My Preface:
- Below are responses from ChatGPT and ClaudeAI to the same request. The most important point, IMHO, that both make of evidence of perhaps the entire verses Mat 16:17-19 as an interpolation is that Jesus says he will build a church (‘ekklesia’) when he was a devoted Jew attending Synagogue. Therefore, the text was added when the institutional church, separate from Jewish traditions, was developing. The are other plausible reasons (one relates to leadership) for it being an interpolation. Scroll to the bottom of this page for the red text under the heading “Key arguments for interpolation:“.
- Also see the post at this site here about Jesus’ one-time use of the nickname “Peter” after he supposedly renamed Simon. In seven (7) other places, he addresses Simon as Simon.
- Of course, it could have been in the original text of the book, later named Matthew, and is the author’s literary creation to elevate Simon’s role in the 80’s CE when the Jesus sect of Judaism was growing under James’ leadership.
From ChatGPT in response to the prompt: Have any critical bible scholars suggested that the verse in Matthew 16 that includes “and on this rock I will build my church.” is an interpolation to raise Peter’s status above that of James the brother of Jesus?
Yes — several critical (historical-critical) scholars have suggested that Matthew 16:18–19, especially the phrase “you are Peter, and on this rock I will build my church” and the following “keys of the kingdom” statement, may be a later editorial addition or theological expansion designed to elevate Peter’s authority — possibly in contrast to the later prominence of James, the brother of Jesus, in the Jerusalem church.
Here’s a concise, source-cited summary of that view and who holds it:
1. The Key Passage
Matthew 16:17–19 (NRSV):
“Blessed are you, Simon son of Jonah! … And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it. I will give you the keys of the kingdom of heaven…”
This text has no parallel in Mark 8:29–30 or Luke 9:20–21, which both contain Peter’s confession but omit the “on this rock…” declaration.
2. Critical Scholarly Observations
(a) Raymond E. Brown (The Birth of the Messiah, 1993; Peter in the New Testament, 1973)
Brown noted that Matthew’s addition of the “rock” and “keys” passage likely reflects the post-Easter church’s theological reflection rather than the historical Jesus’ words.
He wrote that this passage “represents a later ecclesiastical interpretation of Peter’s role” rather than an original saying of Jesus. (Brown, Peter in the New Testament, jointly authored with Fitzmyer and Murphy, p. 92–94).
Brown did not use the word “interpolation” but acknowledged it as a Matthean composition expressing the church’s later hierarchy.
(b) John P. Meier (A Marginal Jew, vol. 3, 2001, pp. 164–172)
Meier accepts that Jesus may have given Simon the nickname Kephas, but the “I will build my church” saying “belongs to Matthew’s theological redaction.” He notes that Matthew’s version “reflects a time when Peter’s leadership was being theologically asserted,” especially against competing claims (e.g., those of James in Jerusalem or Paul elsewhere).
(c) Bart D. Ehrman (Jesus: Apocalyptic Prophet of the New Millennium, 1999, pp. 233–234)
Ehrman argues that the “rock” and “church” language reflect a later stage of ecclesial development, long after Jesus’ lifetime, when the institutional church was forming.
He writes that “the reference to the church (‘ekklesia’) places the saying firmly in the post-resurrection period, probably reflecting a time when Peter’s primacy was being emphasized in opposition to others, such as James.”
(d) Geza Vermes (The Authentic Gospel of Jesus, 2003, p. 307)
Vermes calls Matthew 16:18–19 “a piece of ecclesiastical propaganda” reflecting the developing authority structure of the Christian community.
He contrasts this with the historical Jesus, who did not found or mention an institutional “church.”
Vermes specifically ties the verse’s theological emphasis to later church politics, which included elevating Peter over James, who led the Jerusalem community (as described in Acts 15 and Galatians 1–2).
(e) Robert Funk and the Jesus Seminar (The Five Gospels, 1993, pp. 138–139)
The Seminar judged the “on this rock I will build my church” saying as non-authentic (“black” vote), describing it as “a saying created by the early church to support Peter’s authority” and having no connection to Jesus himself.
3. Historical Context for the Hypothesis
- James the brother of Jesus was recognized in early Jerusalem as the community’s leader (Acts 15:13; Galatians 1:19; 2:9,12).
- Peter, though prominent, moved among different regions and was not head of the Jerusalem church.
- Later Gentile churches, especially those influenced by Matthew’s community (probably in Syria), seem to have theologically elevated Peter as the foundational apostle.
- Thus, many scholars see Matthew 16:18–19 as a literary-theological interpolation or redaction that mirrors this shift from James-centered to Peter-centered authority.
4. Summary
| Scholar | View on Matthew 16:18–19 | Relation to Peter vs. James |
|---|---|---|
| Raymond Brown | Later Matthean composition, not a historical saying | Expresses Peter’s primacy in church theology |
| John Meier | Redactional addition by Matthew | Reflects growing claim of Peter’s leadership |
| Bart Ehrman | Post-Easter creation reflecting church hierarchy | Possibly to counter James’ authority |
| Geza Vermes | “Ecclesiastical propaganda” | Supports Peter over James |
| Jesus Seminar | Non-authentic, later creation | Invented to justify Peter’s prominence |
In summary:
Yes. Several critical scholars — including Brown, Meier, Ehrman, Vermes, and the Jesus Seminar — hold that Matthew 16:18–19 is a later ecclesiastical or redactional addition, not an authentic saying of Jesus.
They interpret it as a theological device to elevate Peter’s authority, possibly in contrast to James, who historically led the early Jerusalem movement.
Claude’s Response to the same Prompt.
Yes, several critical biblical scholars have indeed suggested that Matthew 16:18-19 (the “upon this rock I will build my church” passage) is a later interpolation or addition to the Gospel. Here are the main scholarly arguments:
Scholars who have questioned the authenticity:
- Rudolf Bultmann – One of the most influential New Testament scholars of the 20th century, argued that this passage was likely a post-resurrection saying that was placed back into the narrative of Jesus’s earthly ministry by the early church.
- Adolf von Harnack – Suggested these verses were later additions to Matthew’s Gospel.
- Other form critics – Many scholars in the form-critical tradition have questioned whether these verses go back to the historical Jesus.
Key arguments for interpolation:
- Absence in Mark and Luke: This saying appears only in Matthew, not in the parallel accounts in Mark 8:27-30 and Luke 9:18-21, which is suspicious for such an important declaration.
- Ecclesiastical language: The term “church” (ekklesia) appears only here and in Matthew 18:17 in all the Gospels, suggesting later church concerns rather than Jesus’s own vocabulary.
- Peter’s later role: Some scholars note that if Jesus had given Peter such clear authority, it’s odd that Paul and James (the brother of Jesus) appear to have equal or greater authority in the early Jerusalem church (see Galatians 2, Acts 15).
Regarding James specifically:
Yes, some scholars have noted the tension between Matthew 16:18 and the actual leadership structure reflected in Acts and Paul’s letters, where James the brother of Jesus appears to be the leader of the Jerusalem church, not Peter. In Galatians 2:9, Paul refers to James, Peter (Cephas), and John as “pillars,” but James is listed first. This has led some scholars to suggest that Matthew 16:18 may represent a Petrine community’s attempt to establish Peter’s primacy against competing claims, possibly including those of the Jerusalem church led by James.
Here’s a detailed context for Matthew 16:18 regarding the Greek wordplay of Πέτρος and πέτρα:
Verse (NRSV): “…you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it.”
Greek words:
- Πέτρος (Petros) — Peter, literally “stone” or “rock,” masculine form, used as Simon’s new name.
- πέτρα (petra) — “rock, large mass of rock,” feminine form, used in the phrase “on this rock.”
Wordplay:
- Jesus is making a linguistic distinction between Simon (Petros) and the foundational “rock” of the church (petra).
- In Koine Greek, masculine nouns often differ from feminine ones, so the text deliberately uses Petros ≠ petra grammatically, but maintains the semantic connection.
- In Aramaic, which Jesus likely spoke, both words would have been Kepha (כֵּיפָא), removing the gender distinction; the pun is preserved: Simon is “Rock.”
Context in the passage:
- Matthew 16:13–20 describes Peter’s confession: “You are the Messiah, the Son of the living God.”
- Jesus responds to Peter personally, then expands the meaning to a broader foundation for the community (church).
- The “rock” may refer to:
- Peter himself (his confession and leadership role).
- The confession of faith (“You are the Messiah”).
- Christ himself as the spiritual foundation (less common in Greek-centered readings).
Critical scholarship notes:
- Many scholars (e.g., Davies & Allison, Luz, Nolland) emphasize the Greek wordplay preserves the Aramaic pun but introduces subtle distinctions for the Greek reader.
- Denominational differences arise:
- Roman Catholic interpretation: Peter himself is the rock; the passage supports apostolic succession.
- Protestant interpretation: The confession or Christ himself is the “rock”; Peter is not personally the foundation.
- Most scholars agree that the Greek deliberately contrasts the proper noun (Petros) with the common noun (petra) while maintaining the pun’s meaning.
Summary of why preachers vary:
- Greek literalists often note the gendered distinction and the linguistic pun.
- Sermons sometimes overextend the Greek to argue denominational points.
- Others minimize it, treating “Peter = rock” as a straightforward name-change story, missing the textual nuance.
