Nevertheless, they did not inquire directly from Jesus about this matter; instead, they posed the question: "Why do the scribes say that Elijah must come first?"
It is essential to comprehend the full scope of the apostles' reflections on their experiences and on Christ's statements regarding His resurrection. Ultimately, they sought clarification on two key queries: what it signifies for the Son of Man to rise from the dead and why the scribes assert the necessity of Elijah’s prior arrival. Jesus indeed addressed both questions. Matthew clearly conveys His response, with the additional note that "then the disciples understood that He spoke to them of John the Baptist." This insight reframes Malachi's prophecy not as a future prediction but as a doctrinal assertion that exists outside the constraints of time.
The expression in Mark’s Gospel is somewhat complex; it’s important to recognize that Jesus provides answers to two questions, which are presented distinctly in Mark. First, He responds to their inquiry regarding Elijah’s arrival before the Messiah, affirming that Elijah must come beforehand to restore all things, as indicated in Malachi 4:5. Following this, He addresses a question the disciples did not articulate: what does it mean for the Son of Man to rise from the dead? Some scholars suggest that a question mark could follow the phrase "of the Son of Man," implying an inquiry into His mission. The answer encompasses His impending suffering and humiliation: He will endure great distress and be brought low. Ultimately, Christ revisits the initial question, stating that Malachi's prophecy concerning Elijah has already been fulfilled, and that this Elijah experienced similar trials to those He Himself was about to undergo. The scriptural references to this could likely be found within the historical narratives surrounding the prophet Elijah and the persecution he faced from King Ahab.
