Corinth

Paul's 18-month mission base and the city to which he wrote 1–2 Corinthians; excavated finds including the Erastus Inscription and Gallio Inscription anchor Pauline chronology.

Ancient Corinth occupied one of the most strategically valuable locations in the ancient Mediterranean world. Sitting on a narrow strip of land between the Saronic Gulf to the east and the Gulf of Corinth to the west, the city controlled overland traffic between mainland Greece and the Peloponnese. Ships heading from Rome to the Aegean Sea could avoid the dangerous voyage around the southern tip of Greece by crossing the isthmus at Corinth. Goods were dragged across on a stone track called the diolkos. This geography made Corinth one of the wealthiest cities in the Roman Empire.

The American School of Classical Studies at Athens began formal excavations at Corinth in 1896 and has continued working at the site for well over a century, making it one of the longest-running archaeological projects in the Greek world. The team has excavated large portions of the Roman city's center, uncovering the agora (public square), temples, fountains, shops, and roads.

The city Paul knew was not the classical Greek Corinth but a Roman colonial refounding. The Roman general Mummius destroyed the Greek city in 146 BCE. Julius Caesar reestablished it as a Roman colony in 44 BCE, and within a generation it had grown into the capital of the Roman province of Achaia. By Paul's arrival around 51 CE, Roman Corinth was a busy, multilingual port city filled with merchants, freedmen, veterans, and migrants from across the empire.

The most important physical space for understanding Paul's time in Corinth is the bema, a large raised stone platform in the center of the agora. The bema served as the official judgment seat where the Roman proconsul heard legal cases. Acts 18:12 says that when Gallio was proconsul of Achaia, the Jewish community dragged Paul before this very platform and accused him of illegal religious teaching. Gallio dismissed the case, saying it was an internal Jewish dispute. The excavated bema is a large rectangular structure with steps leading up to a raised platform, consistent with its function as a place of public address and legal proceedings.

The Gallio Inscription, found at Delphi rather than Corinth, is a Greek stone inscription that records a letter from the emperor Claudius to the city of Delphi. It mentions Gallio as proconsul of Achaia and dates to around 51 or 52 CE. Because Acts 18:11–12 places Paul's 18-month stay in Corinth during Gallio's tenure, the inscription serves as one of the most precise chronological anchors in all of New Testament scholarship.

The Erastus Inscription, found in Corinth itself in 1929, is a Latin text cut into a large stone paving block near the theater. It reads: 'Erastus, in return for his aedileship, laid (this pavement) at his own expense.' An aedile was a city official responsible for public buildings and infrastructure. Romans 16:23, written by Paul from Corinth, sends greetings from 'Erastus, the city treasurer.' Whether the inscription and the biblical Erastus are the same person is debated, but the name and municipal role make the connection plausible and widely discussed.

A limestone lintel block found near the eastern end of the Lechaion Road bears a Greek inscription that has been partially reconstructed to read 'Synagogue of the Hebrews.' The block dates to the late Roman period and likely came from a synagogue that stood near the city's main north-south road. Acts 18:4 says Paul reasoned in the synagogue every Sabbath during his time in Corinth. Though this inscription probably postdates Paul's visit by at least a century, it confirms a Jewish presence along the main road into the city.

The Lechaion Road itself, a wide colonnaded street leading from the city center north toward the port, has been extensively excavated. Along its sides stood rows of shops, many of which Paul and his tentmaking colleagues Aquila and Priscilla might have occupied. The road is paved with limestone slabs and bordered by drainage channels, giving a strong impression of the busy commercial thoroughfare Paul would have walked regularly.

Seven temples from the Greek and Roman periods have been identified in the excavated area. The most visible today is the Temple of Apollo, whose 7 surviving Doric columns predate Paul's visit by six centuries. The Corinthian agora also contained the fountain of Peirene, a famous spring fed by an underground reservoir, as well as administrative buildings and honorary monuments.

The Archaeological Museum of Ancient Corinth, located adjacent to the site, holds thousands of objects from the excavations including pottery, sculpture, glass, inscriptions, and bronze work. The museum provides essential context for understanding the city's long occupation from prehistoric times through the Byzantine period.

• The bema, a large stone platform in the agora, is the excavated judgment seat where Paul appeared before the proconsul Gallio as described in Acts 18:12
• The Erastus Inscription, a Latin paving stone dedication near the theater, names a city aedile whose role and name match the Erastus mentioned in Romans 16:23
• A limestone block bearing a partial Greek inscription reading 'Synagogue of the Hebrews' was found near the Lechaion Road, confirming a Jewish community presence
• The Gallio Inscription from Delphi (not Corinth itself) names Gallio as proconsul of Achaia during Claudius's reign, dating Paul's Corinthian stay to approximately 51–52 CE
• The Lechaion Road, a colonnaded commercial street, was lined with shops consistent with the artisan district where Paul, Aquila, and Priscilla worked as tentmakers (Acts 18:3)
• Seven temple foundations have been identified in the agora area, illustrating the city's polytheistic religious environment that Paul addressed in 1 Corinthians
• The Temple of Apollo, with 7 surviving Doric columns, is the oldest visible structure on the site, predating the Roman colonial refounding by centuries
• Excavations have continued for over 125 years, making Corinth one of the most thoroughly documented Roman provincial cities in the Mediterranean

Corinth is woven through the New Testament in ways that few other cities can match. Acts 18:1 introduces Corinth as the city Paul entered after leaving Athens, and verse 11 specifies that he stayed there a year and six months, teaching the word of God. During this time he lived and worked with Aquila and Priscilla, fellow tentmakers who had been expelled from Rome (Acts 18:2–3). First Corinthians 1:2 and 2 Corinthians 1:1 are both addressed to 'the church of God that is in Corinth.' The moral problems Paul addresses in 1 Corinthians, including lawsuits among believers, sexual immorality, food offered to idols, and divisions at the Lord's Supper, all reflect the social complexity of a port city where many cultures and religions overlapped. The temples and marketplaces excavated at Corinth provide the physical setting for these disputes. Acts 18:12–17 describes the incident before Gallio's bema, the physical platform now excavated in the agora. Paul was accused by the Jewish community, but Gallio refused to hear the case, setting a legal precedent that Roman courts would not adjudicate internal Jewish religious disputes. This episode protected Paul's mission in Corinth. Romans 16:23 was likely written from Corinth during Paul's third visit and includes greetings from Erastus, 'the city treasurer,' a detail that resonates with the Erastus Inscription found near the theater. First Corinthians 8 and 10 address eating food sacrificed to idols, a daily practical question in a city filled with temple precincts, meat markets connected to sacrifices, and dinner invitations from pagan hosts. The excavated temples and commercial districts make this not an abstract theological question but a real challenge of urban life in Roman Corinth.
