* Matthew: Attributed to Matthew, a former tax collector who became one of Jesus' disciples.
* Mark: Attributed to Mark, a close companion of the apostle Peter.
* Luke: Attributed to Luke, a physician and close companion of the apostle Paul.
* John: Attributed to John, one of Jesus' twelve disciples.
However, it's important to note that:
* Scholarly debate exists: While these attributions are widely accepted within Christian tradition, modern biblical scholarship has raised questions about the traditional authorship of some Gospels.
* Possible authorship by others: Some scholars argue that the Gospels may have been written by individuals other than the traditional authors or that they may represent the work of multiple authors and editors.
* Focus on content: Regardless of authorship, the Gospels are considered important historical and theological texts within Christianity.
It's important to approach these questions with an open mind and to consult various resources and scholarly perspectives.
