The Gospel of Luke tells of the origins, birth, ministry, death, resurrection, and ascension of Jesus Christ. Together with the Acts of the Apostles, it makes up a two-volume work which scholars call Luke–Acts, accounting for 27.5% of the New Testament. The combined work divides the history of first-century Christianity into three stages, with the gospel making up the first two of these – the life of Jesus the Messiah from his birth to the beginning of his mission in the meeting with John the Baptist, followed by his ministry with events such as the Sermon on the Plain and its Beatitudes, and his Passion, death, and resurrection.
Most modern scholars agree that the main sources used for Luke were a), the Gospel of Mark, b), a hypothetical sayings collection called the Q source, and c), material found in no other gospels, often referred to as the L (for Luke) source. The author is anonymous; the traditional view that Luke the Evangelist was the companion of Paul is still occasionally put forward, but the scholarly consensus emphasises the many contradictions between Acts and the authentic Pauline letters. The most probable date for its composition is around AD 80–110, and there is evidence that it was still being revised well into the 2nd century.
Acts of the Apostles#Manuscripts
Autographs (original copies) of Luke and the other Gospels have not been preserved; the texts that survive are third-generation copies, with no two completely identical. The earliest witnesses (the technical term for written manuscripts) for the Gospel of Luke fall into two "families" with considerable differences between them, the Western and the Alexandrian text-type, and the dominant view is that the Western text represents a process of deliberate revision, as the variations seem to form specific patterns.
The fragment is often cited as the oldest witness. It has been dated from the late 2nd century, although this dating is disputed. Papyrus 75 (= Papyrus Bodmer XIV–XV) is another very early manuscript (late 2nd/early 3rd century), and it includes an attribution of the Gospel to Luke.
