Definition: The New Testament is a collection of the ancient Gnostic writings in Greek, believed to be from Jesus Christ's own lips or inspired by him. The earliest versions of this text date back to at least 150 A.D., though it was not written down until the 2nd century. In his 4th-century letter, St. Paul wrote that these New Testament writings were given to him and are a direct translation from Greek to Latin, which is why they are called the "New Testament" in English. The New Testament has been compiled as follows: 1. The Gospels: These are three books of the New Testament written by Mark, Luke, and John, who served Jesus. Each of these four Gospels tells a narrative of events that took place during the life of Jesus and his followers. 2. Acts: This book is also known as "Acts of Christ," but it was not written down until centuries later. It is believed to contain records from the period immediately following Jesus' death, including the death of Jesus himself, resurrection of Lazarus, crucifixion, burial, and death. 3. John: John the Baptist's letter to his followers contains instructions for the preparation for the coming of Christ, as well as messages about how to live a life of piety and obedience. 4. Hebrews: This book contains instructions for Christians on how to live their lives as they should be, based on Jesus' teachings. The New Testament is considered by many to be one of the most important sources in Christianity for understanding its history, beliefs, and practices.
