do christians know that the four gospels of Mark,john,luke and mathew are anonymous?

It's important to acknowledge that strictly speaking, the gospels are anonymous. But the uniform testimony of the early church was that Matthew, also known as Levi, the tax collector and one of the twelve disciples and one of the twelve disciples, was the author of the first gospel in the New Testament; that John Mark, a companion of Peter, was the author of the gospel we call Mark; and that Luke, known as Paul's beloved physician, wrote both the gospel of Luke and the Acts of the Apostles.

What specific evidence do I have that they are the authors of the gospels? The oldest and probably most significant testimony comes from the Papias, who in about A.D. 125 specifically affirmed that Mark had carefully and accurately recorded Peter's eyewitness observations. In fact, he said Mark 'made no mistake' and did not include 'any false statement.' And Papias said Matthew had persevered the teachings of Jesus as well. Then Irenaeus, writing about A.D. 180, confirmed the traditional authorship.

In fact, here are Irenaeus' words: "Matthew published his own Gospel among the Hebrews in their own tongue, when Peter and Paul were preaching the Gospel in Rome and founding the church there. After their departure, Mark, the disciple and interpreter of Peter, himself handed down to us in writing the substance of Peter's preaching. Luke, the follower of Paul, set down in a book the Gospel preached by his teacher. Then John, the disciple of the Lord, who also leaned on his breast, himself produced his Gospel while he was living at Ephesus in Asia." If we can have confidence that the gospels were written by the disciples Matthew and John, by Mark, the companion of Paul, and sort of a first-century journalist, we can be assured that the events they recorded are based on either direct or indirect eyewitness testimony.

There are no known competitors for the synoptics. Nobody would have had a motivation to lie by claiming these people wrote these gospels, when they really didn't. Remember, these were unlikely characters. Mark and Luke weren't even among the twelve disciples. Matthew was, but as a former hated tax collector, he would have been the most infamous character next to Judas Iscariot, who betrayed Jesus!

Contrast this with what happened when the fanciful apocryphal gospels were written much later. People chose heavy names well-known and exemplary figures to be their fictitious authors like Philip, Peter, Mary, James. Those names carried a lot more weight than the names Matthew, Mark, and Luke. There would not have been any reason to attribute authorship to these three less respected people if it weren't true.
