Mark
Mark is the primary source for information about Jesus.[62] It was possibly composed in Rome[63] or Antiochine Southern Syria.[64]
Tradition holds that the Gospel of Mark was written by Mark the Evangelist, as St. Peter's interpreter.[67] Numerous early sources say that Mark's material was dictated to him by St. Peter, who later compiled it into his gospel.[70][71][72][73][74] The gospel, however, appears to rely on several underlying sources, which vary in form and in theology, and which tell against the story that the gospel was based on Peter's preaching.[75]
Most scholars believe that Mark was written by a second-generation Christian, around or shortly after the fall of Jerusalem and the destruction of the Second Temple in year 70.[76][77][78]
Luke
As is the case with all the Gospels, it is unknown exactly when the Gospel of Luke was written. Scholars have proposed a range of dates from as early as 60 AD to well into the second century, but the majority of recent critical scholars favour late 1st-century dates after 70 AD.[105][106][107][108]
It is generally agreed that the Gospel of Luke and the Acts of the Apostles were both written by the same author, and they are often referred to as a single work called Luke-Acts.[109] The most direct evidence comes from the prefaces of each book. Both prefaces were addressed to Theophilus, and Acts of the Apostles (1:1–2) says in reference to the Gospel of Luke, "In my former book, Theophilus, I wrote about all that Jesus began to do and teach until the day He was taken up to heaven, after giving instructions through the Holy Spirit to the apostles He had chosen." (NIV) Furthermore, there are linguistic and theological similarities between the two works, suggesting that they have a common author.[110][111] Both books also contain common interests.[112]
John
John was likely composed at Ephesus, although other possibilities are Antioch, Northern Syria,[97] Palestine and Alexandria.[113] Some scholars believe that Jesus' teaching in this gospel cannot be reconciled with that found in the synoptics,[114] whilst others, including John A.T. Robinson hold the view that the synoptics are best reconciled within the framework of John.[115]
In the majority viewpoint, it is unlikely that John the Apostle wrote the Gospel of John.[116][117] Rather than a plain account of Jesus' ministry, the gospel is a deeply mediated representation of Jesus' character and teachings, making direct apostolic authorship unlikely.[118] Opinion, however, is widely divided on this issue and there is no widespread consensus.[119][120] Many scholars believe that the "beloved disciple" is a person who heard and followed Jesus, and the gospel of John is based heavily on the witness of this "beloved disciple."[121]
