Paul's Third Missionary Journey (Acts 18:23–21:17)

The Third Missionary Journey (Acts 18:23–21:17) is the longest, most settled, and most consequential of the three great circuits recorded in the Acts of the Apostles. Spanning roughly five years, c. AD 52–57 (Scholarship), it carried Paul overland from Syrian Antioch across Cilicia — the province of his native Tarsus — up through the Cilician Gates and across the Anatolian plateau to Ephesus, where he remained longer than in any other city of his missionary career. From Ephesus the journey widened into a second circuit of Macedonia and Greece, a winter in Corinth, and a slow, deliberate return by sea along the coast of Asia Minor toward Jerusalem — a return Paul undertook knowing, as he told the elders of Ephesus at Miletus, that "bands and afflictions" awaited him (Acts 20:23) (Scripture).

The journey is also the great literary season of Paul's life: from Ephesus, Macedonia, and Corinth in these years came 1 and 2 Corinthians and the Epistle to the Romans — and, on one influential reading, Galatians as well (Scholarship, disputed).

Departure from Antioch: The Road Through Cilicia (c. AD 52–53)

Luke's notice of departure is brief: "And after he had spent some time there, he departed, and went through the country of Galatia and Phrygia, in order, confirming all the disciples" (Acts 18:23, Douay-Rheims) (Scripture). Behind that single sentence lies one of the great overland routes of the ancient world.

A traveller leaving Syrian Antioch for the Galatian and Phrygian interior went north and west by land: over the Syrian Gates in the Amanus range, around the head of the Gulf of Issus, and across the fertile Cilician plain — the plain commanded by Tarsus, metropolis of Roman Cilicia and Paul's birthplace (Acts 22:3) (Scripture). From the plain the road climbed to the one practicable breach in the Taurus mountains: the Cilician Gates, the narrow gorge (in modern Turkey, the Gülek pass) through which armies and caravans had funnelled for centuries. Acts does not name Tarsus on this journey, but the geography leaves little doubt that Paul crossed his home province and passed his home city, as he had done at the start of the second journey when he "went through Syria and Cilicia, confirming the churches" (Acts 15:41) (Scripture; the routing through the Gates is Scholarship, near-universally accepted).

For this library, that detail matters. The Third Journey opens where Paul's story is rooted: on the Roman road system of Cilicia, under the walls of Tarsus — the city of St. Paul's Well and Cleopatra's Gate — and up through the mountain gate that bound Cilicia to the plateau. Every westward journey of Paul's maturity begins, geographically, with Tarsus at its back.

Beyond the Gates, Paul revisited the churches of the interior "in order" — the natural reading takes him through the towns of the first journey's territory, Derbe, Lystra, Iconium, and Pisidian Antioch, and on through Phrygia (Scholarship). Luke then notes that Paul came to Ephesus "having passed through the upper coasts" (Acts 19:1, Douay-Rheims) — the higher inland road across the plateau rather than the lower valley highway, a small geographical touch that fits an author attentive to real itineraries (Scholarship).

The Ephesus Residency (Acts 19, c. AD 53–56)

Ephesus, on the Aegean coast of modern Turkey, was the effective capital of the Roman province of Asia: a harbour city, a banking centre, the seat of the proconsul, and the guardian of the temple of Artemis — one of the seven wonders of the ancient world. Paul had touched at Ephesus briefly at the end of the second journey and promised to return (Acts 18:19–21) (Scripture). He now made it his base for the better part of three years (Acts 20:31) (Scripture) — the longest recorded residency of his career.

Luke structures the Ephesian chapter in distinct movements:

The disciples of John (Acts 19:1–7). Paul found about twelve men who knew only the baptism of John; he instructed and baptized them, and they received the Holy Spirit (Scripture). Together with the account of Apollos, instructed at Ephesus just before Paul's arrival (Acts 18:24–28) (Scripture), the episode shows a movement still consolidating its boundaries.

Synagogue and school (Acts 19:8–10). Paul spoke boldly in the synagogue for three months; when opposition hardened, he withdrew the disciples and taught daily "in the school of one Tyrannus" (Acts 19:9, Douay-Rheims) (Scripture). This continued for two years, "so that all they who dwelt in Asia heard the word of the Lord, both Jews and Gentiles" (Acts 19:10) (Scripture). The lecture hall of Tyrannus — a hired schoolroom, on the common reading — marks a strategic shift: sustained, public, daily teaching in a metropolis whose commercial reach carried the message up the river valleys into the interior. It is widely held that the churches of the Lycus valley (Colossae, Laodicea, Hierapolis), and perhaps most of the "seven churches of Asia," were planted during this period by Paul's co-workers rather than by Paul in person (Scholarship).

Power and renunciation (Acts 19:11–20). Luke records extraordinary miracles, the humiliation of the seven sons of Sceva who attempted exorcism "by Jesus, whom Paul preacheth" (Acts 19:13) (Scripture), and a public burning of magical books valued at fifty thousand pieces of silver (Acts 19:19) (Scripture) — a dramatic collision with a city famous in antiquity for its written charms, the so-called "Ephesian letters" (Scholarship). Luke closes with a refrain: "So mightily grew the word of God, and was confirmed" (Acts 19:20, Douay-Rheims) (Scripture).

The Ephesian years were not tranquil. Paul later wrote of fighting "with beasts at Ephesus" (1 Corinthians 15:32) — almost certainly a metaphor for deadly opposition rather than the arena (Scholarship) — and of an affliction in Asia so severe that he despaired of life (2 Corinthians 1:8) (Scripture). Some scholars propose an otherwise unrecorded Ephesian imprisonment in these years (Scholarship, disputed).

The Riot of the Silversmiths (Acts 19:23–41)

Toward the end of the residency, opposition took economic form. Demetrius, a silversmith who made miniature silver shrines of Artemis (rendered "Diana" in older English versions), gathered the craftsmen and argued that Paul's preaching — "they are not gods which are made by hands" (Acts 19:26) (Scripture) — threatened both their trade and the honour of the goddess "whom all Asia and the world worshippeth" (Acts 19:27) (Scripture).

The result was a city in uproar. The crowd seized Gaius and Aristarchus, Paul's Macedonian companions, and rushed into the great theatre — a structure seating over twenty thousand, still standing at Ephesus today. For about two hours the assembly shouted with one voice, "Great is Diana of the Ephesians" (Acts 19:34, Douay-Rheims) (Scripture). Paul wished to address the crowd; the disciples, and certain of the Asiarchs who were his friends, prevented him (Acts 19:30–31) (Scripture). Order was restored not by the church but by the town clerk, who warned the assembly that Rome held cities answerable for unlawful gatherings and that courts and proconsuls existed for lawful complaint (Acts 19:35–40) (Scripture).

The episode is a small masterpiece of civic realism — guilds, theatre assemblies, Asiarchs, proconsular assizes — and historians have long noted how precisely Luke's terminology matches the epigraphic record of first-century Ephesus (Scholarship). The pattern recurs in Acts: when the gospel disrupts profit, from Philippi (Acts 16:19) to Ephesus, riot follows.

Macedonia and the Winter in Corinth (Acts 20:1–3, c. AD 56–57)

After the tumult ceased, Paul took leave of the disciples and departed for Macedonia (Acts 20:1) (Scripture). Luke compresses months of travel into two verses: Paul passed through the Macedonian churches — Philippi, Thessalonica, Berea — exhorting the disciples with many words (Acts 20:2) (Scripture), and came into Greece, "where, when he had spent three months..." (Acts 20:3) (Scripture).

Those three months, on the standard reconstruction, were the winter of c. AD 56–57, spent at Corinth (Scholarship) — sea travel closed for the season, and Corinth was the natural wintering place, the seat of the church Paul had founded on the second journey. It was almost certainly during this Corinthian winter that Paul dictated the Epistle to the Romans (Scholarship): the letter commends Phebe of Cenchrae, Corinth's eastern port (Romans 16:1), and sends greetings from Gaius, "my host," and Erastus, "the treasurer of the city" (Romans 16:23) — an office attested at Corinth by a first-century pavement inscription naming an Erastus (Scholarship). In Romans Paul looks back on a completed arc and forward to Spain by way of Rome, once he has first carried a collection to Jerusalem (Romans 15:24–28) (Scripture).

That collection — money gathered from the Gentile churches of Galatia, Macedonia, and Achaia for the poor of the Jerusalem church (1 Corinthians 16:1–4; Romans 15:26) (Scripture), with the churches of Asia also contributing, to judge from the Asian delegates in the travelling party (Scholarship) — is the quiet engine of the whole return journey. It explains the party of delegates Luke lists in Acts 20:4 — Sopater of Berea; Aristarchus and Secundus of Thessalonica; Gaius of Derbe; Timothy, the Lystran co-worker recruited on the second journey; Tychicus and Trophimus of Asia — representatives of the contributing churches accompanying the gift (Scholarship). A plot against Paul's life, laid as he was about to sail for Syria, forced a change of route: instead of sailing directly, he returned overland through Macedonia (Acts 20:3) (Scripture).

Letters of the Period

The Third Journey frames the central cluster of the Pauline correspondence (Scholarship throughout this section):

• 1 Corinthians — written from Ephesus, c. AD 54–56; Paul himself locates the writing there: "I will tarry at Ephesus until Pentecost" (1 Corinthians 16:8) (Scripture). The letter answers reports and questions from a divided church across the Aegean.
• 2 Corinthians — written from Macedonia, c. AD 55–57, after a painful interim visit and a severe letter, as Paul travelled toward Corinth for the winter; many scholars discern more than one letter combined in its canonical form (Scholarship, disputed).
• Romans — written from Corinth during the three winter months of Acts 20:3, c. AD 56–57; the most systematic exposition of Paul's gospel, preparing his way westward.
• Galatians — placement disputed. On the "South Galatian" early dating it precedes this journey entirely, c. AD 48–49; on the "North Galatian" view it belongs to the Ephesian residency, c. AD 53–55, addressed to churches visited in Acts 18:23 (Scholarship, disputed).

For the manuscript and dating questions behind these judgments, see the library's scholarship and sources pages.

The Return: Troas and the Walk to Assos (Acts 20:6–14)

The returning party divided: the delegates sailed ahead to Troas, while Paul kept the days of Azymes — the feast of Unleavened Bread — at Philippi and sailed afterward, rejoining them at Troas in five days (Acts 20:5–6) (Scripture). Here the narrative shifts back into the first person plural: the "we-passages" resume at Philippi, where they had broken off on the second journey, and most scholars take this as the point where Luke, the traditional author of Acts, rejoined the company in person (Tradition; Scholarship).

At Troas, on "the first day of the week, when we were assembled to break bread" (Acts 20:7, Douay-Rheims) (Scripture) — one of the earliest glimpses of Christian Sunday worship (Scholarship) — Paul, departing on the morrow, prolonged his speech until midnight. A young man named Eutychus, sitting in a third-storey window, sank into sleep and fell, and was taken up dead. Paul went down and embraced him: "Be not troubled, for his soul is in him" (Acts 20:10, Douay-Rheims) (Scripture). The boy was restored alive, and the talking went on until daybreak (Acts 20:11–12) (Scripture).

Then comes one of the most human details in Acts: the company sailed around Cape Lectum to Assos, while Paul, "himself purposing to travel by land" (Acts 20:13, Douay-Rheims) (Scripture), went by the road — a solitary walk of some twenty Roman miles across the neck of the Troad before he boarded at Assos (Acts 20:14) (Scripture). Luke offers no explanation; readers have long seen a man taking a last day alone before a journey he sensed would end in chains (Scholarship, inferential).

Miletus: The Farewell to the Ephesian Elders (Acts 20:15–38)

The coasting voyage southward — Mitylene, opposite Chios, Samos — brought the ship to Miletus, the old Ionian harbour city south of Ephesus in modern Turkey. Paul had "determined to sail by Ephesus, lest he should be stayed any time in Asia. For he hasted, if it were possible for him, to keep the day of Pentecost at Jerusalem" (Acts 20:16, Douay-Rheims) (Scripture). Instead he sent to Ephesus and called the elders of the church to him.

The Miletus discourse (Acts 20:18–35) is unique: the only substantial speech in Acts addressed by Paul to Christians, and the one that reads most like his letters (Scholarship). He reviews his three years of ministry "with all humility, and with tears" (Acts 20:19) (Scripture); declares himself "bound in the spirit" for Jerusalem, knowing only that imprisonment and afflictions await (Acts 20:22–23) (Scripture); charges the elders — called both overseers and shepherds of the flock (Acts 20:28) (Scripture) — to guard the church against wolves that will enter after his departing; and closes with a saying of Jesus preserved nowhere in the Gospels: "It is a more blessed thing to give, rather than to receive" (Acts 20:35, Douay-Rheims) (Scripture).

Then, kneeling down, he prayed with them all; "and there was much weeping among them all; and falling on the neck of Paul, they kissed him, being grieved most of all for the word which he had said, that they should see his face no more" (Acts 20:37–38, Douay-Rheims) (Scripture). They brought him to the ship.

Patara, Tyre, Caesarea: The Road to Jerusalem (Acts 21:1–17)

From Miletus the voyage ran by Cos and Rhodes to Patara on the Lycian coast (Acts 21:1) (Scripture), where the party changed to a merchant vessel crossing open water to Phoenicia. Luke, precise as ever, notes the sea-mark: "when we had discovered Cyprus, leaving it on the left hand, we sailed into Syria" (Acts 21:3, Douay-Rheims) (Scripture) — the island of the first journey passing to port as the ship ran for Tyre, in modern Lebanon.

At Tyre, where the ship unloaded for seven days, the disciples "said to Paul through the Spirit, that he should not go up to Jerusalem" (Acts 21:4) (Scripture) — the first of the escalating warnings that structure this final leg. The farewell on the beach, whole families kneeling in prayer on the shore (Acts 21:5) (Scripture), is among the most tender scenes in Acts. A day at Ptolemais followed, and then Caesarea Maritima, the great harbour city built by Herod on the coast of modern Israel, where the party lodged with Philip the evangelist, one of the seven, whose four daughters prophesied (Acts 21:8–9) (Scripture).

There the warning became theatre. The prophet Agabus came down from Judea, took Paul's girdle, bound his own feet and hands, and declared that the man who owned it would be so bound in Jerusalem (Acts 21:10–11) (Scripture). Companions and local believers alike begged Paul not to go up. His answer closes the journey's spiritual arc: "I am ready not only to be bound, but to die also in Jerusalem, for the name of the Lord Jesus" (Acts 21:13, Douay-Rheims) (Scripture). When he would not be persuaded, they ceased, saying, "The will of the Lord be done" (Acts 21:14) (Scripture).

So the party went up to Jerusalem, where "the brethren received us gladly" (Acts 21:17) (Scripture), likely just before Pentecost, c. AD 57 (Scholarship). Within days Paul would be seized in the temple, rescued by the Roman garrison, and would declare to the crowd, in words that ring through this whole library: "I am a Jew, born at Tarsus in Cilicia" (Acts 22:3, Douay-Rheims) (Scripture). The arrest opens the Caesarean custody and appeal to Caesar that lead into Paul's voyage to Rome.

The Third Journey in the Tarsus Story

Seen from Tarsus, the Third Journey is the moment Paul's world reached its widest span while his roots stayed fixed. It opens on the Cilician road under the Taurus — the landscape of his childhood — and closes with his public self-identification in Jerusalem as a man of Tarsus in Cilicia (Acts 21:39; 22:3) (Scripture). The school-based teaching of the Tyrannus years has often been read against Paul's formation in a city famed for its schools — ancient writers ranked Tarsus with Athens and Alexandria for zeal in learning (Scholarship) — and against his training under Gamaliel in Jerusalem (Acts 22:3) (Scripture). The early travels and the so-called silent years in Tarsus stand behind everything the mature missionary does here.

Those who wish to follow the ground itself — Tarsus, the Cilician plain, and the sites of early Christianity in the region — will find practical orientation in the pilgrimage guide, and open questions gathered on the questions page.
