Shared ground
Peter’s response is triggered by what he “saw,” meaning the extraordinary catch that has just happened (vv. 8–9). He physically drops to Jesus’ knees and speaks as someone overwhelmed: “Depart from me … I am a sinful man, Lord” (v. 8). Luke then explains this is not random drama but a shared, witnessed shock: everyone with Peter is amazed, including his named partners James and John (vv. 9–10a).
Jesus answers Peter’s fear with reassurance (“Don’t be afraid”) and a new direction: “From now on you will catch men alive” (v. 10b). The scene ends with concrete follow-through: after getting the boats to land, “they left everything, and followed him” (v. 11). That last line signals a decisive change of allegiance and daily path, not merely a private spiritual moment.
Where interpretation differs
Some think Peter’s “Depart from me” is mainly a reverent, instinctive recoil—he senses he is unfit to be near Jesus (v. 8). Others read it more literally: Peter is asking Jesus to leave because fear and shame make proximity feel dangerous.
“Lord” (v. 8) can be heard as a respectful title for someone with authority, or as a deeper recognition of who Jesus is. The text itself shows Peter recognizing Jesus’ authority and reacting with moral unworthiness; it does not fully spell out how developed Peter’s understanding is at this point.
“Catch men alive” (v. 10b) is also read with different emphases. Some stress rescue (people being brought into life rather than lost). Others stress recruitment or capture language (a striking reversal: fishermen now “fish” for people), while still taking Jesus’ “Don’t be afraid” as setting a non-violent, life-giving frame.
Why the disagreement exists
Luke compresses a lot into short phrases that can carry more than one natural sense: “Depart from me,” “Lord,” and “catch … alive” have ranges of meaning. Also, v. 11’s “they” could refer narrowly to Peter, James, and John, or more broadly to the group present; Luke names the partners but does not list everyone who follows.
What this passage clearly contributes
Explicitly, it portrays a typical pattern in Luke: a powerful act by Jesus produces fear and awe, the person’s unworthiness comes to the surface, Jesus reassures, and then Jesus assigns a new role and calls for a new direction (vv. 8–11). It also shows that the call affects real economic and social life: boats, partnership, and a profitable catch are left behind (v. 11). The passage frames discipleship as relational attachment to Jesus (“followed him”) and as participation in Jesus’ mission described in people-focused terms (v. 10b; compare Luke 5:10).
