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 often raises the question of authorship, and it's a fascinating topic filled with scholarly debate and cultural history! While Matthew the apostle has long been credited as the author, the reality could be more nuanced. Some scholars argue that the writer likely drew from the earlier Gospel of Mark, alongside other sources - including the so-called "Q" source, which is believed to have contained many sayings of Jesus.

What’s particularly interesting is the context in which Matthew was written. This Gospel primarily caters to a Jewish audience, highlighting Jesus as the fulfillment of the Hebrew Scriptures. It includes numerous references to Isaiah and other prophetic books, showing how Jesus embodies the coming Messiah that numerous Jewish writings anticipate.

There’s also a remarkable echo of the Old Testament throughout Matthew, which pulls key events from Israel’s history and parallels them with Jesus' life. For instance, you see echoes of Moses—just as the Israelites fled Egypt, so did Mary and Joseph take baby Jesus to escape King Herod.

And here’s a fun tidbit: Matthew is known for its unique features, like the detailed genealogy that spans back to Abraham, emphasizing the Jewish heritage of Jesus. So, whether the traditional authorship stands or not, Matthew’s Gospel certainly provides compelling insight into the early Christian understanding of Jesus’ identity.
