TURNING POINTS Decisive Moments in the History of Christianity THIRD EDITION Mark A. Noll, Turning Points: Decisive Moments in the History of Christianity, Third Edition (Grand Rapids, MI: Baker Academic, 2012), iii.

Introduction: The Idea of Turning Points

Noll introduces his methodology for understanding Christian history through twelve pivotal moments. He argues that these "turning points" are not merely significant events but moments that fundamentally reoriented the trajectory of Christian belief, practice, and institutional life. He emphasizes that these moments often had long-lasting, unforeseen consequences, shaping subsequent centuries. Noll also discusses the challenges of historical interpretation, the role of divine providence, and the importance of recognizing both continuity and change in the Christian tradition. He sets the stage for examining how specific decisions, theological developments, or political shifts at these junctures created new paths for Christianity globally.

Turning Point 1: The Fall of Jerusalem (AD 70)

This chapter examines the destruction of Jerusalem by the Romans in AD 70 as a crucial moment for early Christianity. Noll argues that this event forced Christianity to decisively separate from its Jewish roots, shifting its geographical and cultural center from Jerusalem to the broader Greco-Roman world. The loss of the temple and the Jewish state meant that Christianity could no longer be seen as merely a sect within Judaism. This turning point facilitated the Gentile mission, leading to a more universal and less ethnically defined faith. It also spurred the development of Christian self-identity, its own scriptures, and its distinct institutional structures, laying the groundwork for its expansion across the Roman Empire.

Turning Point 2: The Council of Nicaea (AD 325)

Noll highlights the Council of Nicaea as the first ecumenical council, convened by Emperor Constantine, which addressed the Arian controversy concerning the nature of Christ. The council's affirmation of Christ's full divinity, expressed in the Nicene Creed with the term homoousios (of the same substance as the Father), was a foundational theological declaration. This turning point established a precedent for imperial involvement in church affairs and the use of councils to define orthodox doctrine. It marked a significant step in the institutionalization of Christianity within the Roman Empire, shaping the future development of Trinitarian theology and the relationship between church and state for centuries.

Turning Point 3: The Council of Chalcedon (AD 451)

This chapter focuses on the Council of Chalcedon, which definitively articulated the doctrine of Christ's two natures—fully divine and fully human—united in one person without confusion, change, division, or separation. Noll explains that this council resolved the Christological controversies that followed Nicaea, particularly against Monophysitism. While establishing a theological consensus for the majority of the church, it also led to significant schisms, particularly with the Coptic, Syrian, and Armenian Orthodox churches, which rejected its formulations. Chalcedon solidified the theological framework for understanding the incarnation, profoundly influencing Western and Eastern Orthodox Christianity, and demonstrating the ongoing struggle to define core Christian beliefs.

Turning Point 4: The Benedictine Rule (AD 530)

Noll identifies the development of the Benedictine Rule by Benedict of Nursia around AD 530 as a pivotal moment for Western Christianity. This rule provided a structured, moderate, and enduring framework for monastic life, emphasizing prayer, work (ora et labora), and communal living under an abbot. The Benedictine monasteries became centers of learning, agricultural innovation, and spiritual discipline during the early Middle Ages, preserving classical knowledge and Christian culture amidst the collapse of the Roman Empire. This turning point fundamentally shaped the spiritual landscape of Europe, influencing liturgy, education, and the very concept of Christian discipleship, and serving as a model for subsequent monastic orders.

Turning Point 5: The Coronation of Charlemagne (AD 800)

The coronation of Charlemagne as Holy Roman Emperor by Pope Leo III on Christmas Day, AD 800, is presented by Noll as a defining moment for the relationship between church and state in the West. This event symbolized the fusion of Germanic, Roman, and Christian elements, establishing the concept of a "Holy Roman Empire" and solidifying the pope's role as a kingmaker. It marked a new era of political and religious alliance, where the church provided legitimacy to rulers, and rulers protected and promoted the church. This turning point profoundly influenced the development of Western political thought, the papacy's temporal power, and the cultural identity of medieval Europe, setting the stage for future conflicts and collaborations between secular and ecclesiastical authorities.

Turning Point 6: The Great Schism (AD 1054)

Noll examines the Great Schism of 1054 as the formal separation between the Eastern Orthodox and Western Roman Catholic churches. While the schism had deep roots in theological differences (e.g., the filioque clause, papal supremacy), cultural divergences (Greek vs. Latin), and political rivalries (Constantinople vs. Rome), the mutual excommunications in 1054 are seen as the definitive break. This turning point created two distinct branches of Christianity, each developing its own unique traditions, liturgies, and theological emphases. It profoundly impacted the geopolitical landscape of Europe and the Middle East, leading to centuries of separate development and mutual misunderstanding, and shaping the identities of millions of Christians to this day.

Turning Point 7: The Diet of Worms (AD 1521)

The Diet of Worms in 1521, where Martin Luther famously refused to recant his writings unless convinced by Scripture or plain reason, is presented as the decisive moment for the Protestant Reformation. Noll argues that Luther's stand before Emperor Charles V and the imperial diet crystallized the challenge to papal authority and traditional church doctrine. This event marked the irreversible break with Rome for many in Northern Europe, unleashing a torrent of theological, social, and political changes. It underscored the principle of sola Scriptura and the individual conscience, leading to the formation of new Protestant denominations and fundamentally reshaping the religious map of Europe and, subsequently, the world.

Turning Point 8: The English Act of Supremacy (AD 1534)

Noll identifies the English Act of Supremacy in 1534, which declared King Henry VIII the "Supreme Head of the Church of England," as the pivotal moment for the English Reformation. Unlike the continental Reformation, which began primarily with theological disputes, the English break with Rome was initially driven by political and dynastic concerns, specifically Henry's desire for an annulment. This act established the unique Erastian character of the Church of England, where the monarch holds ultimate authority over the church. It led to a distinct trajectory for Anglicanism, blending Catholic tradition with Protestant theology, and profoundly influenced the religious and political history of Britain and its global empire.

Turning Point 9: The Founding of the Jesuits (AD 1540)

The founding of the Society of Jesus (Jesuits) by Ignatius of Loyola in 1540 is presented as a crucial turning point for the Catholic Reformation (or Counter-Reformation). Noll emphasizes the Jesuits' commitment to education, missionary work, and absolute obedience to the Pope. Their rigorous spiritual discipline, intellectual prowess, and global reach made them the spearhead of Catholic renewal and expansion. They played a vital role in stemming the tide of Protestantism in Europe and spreading Catholicism to new continents, including the Americas and Asia. This turning point revitalized the Catholic Church, demonstrating its capacity for internal reform and global engagement in response to the challenges of the Protestant Reformation.

Turning Point 10: The Conversion of the Wesleys (AD 1738)

Noll highlights the Aldersgate experience of John Wesley in 1738, where he felt his "heart strangely warmed," as the catalyst for the Evangelical Revival and the rise of Methodism. This personal conversion experience, shared by his brother Charles and others, led to a powerful movement emphasizing personal piety, evangelism, social concern, and lay participation. The Wesleys' itinerant preaching, hymn writing, and organizational genius transformed the religious landscape of Britain and America. This turning point revitalized Protestantism, gave birth to new denominations, and profoundly influenced subsequent missionary movements and social reform efforts, shaping modern evangelical Christianity worldwide.

Turning Point 11: The Edinburgh Missionary Conference (AD 1910)

The Edinburgh Missionary Conference of 1910 is presented by Noll as a watershed moment for the global expansion of Christianity and the nascent ecumenical movement. This conference brought together Protestant missionary leaders from around the world to strategize for "the evangelization of the world in this generation." It symbolized the peak of Western missionary enterprise and marked a shift towards greater cooperation among denominations. More importantly, it laid the groundwork for the modern ecumenical movement, fostering a sense of shared purpose among diverse Christians. This turning point underscored Christianity's increasing global reach and its potential for unity amidst denominational and cultural differences, anticipating the shift of Christianity's center of gravity to the Global South.

Turning Point 12: The Second Vatican Council (AD 1962-65)

Noll identifies the Second Vatican Council (Vatican II) as a monumental turning point for the Roman Catholic Church in the modern era. Convened by Pope John XXIII, the council aimed at aggiornamento (renewal and updating) and resourcement (return to sources). It led to significant reforms, including liturgical changes (Mass in vernacular), a renewed emphasis on the laity, a more open stance towards other Christian traditions (ecumenism), and engagement with the modern world. This turning point profoundly reshaped Catholic identity, worship, and its relationship with other faiths and secular society, influencing millions globally and demonstrating the church's capacity for self-reflection and adaptation in a rapidly changing world.

Conclusion: The Future of Turning Points

In the conclusion, Noll reflects on the ongoing nature of Christian history and the potential for future turning points. He reiterates the importance of understanding the past to navigate the present and future challenges facing Christianity. He discusses the shifting demographics of global Christianity, particularly the growth in the Global South, and speculates on how this might lead to new decisive moments. Noll encourages readers to remain attentive to how God continues to work through human events, shaping the church's trajectory, and to consider what future events might be recognized as "turning points" by historians centuries from now, emphasizing the dynamic and unfolding nature of Christian history.
