Analysis of the structure of Peter's defense before the Sanhedrin

Peter's answer — show definition INF336 before the Sanhedrin — show definition INF003 (Acts 4.8-12) is relatively short, but it has a very elaborate structure. It recalls both Peter's earlier speeches and certain methods of argument used by Jesus himself. It can be divided into five parts.

1. A respectful introduction (Acts 4.8)

Peter begins by addressing the members of the court with deference:

“Rulers of the people and elders of Israel” (Acts 4.8).

He does not challenge their authority and does not seek confrontation. Luke, moreover, specifies that Peter is “filled with the Holy Spirit,” thus underscoring that his answer fits within the fulfillment of Jesus' promises (Matthew 10.19-20; Luke 12.11-12).

2. A skillful rephrasing of the accusation (Acts 4.9)

The Sanhedrin — show definition INF003 had asked:

“By what power or in what name have you done this?” (Acts 4.7)

Peter turns this accusation into something almost paradoxical:

“If we are being examined today about a good deed done to a sick man…” (Acts 4.9).

In a few words, he puts his judges in an awkward position: this trial is actually about the healing of a disabled man. The argument recalls several of Jesus' answers, which often led his opponents to realize the absurdity of their position (Matthew 12.10-12; Luke 13.14-17).

3. The Christ-centered proclamation (Acts 4.10)

Peter answers the question directly:

“By the name of Jesus Christ of Nazareth…” (Acts 4.10).

Then he summarizes the whole work of salvation:

• Jesus of Nazareth;
• his crucifixion;
• the responsibility of the Jewish leaders;
• his resurrection;
• the miracle performed.

As in his earlier speeches (Acts 2.22-24; Acts 3.13-16), the resurrection of Christ holds a central place.

4. The scriptural argument (Acts 4.11)

Peter then quotes Psalms 118.22:

“The stone rejected by you builders has become the chief cornerstone” (Acts 4.11).

Here he takes up exactly the interpretation that Jesus himself had given of this text before these same authorities (Matthew 21.42). The argument is particularly powerful:

• the builders represent the religious leaders;
• the rejected stone is Jesus;
• God overturned their judgment by making this stone the cornerstone — show definition INF197.

Thus, Peter demonstrates that their rejection of the Messiah had been foretold in the Scriptures.

5. The conclusion: the universality and exclusivity of salvation (Acts 4.12)

The speech ends with a solemn declaration:

“There is salvation in no one else” (Acts 4.12).

Peter then widens the debate:

• it is no longer only about the healing of the lame man — show definition INF330;
• nor even about the trial of the apostles;
• but about the salvation of all humanity.

The progression of the reasoning is remarkable:

Healing of the lame man → Jesus crucified → Jesus risen → Fulfillment of the Scriptures → Universal salvation.

General structure

Conclusion

Peter's answer — show definition INF336 is built with great mastery. In a few verses, Peter:

1. respects his judges;
2. implicitly turns the accusation back against them;
3. proclaims Jesus crucified and risen;
4. relies on the Scriptures;
5. concludes with a solemn affirmation of the uniqueness of salvation.

This structure is very close to that of the speeches of Jesus reported in the Gospels. Peter thus appears as a true disciple who has become a teacher in his turn, reproducing, under the action of the Holy Spirit (Acts 4.8), the way of reasoning and bearing witness of his Lord.
