Featured Teacher: Dr. W. Robert Godfrey

Main Theme & Purpose

This episode concludes a week-long focus on the Middle Ages in church history, spotlighting two key developments: the influence of Pope Gregory the Great and the formative rise and global expansion of Islam. Dr. W. Robert Godfrey explores Gregory's impact on Western Christianity, the birth and spread of Islam, and the religious and cultural dynamics that shaped Europe for centuries. The conversation aims to help listeners understand the historical roots of Christian and Muslim interactions and the enduring significance of these movements.

Key Discussion Points & Insights

1. Pope Gregory the Great: Influence and Legacy

• Role in Shaping the Papacy:
  • Gregory (c. 600 AD) is described as laying the groundwork for an increasingly independent and influential Western papacy, making the church central in Western society.
  • He draws on Augustine's theological roots but diverges significantly in spirit and emphasis.
• Augustinian Influence – With a Twist:
  • Quote from a historian:

    “Almost everything in Gregory has its roots in the teaching of Augustine, and yet scarcely anything is really Augustinian. The fundamental spirit of Augustine has vanished and superstition gains supremacy.” (03:00)

  • Gregory's focus shifts from the internal peace found in God to a fear-driven quest for security via church institutions.
• Doctrine of Repentance and Purgatory:
  • For Gregory, repentance is central; Christians are to be "constantly repenting, constantly recognizing our sinfulness," never fully assured of their standing with God (04:40).
  • He initiates the idea of purgatory—though undeveloped—signifying that sins likely persist beyond this life and need posthumous purification.
• Grace and Merit:
  • Gregory taught,

    "That which is a gift of the omnipotent God becomes our merit." (06:00)

  • God’s grace becomes something measured toward merit, leading to complex interactions between divine gift and human effort.
• Preaching and Pastoral Focus:
  • Despite later Church drift, Gregory emphasized preaching as the primary role of the clergy, a conviction rooted in earlier church figures like John Chrysostom.
  • This preaching focus eroded over time due to declining clerical education in the Middle Ages.

2. Gregory’s Missionary Vision

• Missions to Unreached Areas:
  • Gregory actively promoted conversion efforts, notably to England via Augustine of Kent (not to be confused with Augustine of Hippo), who became Bishop of Canterbury.
  • The conversion of England forms the basis for the longstanding influence of the Archbishop of Canterbury.
• Challenges to the Church:
  • The church faced continual pressures from pagan, heretical (e.g., Arian), and barbarian populations, such as the Magyars.
  • Example: The conversion of King Stephen of Hungary marks a stabilizing milestone.

3. The Rise and Impact of Islam

• Origins and Early Spread:

  • Founded in the 7th century by Muhammad (born c. 570 AD, Mecca), Islam arose in reaction to local paganism, emphasizing uncompromising monotheism:

    "There is no God but God." (13:10)

  • Muhammad’s flight (Hijra) from Mecca to Medina in 622 is a foundational moment; subsequent military and spiritual triumphs established core Islamic teachings and customs.

• Rapid Expansion:

  • Within only a few decades of Muhammad's death (632), Islam conquered vast territories stretching from the Middle East to North Africa and Spain.
  • Notable milestones:
    • Jerusalem captured shortly after Muhammad’s death.
    • By 707: North Africa under Islamic rule.
    • 711: Entry into Spain.
    • 732: Advance halted at Tours, France.
    • Islam remained in Spain until 1492.
  • Further expansion east into Persia, Afghanistan, India; major moments like the capture of Constantinople in 1453 and threat to Vienna until 1683.

• Medieval Christian Perception of Islam:

  • Islam posed a significant and enduring challenge to Christian Europe.
  • In the Reformation era:

    "It was often difficult to be sure who the Antichrist really was. Was it the Pope or was it Mohammed? It was a close call for a number of the reformers." (19:10)

    • Reformers sometimes symbolized the Pope and Muhammad as apocalyptic beasts.

• Doctrinal Contrasts:

  • Islam claims continuity and supersession with Judeo-Christian traditions—recognizing Jesus as a prophet, but denying the incarnation, crucifixion, and resurrection.

    "From a Muslim point of view, the claim that Jesus is divine is polytheistic... their doctrine of the Trinity is inherently tinged with polytheism." (20:45)

  • The Qur’an is seen as direct divine revelation—"not a book of history" but "directions," often without logical sequence (21:20).

• God’s Character in Islam vs. Christianity:

  • Allah is defined by transcendence and power, less by love;

    "There seems to be little love in the conception of Allah. He is the great one, the majestic One, who must be obeyed and submitted to." (22:00)

    • Key phrase: "God is great" vs. the biblical emphasis, "God is good."
  • Islam stresses submission (the literal meaning of "Islam"), determinism, and lack of assurance in salvation.

• Cultural and Legal Aspects:

  • Religion and culture in Islam are one:

    "Wherever it spreads, it must take not only its religion but its whole set of cultural values and laws. They are indivisible." (24:14)

  • The Five Pillars of Islam:
    1. Confession ("There is no God but Allah, and Muhammad is his prophet")
    2. Prayer (five times daily facing Mecca)
    3. Almsgiving
    4. Fasting (Ramadan)
    5. Pilgrimage to Mecca

• Societal Observations and Gender Roles:

  • Islam is described as "hard on women" with divorce, polygamy, and social restrictions favoring men.
  • Yet, Dr. Godfrey relays a Muslim professor’s insight: Islam "survives and flourishes because the women support it so passionately" (24:50).
  • Only Arabic Quran is authoritative—translational limitations maintain the cultural unity.

• Enduring Tension and Eschatology:

  • Islam’s expansionist drive seen as religious and cultural, marked by a sense of irreversibility—lands won to Islam are never to be lost.

    "It is a religion that is also a culture. The two are indistinguishable... and they have a strong eschatology that where Islam spreads, it will never retreat." (25:04)

  • This contributed to the persistent clash with Christian Europe throughout the Middle Ages.

Memorable Quotes & Moments

• On Gregory’s Spiritual Climate:

  "The great center of Christianity for Gregory was repentance... constantly seeking grace and never quite sure where we stood with God." (04:40)

• On Islam’s Foundational Belief:

  "There is but one God and Muhammad is his prophet." (14:35)

• Christian Perception During the Reformation:

  "It was a close call for a number of the reformers… the Pope or Mohammed?" (19:10)

• On Contrasting Divine Attributes:

  "God is great. It's interesting when you look at the Old Testament... the dominant statement would be, God is good." (22:50)

• On the inseparability of Religion and Culture in Islam:

  "It is a religion that is also a culture. The two are indistinguishable." (24:14)

Summary Takeaways

• The rise of Islam was both rapid and far-reaching, redefining religious and cultural boundaries that would challenge Christian Europe for centuries.
• Fundamental differences in theology (monotheism, Christology), culture, and views on church and state have distinguished Christianity and Islam since their beginnings.
• Understanding this history equips modern Christians with perspective on present-day religious interactions and tensions.
