The answer is: Matthew

Some scholars think it was an unknown author, using the gospel of Mark and other sources as a basis for the gospel of Matthew.

The Gospel of Matthew is a fascinating text, offering a unique perspective within the New Testament. While tradition holds that Matthew, a former tax collector turned disciple, is its author, many scholars suggest a different narrative. They propose that the gospel we read today might have been composed by someone using Mark’s work and incorporating additional sources, known as "Q," along with their own experiences and reflections regarding the life and teachings of Jesus.

This idea isn't as far-fetched as it seems. In ancient times, many texts were compiled this way, where sources were combined to create narratives aimed at particular audiences. Matthew is particularly interesting due to its structure, emphasizing the fulfillment of Old Testament prophecies, linking Jesus closely with Jewish tradition. It's loaded with teachings, such as the Sermon on the Mount (chapters 5-7), which introduces higher moral expectations and places Jesus as a divine lawgiver akin to Moses.

Here's a fun trivia nugget: Matthew is the only gospel to explore Jesus' lineage all the way back to Abraham, illustrating his significance within the larger Jewish context. Also, this gospel includes more parables than any other, showcasing Jesus' wish to teach through relatable stories. This highlights popular teaching methods of the time, effectively helping ordinary people grasp profound concepts! So, whether authored by Matthew himself or a skilled follower wishing to distill an ethical narrative, the Gospel of Matthew stands out as a rich document in understanding early Christian thought.
