The New Testament (NT) is the second division of the Christian biblical canon. It discusses the teachings and person of Jesus, as well as events relating to first-century Christianity. The New Testament's background, the first division of the Christian Bible, has the name of Old Testament, which is based primarily upon the Hebrew Bible; together they are regarded as Sacred Scripture by Christians.
The New Testament is a collection of 27 Christian texts written in Koine Greek by various authors. It includes four gospels, the Acts of the Apostles, epistles attributed to Paul and other authors, and the Book of Revelation. The New Testament canon developed gradually over the first few centuries of Christianity through a complex process of debate, rejection of heretical texts, and recognition of writings deemed apostolic, culminating in the formalization of the 27-book canon by the late 4th century. It has been widely accepted across Christian traditions since Late Antiquity.
Literary analysis suggests many of its texts were written in the mid-to-late first century. There is no scholarly consensus on the date of composition of the latest New Testament text. The earliest surviving New Testament manuscripts date from the late second to early third centuries AD, with the possible exception of Papyrus 52.

The New Testament was transmitted through thousands of manuscripts in various languages and church quotations and contains variants. Textual criticism uses surviving manuscripts to reconstruct the oldest version feasible and to chart the history of the written tradition. It has varied reception among Christians today. It is viewed as a holy scripture alongside Sacred Tradition among Catholics and Orthodox, while evangelicals and some other Protestants view it as the inspired word of God without tradition.
Etymology
The word testament
The word testament in the expression "New Testament" refers to a Christian new covenant that Christians believe completes or fulfils the Mosaic covenant (the Jewish covenant) that Yahweh (the God of Israel) made with the people of Israel on Mount Sinai through Moses, described in the books of the Old Testament of the Christian Bible. While Christianity traditionally even claims this Christian new covenant as being prophesied in the Jewish Bible's Book of Jeremiah, Judaism traditionally disagrees:
Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah; not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; forasmuch as they broke My covenant, although I was a lord over them, saith the LORD. But this is the covenant that I will make with the house of Israel after those days, saith the LORD, I will put My law in their inward parts, and in their heart will I write it; and I will be their God, and they shall be My people; and they shall teach no more every man his neighbour, and every man his brother, saying: 'Know the LORD'; for they shall all know Me, from the least of them unto the greatest of them, saith the LORD; for I will forgive their iniquity, and their sin will I remember no more.

The word covenant means 'agreement' (from Latin convenio 'to agree', literally 'to come together'): the use of the word testament, which describes the different idea of written instructions for inheritance after death, to refer to the covenant with Israel in the Old Testament, is foreign to the original Hebrew word brit (בְּרִית) describing it, which only means 'alliance, covenant, pact' and never 'inheritance instructions after death'. This use comes from the transcription of Latin testamentum 'will (left after death)', a literal translation of Greek diathēkē (διαθήκη) 'will (left after death)', which is the word used to translate Hebrew brit in the Septuagint.
The choice of this word diatheke, by the Jewish translators of the Septuagint in Alexandria in the 3rd and 2nd century BC, has been understood in Christian theology to imply a reinterpreted view of the Old Testament covenant with Israel as possessing characteristics of a 'will left after death' (the death of Jesus) and has generated considerable attention from biblical scholars and theologians: in contrast to the Jewish usage where brit was the usual Hebrew word used to refer to pacts, alliances and covenants in general, like a common pact between two individuals, and to the one between God and Israel in particular, in the Greek world diatheke was virtually never used to refer to an alliance or covenant (one exception is noted in a passage from Aristophanes) and referred instead to a will left after the death of a person. There is scholarly debate as to the reason why the translators of the Septuagint chose the term diatheke to translate Hebrew brit, instead of another Greek word generally used to refer to an alliance or covenant.
The phrase New Testament as the collection of scriptures
The use of the phrase New Testament (Koine Greek: Ἡ Καινὴ Διαθήκη, Hē Kainḕ Diathḗkē) to describe a collection of first- and second-century Christian Greek scriptures can be traced back to Tertullian in his work Against Praxeas. Irenaeus uses the phrase New Testament several times, but does not use it in reference to any written text. In Against Marcion, written c. 208 AD, Tertullian writes of:

the Divine Word, who is doubly edged with the two testaments of the law and the gospel.
And Tertullian continues later in the book, writing:
it is certain that the whole aim at which he [Marcion] has strenuously laboured, even in the drawing up of his Antitheses, centres in this, that he may establish a diversity between the Old and the New Testaments, so that his own Christ may be separate from the Creator, as belonging to this rival God, and as alien from the law and the prophets.
By the 4th century, the existence—even if not the exact contents—of both an Old and New Testament had been established. Lactantius, a 3rd–4th century Christian author wrote in his early-4th-century Latin Institutiones Divinae (Divine Institutes):
But all scripture is divided into two Testaments. That which preceded the advent and passion of Christ—that is, the law and the prophets—is called the Old; but those things which were written after His resurrection are named the New Testament. The Jews make use of the Old, we of the New: but yet they are not discordant, for the New is the fulfilling of the Old, and in both there is the same testator, even Christ, who, having suffered death for us, made us heirs of His everlasting kingdom, the people of the Jews being deprived and disinherited. As the prophet Jeremiah testifies when he speaks such things: "Behold, the days come, saith the Lord, that I will make a new testament to the house of Israel and the house of Judah, not according to the testament which I made to their fathers, in the day that I took them by the hand to bring them out of the land of Egypt; for they continued not in my testament, and I disregarded them, saith the Lord." ... For that which He said above, that He would make a new testament to the house of Judah, shows that the old testament which was given by Moses was not perfect; but that which was to be given by Christ would be complete.
Eusebius describes the collection of Christian writings as "covenanted" (ἐνδιαθήκη) books in Hist. Eccl. 3.3.1–7; 3.25.3; 5.8.1; 6.25.1.
Books
The Gospels
Each of the four gospels in the New Testament narrates the life, death, and resurrection of Jesus of Nazareth (the gospel of Mark in the original text ends with the empty tomb and has no account of the post-resurrection appearances, but the emptiness of the tomb implies a resurrection). The word "gospel" derives from the Old English gōd-spell (rarely godspel), meaning "good news" or "glad tidings"; its Greek and Hebrew equivalents are euangélion (εὐαγγέλιον) and besorah (בְּשׂוֹרָה), respectively. The gospel was considered the "good news" of the coming Kingdom of God's own Messiah, and the redemption through the life and death of Jesus, the central Christian message.
Starting in the late second century, the four narrative accounts of the life and work of Jesus Christ have been referred to as "The Gospel of ..." or "The Gospel according to ..." followed by the name of the supposed author. The first author to explicitly name the canonical gospels is Irenaeus of Lyon, who promoted the four canonical gospels in his book Against Heresies, written around 180.
The Gospel of Matthew, ascribed to the Apostle Matthew. This gospel begins with a genealogy of Jesus and a story of his birth that includes a visit from magi and a flight into Egypt, and it ends with the commissioning of the disciples by the resurrected Jesus.

The Gospel of Mark, ascribed to Mark the Evangelist. This gospel begins with the preaching of John the Baptist and the baptism of Jesus and ends with the Ascension of Jesus.
The Gospel of Luke, ascribed to Luke the Evangelist, who was not one of the Twelve Apostles, but was mentioned as a companion of the Apostle Paul and as a physician.
The Gospel of John, ascribed to John the Evangelist. This gospel begins with a philosophical prologue and ends with appearances of the resurrected Jesus.
These four gospels that were eventually included in the New Testament were only a few among many other early Christian gospel traditions; the existence of such traditions, both written and oral, is even mentioned at the beginning of the Gospel of Luke. Various non-canonical gospels, such as the so-called "Jewish-Christian Gospels" and the Gospel of Thomas, were also written after the canonical gospels became widely known and used among early Christian communities, advocating for differing theological views, in particular Gnostic ones. In modern scholarship, the Synoptic Gospels are the primary sources for reconstructing Jesus Christ's ministry.
Acts of the Apostles
The Acts of the Apostles is a narrative of the apostles' ministry and activity after Jesus Christ's death and resurrection, from which point it resumes and functions as a sequel to the Gospel of Luke. Examining style, phraseology, and other evidence, modern scholarship generally concludes that Acts and the Gospel of Luke share the same author, referred to as Luke–Acts. Luke–Acts does not name its author. Church tradition identified him as Luke the Evangelist, the companion of Paul, but critical views at the end of the 20th century were evenly divided about whether Luke the physician wrote it due to the many differences between Acts and the authentic Pauline letters, though most scholars still believe the author, whether named Luke or not, met Paul. The most probable date of composition is around 80–90 AD, although some scholars date it significantly later. The earliest witnesses for Luke fall into the Western and the Alexandrian text-types and the dominant view is that the Western text represents a process of deliberate revision in the second century, as the variations seem to form specific patterns.
Epistles
Pauline letters to churches
The Pauline letters are the thirteen New Testament books that present Paul the Apostle as their author. Paul's authorship of six of the letters is disputed. Four are thought by most modern scholars to be pseudepigraphic, i.e., not actually written by Paul even if attributed to him within the letters themselves. Opinion is more divided on the other two disputed letters (2 Thessalonians and Colossians). These letters were written to Christian communities in specific cities or geographical regions, often to address issues faced by that particular community. Prominent themes include the relationship both to broader "pagan" society, to Judaism, and to other Christians.
Epistle to the Romans
First Epistle to the Corinthians
Second Epistle to the Corinthians
Epistle to the Galatians
Epistle to the Ephesians*
Epistle to the Philippians
Epistle to the Colossians*
First Epistle to the Thessalonians
Second Epistle to the Thessalonians*
[Disputed letters are marked with an asterisk (*).]
Pauline letters to persons
The last four Pauline letters in the New Testament are addressed to individual persons. They include the following:
First Epistle to Timothy*
Second Epistle to Timothy*
Epistle to Titus*
Epistle to Philemon
[Disputed letters are marked with an asterisk (*).]
All of the above except for Philemon are known as the Pastoral epistles. They are addressed to individuals charged with pastoral oversight of churches and discuss issues of Christian living, doctrine and leadership. They often address different concerns to those of the preceding epistles. These letters are believed by many to be pseudepigraphic. Some scholars (e.g., Bill Mounce, Ben Witherington, R.C. Sproul) will argue that the letters are genuinely Pauline, or at least written under Paul's supervision.
Hebrews
The Epistle to the Hebrews addresses a Jewish audience who had come to believe that Jesus was the Anointed One (Hebrew: מָשִׁיחַ—transliterated in English as "Moshiach", or "Messiah"; Greek: Χριστός—transliterated in English as "Christos", for "Christ") who was predicted in the writings of the Hebrew Scriptures. The author discusses the superiority of the new covenant and the ministry of Jesus, to the Mosaic Law Covenant and urges the readers in the practical implications of this conviction through the end of the epistle.
The book has been widely accepted by the Christian church as inspired by God and thus authoritative, despite the acknowledgment of uncertainties about who its human author was. Regarding authorship, although the Epistle to the Hebrews does not internally claim to have been written by the Apostle Paul, some similarities in wordings to some of the Pauline Epistles have been noted and inferred. In antiquity, some began to ascribe it to Paul in an attempt to provide the anonymous work an explicit apostolic pedigree.
In the 4th century, Jerome and Augustine of Hippo supported Paul's authorship. The Church largely agreed to include Hebrews as the fourteenth letter of Paul, and affirmed this authorship until the Reformation. The letter to the Hebrews had difficulty in being accepted as part of the Christian canon because of its anonymity. As early as the 3rd century, Origen wrote of the letter, "Men of old have handed it down as Paul's, but who wrote the Epistle God only knows."
Contemporary scholars often reject Pauline authorship for the epistle to the Hebrews, based on its distinctive style and theology, which are considered to set it apart from Paul's writings.
Catholic epistles
The Catholic epistles (or "General epistles") consist of both letters and treatises in the form of letters written to the church at large. The term "catholic" (Greek: καθολική, katholikē), used to describe these letters in the oldest manuscripts containing them, here simply means "general" or "universal" and does not refer to their canonical status among Christian traditions. The authorship of a number of these is disputed.
Epistle of James, written by an author named "James", often identified with James, the brother of Jesus.
First Epistle of Peter, ascribed to the Apostle Peter.
Second Epistle of Peter, ascribed to the Apostle Peter, though widely considered not to have been written by him.
