The answer is: Matthew

Matthew 9:9 - Matthew, also known as Levi, left his lucrative tax collector position to follow Jesus, illustrating the transformative power of Christ’s call. His unique background enriches the Gospel with insights into societal outcasts. Interestingly, he emphasizes Jesus’ fulfilment of Old Testament prophecies, bridging Jesus' ministry with Jewish tradition.

Let's dig a little deeper into Matthew, the disciple whose story is as intriguing as his former job. Tax collectors in first-century Judea were often marginalized figures, seen as traders who collaborated with the oppressive Roman regime. This stigma is crucial because it frames Matthew's radical decision to leave behind a comfortable, albeit contentious, life for an uncertain path with a traveling teacher.

Matthew, or Levi, doesn’t just ditch his tax booth; he dives into a mission that transforms societal norms! In his Gospel, he often references back to the Old Testament, weaving a rich tapestry of Jewish culture into the story of Jesus. Did you know that over 60% of his Gospel contains references to the Hebrew scriptures? This has made Matthew’s account particularly appealing to Jewish readers, showing them how Jesus neatly fulfills messianic prophecies.

Another fascinating aspect is Matthew’s parables and teachings. Take, for example, the Parable of the Lost Sheep, where a shepherd goes out of his way for just one sheep. This beautifully echoes the message of inclusion, one that resonates deeply, especially considering that Matthew himself was regarded as a societal outsider.

Imagine for a moment the conversations happening around the dinner table during his time with Jesus. Tax collectors, fishermen, zealots—vendors of the unrefined and the refined clashing together. Through his actions, Jesus demonstrates that everyone is welcome in this and the CIT portal of broader redemption. Such are the intriguing discussions you’d find with Mr. Levi, a tax collector turned promoter of grace, right?!
