Why did Peter say Acts 10:28?
What historical context led to Peter's statement in Acts 10:28?

Acts 10:28

“You know how unlawful it is for a Jew to associate with or visit a foreigner. But God has shown me that I should not call any man impure or unclean.”


Covenant Separation in the Mosaic Law

Leviticus 20:24–26; Deuteronomy 7:1–6 and 14:2 teach that Israel was to remain a holy people, distinct from the nations. Dietary rules (Leviticus 11), circumcision (Genesis 17:10-14), and ritual purity codes created daily reminders of that distinction. Although the Torah does not forbid all contact with Gentiles, it clearly makes such contact socially and ceremonially difficult, fostering a centuries-long culture of separation.


Second-Temple Interpretations and Rabbinic Halakhah

By the first century AD, oral tradition had amplified biblical commands. The Mishnah (compiled later but reflecting earlier custom) records warnings against entering Gentile homes lest one become unclean (m. Oholot 18:7; m. Toharot 7:3). Josephus notes that strict Pharisees avoided dining with non-Jews (Antiquities 15.3.1). These unwritten halakhic fences, rather than the written Torah itself, are what Peter calls “our law.”


Archaeological Confirmation of Separation

Two Greek “soreg” inscriptions recovered near the Temple Mount (discovered 1871 and 1936) read: “No foreigner is to enter within the balustrade and embankment surrounding the sanctuary….” Violators faced death. Paul alludes to this literal wall in Ephesians 2:14. The physical barrier illustrates the social and ritual divide confronting first-century Jews like Peter.


Rome’s Occupation and the Rise of God-Fearers

Under Roman rule (63 BC–AD 70) large Jewish communities lived amid Gentile cities. Many Gentiles, attracted by monotheism and synagogue ethics, became “God-fearers” (cf. Acts 10:2, 13:43). Yet full conversion required circumcision, so most remained outsiders—a tension Luke underscores by introducing Cornelius, a Roman centurion who worshiped Israel’s God but was still regarded as unclean by strict Jews.


Peter’s Background and Galilean Jewish Piety

Raised in Bethsaida/Capernaum, Peter would have absorbed Pharisaic norms (Mark 7:3-4). Even after Pentecost, Acts 10 occurs roughly a decade into the church’s life (c. AD 40). The apostolic community still gathered at the Jerusalem Temple (Acts 2:46; 3:1) and had not yet questioned the Jewish-Gentile divide.


The Twin Visions: Cornelius and Joppa

Cornelius (at Caesarea Maritima) receives angelic instruction to fetch Peter (Acts 10:3-6). The next day, atop Simon the tanner’s house in Joppa, Peter sees a sheet with “all kinds of four-footed animals…reptiles…and birds” (10:12). Three divine commands to “Kill and eat” confront his conscience formed by Leviticus 11. Peter’s triple refusal—“Surely not, Lord!”—mirrors his three earlier denials and threefold restoration (John 18; 21), emphasizing transformation.


Immediate Cultural Catalyst for the Statement

While Peter ponders the vision, Cornelius’s emissaries arrive (Acts 10:17-23). The Spirit tells him to go “without hesitation” (10:20). The next day, Peter enters Cornelius’s Gentile residence—an unprecedented act for a devout Jew. Standing inside, he utters Acts 10:28. Thus the statement springs from:

1. Long-standing Jewish purity customs,

2. Additional rabbinic prohibitions,

3. A fresh, authoritative revelation from God overturning those customs, and

4. A providential encounter orchestrated by simultaneous visions.


Prophetic Foundations for Gentile Inclusion

Peter’s change of heart fulfills earlier Scripture:

Genesis 12:3—“all families of the earth will be blessed.”

Isaiah 49:6—“I will also make You a light for the nations.”

Zechariah 2:11—“Many nations will join themselves to the LORD.”

The consistency of God’s salvific intent counters any claim of contradiction between Old and New Testament.


Apostolic and Petrine Authority

Peter, holder of the “keys of the kingdom” (Matthew 16:19), now unlocks the gospel to Gentiles. Later he defends this action before the Jerusalem church (Acts 11:1-18), and the Spirit’s visible descent on Cornelius’s household (10:44-48) becomes irrefutable evidence.


Theological Ramifications

Acts 10:28 marks the hinge of salvation history:

• Abolishing ceremonial barriers (Ephesians 2:14-16).

• Declaring all foods—and by extension, all peoples—clean (Mark 7:19).

• Anticipating the Jerusalem Council’s verdict (Acts 15:7-11).

• Affirming that righteousness comes by faith, not lineage or law (Romans 3:29-30).


Practical Application for Modern Readers

Believers must:

1. Reject ethnic, cultural, or class prejudice.

2. Trust God’s Word over entrenched tradition.

3. Recognize the Spirit’s leading even when it challenges comfort zones.

4. Proclaim salvation through Christ to every nation, confident that Scripture, history, and reason harmonize in supporting the gospel’s universal reach.


Conclusion

Peter’s declaration in Acts 10:28 arose from centuries of divinely instituted but time-bound rituals, later fenced by human custom, now superseded by direct revelation culminating in the crucified and risen Messiah. Historical records, archaeological artifacts, and the unbroken manuscript chain all converge to affirm Luke’s report and the gospel’s unstoppable expansion “to the ends of the earth” (Acts 1:8).
