How Did Early Christianity Become What It Is Today?

Jesus proclaimed that God was about to redeem the world.
Paul believed that all Israel would be saved.
Christianity emerged in a world full of gods.

By the fifth century, Christianity taught that most of humanity was condemned, the Jews were damned, and only one God was allowed.

The first followers of Jesus did not share a single set of beliefs, practices, or scriptures.  It is a tangled web of diverse beliefs, competing communities, and evolving traditions.  Over the course of five centuries, Christianity changed as it moved from Jewish communities in Judea through the Roman Empire.  

In this course, you’ll explore how those changes happened, why so many early Christian groups disagreed with one another, and how one version of Christianity eventually came to dominate the rest.

course syllabus

semester length: 20 Lectures - starts Jan 27th


Jan 27 | Lesson 1: Mediterranean Culture: Gods and Greeks

Rome inherited a world shaped by Alexander the Great (d. 323 BCE). It was a world full of various ethnic groups, thus, a world full of gods. These two introductory lectures will establish the historical and cultural context for our topic, tracing the ways that pagans and Jews interacted especially within the Empire’s fundamental religious institution, the ancient city.

Jan 29 | Lesson 2: Mediterranean Culture: Hellenistic Judaism

Rome inherited a world shaped by Alexander the Great (d. 323 BCE). It was a world full of various ethnic groups, thus, a world full of gods. These two introductory lectures will establish the historical and cultural context for our topic, tracing the ways that pagans and Jews interacted especially within the Empire’s fundamental religious institution, the ancient city.

Feb 3 | Lesson 3: Beginnings: From Jesus to Christ

We begin our historical journey with the figure of Jesus of Nazareth and the movement that formed around him. We will explore the transition from the historical Jesus to the Christ of faith, examining the earliest Gospel accounts. Then, we turn to Paul, the "Pagans' Apostle," to understand his pivotal role in spreading this Jewish message to the Gentile world and the theological foundations he laid for the nascent church.

Feb 5 | Lesson 4: Beginnings: Paul, the Pagans’ Apostle

We begin our historical journey with the figure of Jesus of Nazareth and the movement that formed around him. We will explore the transition from the historical Jesus to the Christ of faith, examining the earliest Gospel accounts. Then, we turn to Paul, the "Pagans' Apostle," to understand his pivotal role in spreading this Jewish message to the Gentile world and the theological foundations he laid for the nascent church.

Feb 10 | Lesson 5: Christians, the High God, and the Jews: Marcion and the Invention of the New Testament

As the movement grew, early Christians grappled with their relationship to the Jewish scriptures and the nature of God. We will examine the radical ideas of Marcion, who proposed a complete break from the "Old Testament" God, and the Gnostic teachers like Valentinus and Ptolemy, who envisioned a higher, spiritual reality beyond the creator of this world. These controversies were crucial in spurring the formation of the New Testament canon and orthodox theology.

Feb 12 | Lesson 6: Christians, the High God, and the Jews: Valentinus, Ptolemy, and the God of this Age

As the movement grew, early Christians grappled with their relationship to the Jewish scriptures and the nature of God. We will examine the radical ideas of Marcion, who proposed a complete break from the "Old Testament" God, and the Gnostic teachers like Valentinus and Ptolemy, who envisioned a higher, spiritual reality beyond the creator of this world. These controversies were crucial in spurring the formation of the New Testament canon and orthodox theology.

Feb 17 | Lesson 7: Jews and Heretics: Justin Martyr and Israel

Defining "orthodoxy" often meant defining what it was not. We will study Justin Martyr's Dialogue with Trypho to see how early Christians constructed their identity in opposition to Judaism, claiming the title of the "True Israel." We will also look at Irenaeus of Lyons, who cataloged and refuted various "heresies," establishing the concepts of apostolic succession and the rule of faith as safeguards for the emerging catholic tradition.

Feb 19 | Lesson 8: Jews and Heretics: Irenaeus and Heresy

Defining "orthodoxy" often meant defining what it was not. We will study Justin Martyr's Dialogue with Trypho to see how early Christians constructed their identity in opposition to Judaism, claiming the title of the "True Israel." We will also look at Irenaeus of Lyons, who cataloged and refuted various "heresies," establishing the concepts of apostolic succession and the rule of faith as safeguards for the emerging catholic tradition.

Feb 24 | Lesson 9: Charisma and Christianity: Prophecy

The early church was a community fueled by charismatic power and the expectation of the end times. We will explore the role of prophecy and the apocalyptic worldview that permeated early Christian thought. Furthermore, we will examine the phenomenon of martyrdom, reading the moving accounts of Perpetua and Felicitas, to understand how the willingness to die for the faith became a powerful tool for identity formation and resistance against the Roman state.

Feb 26 | Lesson 10: Charisma and Christianity: Martyrdom

The early church was a community fueled by charismatic power and the expectation of the end times. We will explore the role of prophecy and the apocalyptic worldview that permeated early Christian thought.

Mar 3 | Lesson 11: The Christian Body: Ascetic Enthusiasms

How did early Christians view the physical body? We will investigate the rise of asceticism, from Paul's teachings on celibacy to the radical renunciation of family and society found in the Acts of Paul and Thecla and the early monastic movement. We will discuss how the discipline of the body became a path to spiritual perfection and how these practices offered new roles and agencies, particularly for women, within the church.

Mar 5 | Lesson 12: The Christian Body: Christ’s Bride and Body

How did early Christians view the physical body? We will investigate the rise of asceticism, from Paul's teachings on celibacy to the radical renunciation of family and society found in the Acts of Paul and Thecla and the early monastic movement.

Mar 17 | Lesson 13: Christ and Empire: Constantine

The conversion of the Emperor Constantine marked a seismic shift in the history of Christianity. We will trace the transformation of a persecuted sect into an imperial religion, examining the political and theological consequences of this alliance. We will also discuss the "Arian" controversy, the Council of Nicaea, and the brief pagan revival under Julian the Apostate, analyzing how the church adapted to its new status as a pillar of Roman power.

Mar 19 | Lesson 14: Christ and Empire: Imperial Christianity

The conversion of the Emperor Constantine marked a seismic shift in the history of Christianity. We will trace the transformation of a persecuted sect into an imperial religion, examining the political and theological consequences of this alliance.

Mar 24 | Lesson 15: Christian Paideia: Origen - God and the Universe

Origen of Alexandria stands as the intellectual giant of the pre-Nicene church. We will delve into his masterwork, On First Principles, to understand his grand synthesis of Christian scripture and Greek philosophy. We will explore his daring speculations on the pre-existence of souls, the nature of the Godhead, and the ultimate restoration of all things, seeing how he established the framework for future theological debate.

Mar 26 | Lesson 16: Christian Paideia: Origen - Free Will and Revelation

Apr 7 | Lesson 17: Augustine, The City of God: Divine Justice and Human Freedom

Augustine of Hippo's City of God is a monumental response to the crisis of the Roman Empire's collapse. We will read key sections of this masterpiece to understand Augustine's theology of history, his doctrine of original sin, and his distinction between the City of God and the City of Man. We will also examine his complex views on the Jewish people and the role of the church in a fallen world.

Apr 9 | Lesson 18: Augustine, The City of God: Israel and Empire

Apr 21 | Lesson 19: Endings: Augustine - Flesh, History, and Redemption

In our final sessions, we conclude our study of Augustine with his vision of the end times, the resurrection of the body, and the eternal blessedness of the saints. We will then look at the "end" of ancient Christianity as the Western Empire disintegrated, discussing how the church, through its bishops and the cult of the saints, survived the political collapse to become the foundation of medieval Christendom.

Apr 23 | Lesson 20: The End of Ancient Christianity

In our final sessions, we conclude our study of Augustine with his vision of the end times, the resurrection of the body, and the eternal blessedness of the saints.
