Why Are There Four Gospels?

The Gospel of Thomas is an early collection of 114 sayings attributed to Jesus, discovered in a Coptic codex among the Nag Hammadi library in 1945 and thought to reflect an independent oral or written tradition. Unlike the canonical Gospels, it lacks narrative structure and focuses on purported sayings, some paralleled in the Synoptics and others more enigmatic. Early orthodox writers regarded the text as associated with Gnostic tendencies and therefore theologically suspect, which contributed to its exclusion from the canonical New Testament. Modern scholarship debates its date and relationship to the Synoptic tradition, with some scholars proposing early origins and others a later, sectarian composition. The work has become central to studies of early Christian diversity, Gnosticism, and sayings traditions.

The Gospel of John is the fourth of the New Testament's canonical gospels. It presents a highly schematic account of Jesus' ministry, focusing on seven 'signs' or miracles that demonstrate Jesus' divinity, and seven 'I am' discourses that highlight his divine identity. The gospel is divided into sections: a prologue introducing Jesus as the Word of God, the 'Book of Signs' detailing Jesus' ministry, the 'Book of Glory' covering his final night, arrest, trial, crucifixion, and resurrection, and a conclusion stating the gospel's purpose. The author's intent is clear: 'that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name' (John 20:31).

The Book of Acts is the fifth book of the New Testament and serves as a sequel to the Gospel of Luke. It chronicles the history of the early Christian church, beginning with the ascension of Jesus Christ and ending with Paul's imprisonment in Rome. The book is divided into two main sections: the first focuses on the ministry of Peter in Jerusalem and Samaria (Acts 1–12), and the second follows Paul's missionary journeys throughout the Roman Empire (Acts 13–28). It highlights the transition of the gospel message from a Jewish audience to the Gentiles, the empowerment of believers by the Holy Spirit, and the growth of the church despite persecutions. The book also explores the relationship between Christians and the Roman Empire, showing how Christians could obey both God and the civil authorities.

The Apocalypse of Peter is a non-canonical Christian text that describes the afterlife, particularly the torments of hell. It's a vivid and dramatic depiction of judgment and punishment, influencing later depictions of hell in Christian art and literature. The text is significant for its portrayal of early Christian beliefs about the afterlife and its impact on popular imagination. It's studied for its literary style and its reflection of early Christian eschatology. It's a valuable source for understanding the development of Christian beliefs about judgment and the afterlife.

The Gospel of Mark is the earliest of the four Gospels and provides a unique perspective on the life and teachings of Jesus Christ. It emphasizes Jesus' role as both the powerful Messiah and the vulnerable suffering servant. The narrative highlights key themes such as the Kingdom of God, the messianic secret, and Jesus' mission to suffer and die for the redemption of others. The Gospel is set against the backdrop of Jewish apocalyptic expectations and the socio-political landscape of 1st-century Judea, serving as a theological treatise and a pastoral response to a community in crisis.

Written around 180 AD, 'Against Heresies' is a five-book treatise that identifies and refutes various schools of Gnosticism and other heretical Christian thought. Irenaeus argues against the interpretations of scripture by Gnostics such as Valentinus and Marcion, and defends the orthodox Christian tradition. The work is historically significant as one of the earliest unambiguous attestations of the canonical gospel texts and some of the Pauline epistles. It remains a crucial source for understanding early Christian theology and the doctrines of Gnosticism.

The Gospel of Luke is the third Gospel in the New Testament and provides a detailed account of Jesus Christ's life, ministry, death, and resurrection. Luke, who was not an eyewitness to Jesus' ministry but carefully investigated everything from the beginning, wrote this Gospel to give believers an accurate and chronological understanding of Jesus' life. The book emphasizes Jesus' mission to seek and save the lost (Lk 19:10) and highlights his interactions with various groups, including the poor, outcasts, and marginalized. It also situates Jesus' life within the broader context of the Roman Empire, contrasting Jesus with the Roman Emperor Augustus to emphasize Jesus' role as the true savior of the world.

This book provides an in-depth analysis of the Apocalypse of John, exploring its eschatology and the context of apocalyptic literature in the Old Testament and late Jewish writings. It offers a critical and exegetical commentary, emphasizing the importance of understanding the cultural and historical context in which the book was written.

The second letter of Peter, a key figure in early Christianity, emphasizes the importance of steadfast faith and righteous living in the face of persecution. It warns against false teachers who distort the gospel and promises the eventual judgment of God. The letter highlights the importance of Scripture and the need for believers to grow in spiritual virtues like faith, virtue, knowledge, and love. It also speaks of the future return of Christ and the coming judgment.
