The second half of the Bible was written in Koine Greek after Christ's ascension by various authors before the close of the first century. The authors either knew Christ personally, were mentored by those who were His disciples, or had personal a encounter with Him. The Greek Cannon has traditionally been known as the New Covenant or New Testament (Καινή Διαθήκη ľkainē diathēkē).
The original texts were written in Koine Greek (Κοινὴ Ἑλληνική), or common Greek. By the middle of the second century, most Christians had accepted a collection of books proposed by the Bishop of Alexandria in 367 AD just as we know them today. In 393 AD, the African Synod of Hippo approved the proposed list. The New Testament has traditionally been divided into four sections: the Gospels, the Acts of the Apostles, the Epistles, and the book of Revelation.
1. The Gospels is collection of four books that narrate the ministry of Jesus of Nazareth. The first three books are commonly known as the Synoptic Gospels. They contain very similar accounts of events in Jesus' life from the unique perspective of the authors. The Gospel of John, unlike the first three, records several miracles and sayings of Jesus, not found elsewhere.
Matthew, Mark, Luke, and John
2. The Acts of the Apostles (or Acts of the Holy Spirit) is a narrative of the Apostles' ministry after Christ's death, and a sequel to the Gospel of Luke.
3. The Epistles Pauline Epistles (or Corpus Paulinum), traditionally attributed to the apostle Paul
Romans, 1st and 2nd Corinthians, Galatians, Ephesians, Philippians, Colossians. 1st and 2nd Thessalonians, 1st and 2nd Timothy, Titus, Philemon, and Hebrews.
General or Catholic Epistles, written to the church at large; Catholic in this sense simply means universal.
James, 1st and 2nd Peter, 1st, 2nd, and 3rd John, Jude
4. The Book of Revelation (or Apocalypse of John) the is the final book of the New Testament. This last prophetic or apocalyptic book has had a profound impact on Christian theology for two millennia.
Order of the Books
The New Testament books are ordered differently depending on various Church traditions. Protestants have traditionally followed the Roman Catholic order (without the additional apocrypha collection). The traditional Lutheran order is different. The Slavonic, Syriac and Ethiopian Bibles differ from the traditional Catholic/Protestant order.
