The authors of the four gospels

The Gospel Authors. Each of the four gospels was written by two authors. The main author is God Himself, who by the Holy Spirit, influenced what Matthew, Mark, Luke, and John wrote (2 Pet. 1:20-21). What they wrote were the sacred scriptures - God’s own words.

The human authors were Matthew, Mark, Luke, and John. The title of each gospel reads as “According to . . . “ That is, each gospel was according to the name that followed: Matthew, Mark, Luke, and John. Both Matthew and John were disciples of Jesus, or apostles. They lived with Jesus, heard Him teach, encouraged others, watched Him heal, and talked with Him one-on-one. They knew Jesus personally. The gospel of Matthew was written only 25-35 years after Jesus’ death.

Mark was a disciple of the Apostle Peter; he who wrote for Peter. Luke was a medical doctor (Col. 4:14) who had a passion for accuracy and detail. He was a companion of the Apostle Paul (2 Tim. 4:11; Philemon 1:24).
These are the men that the Holy Spirit used to write the historical records about Jesus Christ our God.

Other Accounts. The opening verses of the gospel by Luke capture one of the reasons why all of the four gospels were written.

Inasmuch as many have undertaken to compile an account of the things accomplished among us, (NASB) Luke 1:1

They understood what happened with Jesus and had a desire to record what really occurred for all of us. Other accounts about Jesus had also been written, but they were not accurate.

A group known as the Jesus Seminar has claimed that the Gospel of Thomas is a good source for information about Jesus. In fact, they have focused on that gospel and almost completely ignored Matthew, Mark, Luke, and John. Other gospels were also written. Some of them are the Gospel of Nicodemus, the Gospel of the nativity of Mary, the Gospel of Pseudo-Matthew, and the Arabic Gospel of the Infancy of Jesus. But all of these gospels were rejected by the apostles and subsequently by the early church.
