I have recently read articles and videos saying that no one knows who wrote the gospels - that there was no way Matthew, Mark, Luke and John could have written them. They even stated that they were not even written by eyewitnesses. They had a lot of info to back this up. Please tell me this is false.
This is false. Without knowing which articles you read and videos you saw, I can say that the content reflects the historical-critical method of biblical interpretation. That method rejects the verbal inspiration of the Bible. So, if people reject the truth that the Holy Spirit inspired Matthew, Mark, Luke and John to write the books of the Bible named after them, they have to come up with an alternative.
The alternative is a confused mess that allows “scholars” to pick and choose what they want to accept as being from God. The alternative theorizes that oral stories about Jesus developed first. Eventually, people put those stories into print. Finally, editors—in the second century A.D.—put the gospels in finished format.
The apostle Peter spoke for all the apostles when he wrote: “For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty. He received honor and glory from God the Father when the voice came to him from the Majestic Glory, saying, ‘This is my Son, whom I love; with him I am well pleased.’ We ourselves heard this voice that came from heaven when we were with him on the sacred mountain” (2 Peter 1:16-18).
