributed to the apostle Paul, while others are associated with figures such as Peter, James, John, and Jude.
The letters address practical and theological questions including:
- Faith
- Salvation
- Christian living
- Church leadership
- Unity
- Moral conduct
- Worship
- Perseverance during suffering
Rather than presenting a systematic theology, these letters often respond to specific situations and challenges faced by early Christian communities. They still remain an important source of Christian teaching and doctrine today.
The Book of Revelation
The final book of the New Testament is Revelation. Unlike most other New Testament books, Revelation belongs primarily to a literary genre known as apocalyptic literature. It uses vivid symbolism, visions, numbers, and dramatic imagery to communicate its message.
Revelation addresses themes such as:
- The struggle between good and evil
- God’s ultimate justice
- The perseverance of believers
- Final judgment
- The renewal of creation
- The hope of God’s eternal kingdom
Because Revelation contains highly symbolic language, Christians have interpreted it in many different ways throughout history. Some understand it primarily as describing events in the first century. Others believe it predicts future events. Still others understand it as portraying timeless spiritual realities that apply throughout history. These differing interpretations remain an important area of Christian discussion.
Major Themes of the New Testament
Although the New Testament contains many different books and authors, several themes appear repeatedly.
- The Kingdom of God
- Salvation
- Grace
- Faith
- Love
- The Church
- Hope
These topics are discussed in depth in other modules.
The New Testament consistently points toward the future hope of resurrection, the renewal of creation, and the fulfillment of God’s kingdom. These themes have shaped Christian belief and practice for nearly two thousand years.
The New Testament in Christianity
For Christians, the New Testament provides the primary source of information about Jesus Christ and the beginnings of Christianity.
Jesus, His disciples, and the earliest Christians were all Jews, and every book of the New Testament emerged from the world of first-century Judaism under Roman rule. As Christianity spread among Gentiles, it gradually developed into a distinct global religion while continuing to look back to the Scriptures and history of Israel.
The writings of the New Testament form the basis for many Christian beliefs about salvation, worship, ethics, church life, and the future.
At the same time, Christians do not always interpret the New Testament in the same way. Different traditions often disagree about theology, church authority, baptism, communion, spiritual gifts, prophecy, and many other topics. Despite these differences, all major branches of Christianity recognize the same twenty-seven books of the New Testament as Scripture.
Conclusion
The New Testament tells the story of Jesus Christ, the growth of the early church, and the hope that shaped the first Christian communities.
Through the Gospels, Acts, the letters, and Revelation, it presents the beliefs, teachings, and experiences that became the foundation of Christianity.
Together with the Old Testament, the New Testament forms the Christian Bible and provides the central source for Christian faith, theology, and practice.
In section 6.5, we will examine how the books of the Bible became recognized as Scripture and how the biblical canon developed over time.
