1.3 Christianity as Gospel, Revelation, and History

Christianity is often described as a religion, worldview, moral system, or historical movement. All of those descriptions can be useful, but Christianity describes its central message as gospel.

The word gospel means “good news.” In Christianity, the gospel is the announcement that God has acted through Jesus Christ to rescue humanity from sin, evil, death, and separation from God.

Christianity does not present itself mainly as a system of self-improvement. It is not only about becoming more moral, more disciplined, or more spiritual. Christianity does include moral teaching, but its central claim is that human beings need more than advice. They need salvation.

Christianity teaches that the human problem is deeper than ignorance, bad habits, or social disorder. Human beings are affected by sin, which Christianity understands as wrongdoing, broken relationship with God, disorder within the human heart, and a force that damages human life, communities, and creation.

The gospel claims that God did not abandon humanity in this condition. Christians believe God acted in history through Jesus Christ. Jesus revealed God’s character, taught about God’s kingdom, lived faithfully, died on the cross, and rose from the dead.

This is why Christianity is also a revelation-based religion. Christians believe human beings do not have to discover everything about God by reason, observation, philosophy, or personal experience alone. They believe God has made Himself known.

Christianity usually speaks about revelation in more than one way. General revelation refers to the idea that something about God can be known through creation, conscience, moral awareness, and the order of the world. Special revelation refers to God’s more direct communication through specific people, events, and messages.

For Christians, special revelation includes God’s work through Israel, the prophets, Scripture, and most fully Jesus Christ. The Bible is central because Christians believe Scripture records God’s work in history, His commands, His promises, His warnings, and His plan of salvation.

Christianity also claims that Jesus Christ is the fullest revelation of God. Christians do not view Jesus only as a teacher of religious ideas. They believe His life, character, teachings, death, and resurrection reveal who God is and what God is doing to save humanity.

Christianity is also a historical faith. It does not only offer timeless moral principles or spiritual reflections. It makes claims about real historical events: the life of Jesus, His crucifixion under Roman authority, His resurrection, the witness of the apostles, and the formation of the early church.

For Christians, the death and resurrection of Jesus are central to the Christian message. Christianity teaches that through Jesus’s death, God deals with sin, and through Jesus’s resurrection, God defeats death and opens the way to new life.

Christians call Jesus “Savior.” Salvation is not understood as something human beings can fully achieve by intelligence, morality, rituals, politics, or effort. It is understood as a gift of God’s grace, received through faith and lived out in a transformed life.

Different Christian traditions explain salvation in different ways. Catholics, Orthodox Christians, Protestants, Evangelicals, Pentecostals, and other Christian groups may emphasize different aspects of grace, faith, works, sacraments, repentance, holiness, and union with Christ. Those differences will be discussed later in this course.

Even so, the basic gospel claim is shared across historic Christianity: God has acted through Jesus Christ to bring forgiveness, reconciliation, and new life.

The gospel also has a future dimension. Christianity teaches that history is moving toward judgment, restoration, resurrection, and the renewal of creation. Christian hope is not only about individual forgiveness after death. It is also about God’s kingdom, the defeat of evil, and the promise that God will ultimately make all things right.

In this way, Christianity connects gospel, revelation, and history. It claims that God has spoken, acted, and revealed Himself through Jesus Christ in order to save, forgive, restore, and bring hope to the world.

In section 1.4, we will look at Christianity within the Abrahamic tradition and the global church.
