In truth, none of the writers of the four Gospels are specified. None of the writers ‘signed’ their writings. While the Gospels, themselves, do not actually say who wrote them, we do have these confirming ‘proofs’ to consider:

  1. The names of Matthew, Mark, Luke and John were linked with their Gospel accounts from the very earliest days.
  2. No other authors have ever been suggested for them.
  3. There are thousands of Greek manuscripts of the Gospels, and they all give them the same authors.

Of the four Gospels, only two were written by the original twelve apostles. Matthew and John were original apostles, but Mark and Luke were not. There is a good deal written in the book of Acts concerning Mark. He is sometimes referred to as John Mark and sometimes called Marcus. Mark, evidently was mentored greatly by the Apostle Peter. We read in 1 Peter 5:13, “The church that is at Babylon, elected together with you, saluteth you; and so doth Marcus my son.” Calling Marcus his son, indicates a close relationship, even as the Apostle Paul referred to Timothy and Titus as his sons.Luke was a doctor who travelled extensively with the Apostle Paul. Besides writing the Gospel of Luke, he also wrote the book of Acts. You’ll notice in Luke 1:3 and in Acts 1:1, that both of these books were addressed to a man named Theophilus. Acts 1:1 says, “The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach.” This ‘former treatise’, or account’ in all likelihood refers to the Gospel of Luke.There is no reason to doubt that the Gospels were not written by the men whose names are attached to them. However, most importantly, the Gospels were written by the Lord. 2 Timothy 3:16-17 assures us that, “All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.” No matter whose name is attached to these books, we can rest assured that the writers were inspired of God to write their books, and these books are profitable to us.
