The intersection of archaeology and missiology offers a rich field for exploring how early Christians navigated complex sociocultural terrains in Asia Minor. In the forthcoming Gods, Emperors, Philosophers, and a New Movement, I argue that the material culture of the first three centuries presents more than historical data—it offers theological and missiological implications for practical lessons about church planting movements today. In this blog, I propose seven principles drawn from archaeological discoveries across the cities of Revelation that illuminate patterns of early Christian practice and ecclesial formation. These are not merely historical insights; they are missiological trajectories rooted in real places, among real people, engaging real powers.
Ephesos: Theophilos, Tyrannos, and Trophimus—The Early Church Was Not Hidden
Ephesos, arguably the most prominent of the seven churches, provides a compelling case for the public nature of early Christianity. Inscriptions found in the prytaneion include names such as Theophilos, a civic leader whose affiliation with the Kouretes and role in annual processions to Artemis’ birthplace, suggest a position of cultural prominence. If this Theophilos is Luke’s patron, as numismatic and epigraphic data suggest, then the Gospel and Acts were not directed at outsiders but insiders—people of influence within society’s elite structures.
Likewise, the inscriptional evidence for Tyrannos—another Kouretes—points to Paul’s deliberate choice of public teaching space (Acts 19:9–10). And Trophimus, a priest whose name appears on the same inscription with Theophilos and Tyrannos, becomes a Christian and travels on mission with Paul (Acts 20:4, 21:29; 1 Tim 4:10). He reflects the mobility and passion of the Ephesian believers. These figures were not obscure. The ekklēsia in Ephesos was visibly embedded within the civic framework.
Missiological Application: Church planting movements should not aim to remain under the radar. Visibility within the public, social, and cultural life of a community is not optional—it is inherent to the nature of the gospel’s proclamation and the formation of ekklēsia.
Smyrna: The Word Square in the Marketplace—Creative Gospel Witness in the Public Sphere
Perhaps one of the most intriguing archaeological finds is the Logos word square discovered in the Smyrna agora. This square, etched into the plaster walls of the cryptoporticus, consists of five Greek words arranged in a five-by-five cross, with λόγος (Word) at the center. While not palindromic like the better-known Sator Square, it carries Christological and possibly Trinitarian meaning: μήλον (apple or fruit), ἡδονή (delight), λόγος (Word), ὄνομα (name), and νήσας (to float or spin).
The centrality of λόγος evokes John 1:1 and signals the identity of Jesus as the eternal Word. Whether understood as theological graffiti, catechetical tool, or coded evangelistic message, it demonstrates how early believers used creative, context-sensitive forms to declare their faith.
Missiological Application: Movements today must embrace contextually creative expressions of the gospel. The public square—whether digital or physical—is not neutral. It must be engaged with imagination and clarity grounded in Christ.
Pergamon: The Pressure to Conform—Cultural Accommodation as a Constant Threat
Pergamon, home to one of the great libraries of antiquity and steeped in emperor worship, presents a sobering lesson. Archaeology reveals strong allegiance to Greco-Roman religion and intellectualism, but almost no trace of an enduring Christian witness. Revelation 2:14-15 condemns the community’s assimilation into idolatrous practices and cultural accommodation.
The lesson from Pergamon is twofold: Without deep discipleship and theological formation, the church will drift into syncretism. And without public intellectual engagement, it risks irrelevance.
Missiological Application: Movements must form resilient disciples who can discern and resist cultural pressures while engaging public thought with theological clarity. Faithfulness, not mere relevance, must define our ecclesial posture.
Thyatira: Vocational Identity and the Foundations of the Ekklēsia
Archaeological data from Thyatira indicate a strong presence of trade guilds. In Revelation, the critique is focused on the infiltration of Jezebel’s teaching, likely associated with economic participation in guild feasts involving idolatry. Yet these guilds also served as the primary social and vocational networks through which the gospel spread. Places of peace, if you will.
Christianity did not emerge in a vacuum but leveraged existing social structures. These vocational associations became seedbeds for the formation of ekklēsia—not by abandoning their trades, but by reorienting their purpose toward Christ.
Missiological Application: Contemporary movements must not extract believers from their cultural vocations but equip them to reframe their labor as worship and witness. Marketplace engagement is foundational to ecclesial expression.
Sardis: Religious Space and the Danger of Syncretistic Layers
At Sardis, archaeology reveals how religious space evolved. The juxtaposition of synagogue and possible Christian shops raises critical questions about shared spaces and syncretism. While adaptation of space for Christian use seems practical, it also introduces risk: layering the ekklēsia with cultural or religious forms that dilute its identity.
The early church’s use of public space was strategic but not indiscriminate. Jesus’ words to Sardis—“you have the reputation of being alive, but you are dead” (Rev 3:1)—are a chilling indictment of outward religiosity without spiritual vitality.
Missiological Application: Movements must assess their use of space. Adaptive reuse of existing structures can be fruitful but must avoid entanglements that compromise gospel integrity or confuse ecclesial identity.
Philadelphia: Montanus and the New Prophecy—The Caution of Early Enthusiasm
The archaeological and literary record from Philadelphia intersects with the Montanist movement—a prophetic renewal that emerged in the late second century. While it reflected zeal for purity and eschatological urgency, it also demonstrates the danger of premature elevation of untested leaders.
The early church wrestled with discernment. Jesus’ commendation of Philadelphia in Revelation 3:7-13 highlights their faithfulness, but history reminds us of the need for maturity in leadership selection.
Missiological Application: Movements must not be hasty in appointing leaders. Enthusiasm must be matched by tested character and doctrinal soundness. Leadership development is as important as leadership deployment.
Laodicea: Jesus at the Door—The Call to Take Christ Seriously
In Laodicea, Jesus’ rebuke is sharp: “You are neither cold nor hot” (Rev 3:15). The archaeological record complements this critique with evidence of wealth, comfort, and self-sufficiency. Christianity here had become complacent. Yet Jesus stands at the door and knocks (Rev 3:20), not to an individual, but to a church.
Missiologically, this image is both invitation and indictment. Jesus is near—but outside.
Missiological Application: Movements must prioritize intimacy with Christ over performance metrics. Success is not in numbers but in fidelity. Jesus must be central—not merely doctrinally, but relationally and practically.
Implications for Moving Forward: Adaptive Missiology & Ecclesiology
Drawing on the archaeological record, these seven principles converge in a call for adaptive missiology. Adaptive does not mean syncretistic; it means responsive, thoughtful, and contextually grounded.
Adaptive Missiology Asks:
- What has God done in the history of your place and what is He doing now?
- How will you connect with your history? And how do you see your story intersecting with Jesus’?
- How will you use what you learn about your past to connect with your present?
- How will you tell your story in a way that intersects with others?
- Just as Jesus’ story intersects with yours, how does His story intersect with those you engage?
Adaptive Ecclesiology Responds:
- What historical models demonstrate adaptive ecclesiology?
- How do they inform our adaptation today?
- Where are the places of peace in your community?
- What would ekklēsia look like there?
These are not rhetorical questions. They are the beginning of a journey into a theological and missiological reflection that must remain grounded in both the biblical text and the material evidence that continues to emerge from the soil of ancient cities.
Conclusion
Archaeology does not merely confirm the biblical narrative—it expands our understanding of it. The record from Asia Minor affirms that early Christianity was public, creative, vocational, resilient, discerning, and Christ-centered. These are not just ancient traits; they are blueprints for contemporary church planting movements.
The church must engage civic leaders and remain visible in the agora. It must be discerning unlike Pergamon, engaging in places of peace as in Thyatira, wise about leadership as in Philadelphia, faithful like Sardis, and ever listening for the knock like Laodicea. This is adaptive missiology. This is adaptive ecclesiology.

Archaeology and Early Christian Missiology
Unearthing the Past, Illuminating the Mission
Join Dr. Cooper on an exploration of the dynamic intersection of archaeology and missiology in the study of early Christian movements with a focus on Asia Minor. Drawing on the material culture and historical records of the Seven Churches of Revelation, the emersive learning experience delves into how archaeology informs both ancient and modern mission practices. The course will also discuss how early Christian communities adapted to cultural, political, and economic pressures while remaining faithful to the gospel.
Pick up Dr. Cooper’s latest book
Religions, politics, and education shaped the cultural world of Asia Minor where a new faith emerged that would change history. Gods, Emperors, Philosophers, and a New Movement uncovers how the earliest Christians navigated—and often disrupted and adapted—the dominant forces of their age. Drawing on decades of research, fieldwork, and teaching, Michael T. Cooper takes readers beneath the surface of Ephesos, Smyrna, Pergamon, and other cities to reveal how temples, inscriptions, and civic spaces illuminate the missionary impulse of the first Christians. Far from being silent, the archaeological record testifies to their resilience, creativity, and bold proclamation of the gospel in a world saturated with competing loyalties.
This is more than history. By examining how the early church encountered powerful religious traditions, political ideologies, and systems of education, today’s missionaries and church leaders gain fresh vision for gospel engagement in their own pluralistic and contested contexts. The dynamics that shaped mission in the first centuries—identity, power, worldview, and cultural disruption—remain central to how the good news advances today. This book is an invitation to rediscover the mission of God in the archaeological record and to discern its enduring relevance for faithful witness in the twenty-first century.
