Q. What were the core beliefs of Christian doctrine by the time of the council of Nicea and how were the core beliefs about Christian doctrine different when Martin Luther nailed his 95 theses to the door of the church at Wittenberg? Or were core doctrines largely the same?

The core beliefs of Christian doctrine remained largely consistent in many respects between the Council of Nicaea (325 AD) and the time of Martin Luther (1517 AD). However, there were notable differences in emphasis, interpretation, and practice due to developments within the church over those centuries. Here’s a comparison:

Core Beliefs of Christian Doctrine at Nicaea (325 AD)

The Council of Nicaea formalized key aspects of Christian orthodoxy in response to theological controversies like Arianism. By this time, the following were widely accepted as core Christian doctrines:

  1. The Trinity:
    • The Father, Son, and Holy Spirit are co-equal, co-eternal, and of the same divine substance (homoousios).
    • The Nicene Creed affirmed the full divinity of Jesus Christ.
  2. Christology:
    • Jesus is both fully God and fully human.
    • The Son is “begotten, not made,” emphasizing His eternal relationship with the Father.
  3. Salvation:
    • Salvation comes through Jesus Christ’s incarnation, death, and resurrection, reconciling humanity to God.
    • Faith in Christ and baptism were seen as central to salvation.
  4. Authority of Scripture and Apostolic Tradition:
    • The Scriptures (Old Testament and emerging New Testament canon) were authoritative.
    • Apostolic teaching, as handed down through bishops, was the foundation of church doctrine.
  5. The Church:
    • The church was understood as the visible, unified body of Christ, governed by bishops in apostolic succession.
    • The sacraments (e.g., baptism and the Eucharist) were central to Christian life.

Core Beliefs of Christian Doctrine at the Time of Luther (1517 AD)

By the time of Luther, the church had undergone significant theological and institutional developments, many of which Luther would challenge. Core Christian doctrines still included the Trinity, the nature of Christ, and salvation through Christ, but several differences in emphasis and additional doctrines had emerged:

  1. The Trinity and Christology:
    • The doctrines established at Nicaea and later councils (e.g., Chalcedon, 451 AD) were still foundational and largely undisputed.
  2. Salvation:
    • The medieval Catholic Church emphasized a synergistic view of salvation: faith and good works, aided by grace, were necessary.
    • The church also taught the necessity of the sacraments (seven by this time, including baptism, Eucharist, confession, and penance) as channels of grace.
  3. Purgatory and Indulgences:
    • The doctrine of purgatory, absent at Nicaea, had developed by the medieval period.
    • Indulgences (remissions of temporal punishment for sin) were tied to the belief in purgatory and became a significant issue for Luther.
  4. The Church and Papal Authority:
    • The pope was regarded as the supreme authority in the church, and apostolic succession was essential for legitimate teaching and sacraments.
    • Church councils, canon law, and papal decrees supplemented Scripture as sources of authority.
  5. Scripture and Tradition:
    • The medieval church upheld both Scripture and unwritten tradition as equally authoritative.
    • The Bible was largely inaccessible to laypeople, as it was predominantly in Latin (the Vulgate).

Key Differences Between Nicaea (325) and Luther’s Time (1517)

While many foundational beliefs (e.g., the Trinity, Christology, and the centrality of Christ for salvation) were unchanged, significant differences emerged in practice and interpretation:

  1. Scriptural Accessibility:
    • At Nicaea, the focus was on defining orthodoxy through Scripture and apostolic teaching. By Luther’s time, access to Scripture had been limited by its use in Latin and the church’s control over its interpretation.
    • Luther emphasized sola scriptura (Scripture alone) as the ultimate authority, challenging the Catholic view that tradition held equal weight.
  2. Salvation:
    • Nicaea’s focus was on Christ’s work as the basis for salvation. By Luther’s time, salvation had become tied to church-administered sacraments and works, which Luther criticized as contrary to the biblical message of justification by faith alone (sola fide).
  3. Church Authority:
    • The Nicene church was unified under the leadership of bishops. By Luther’s time, the papacy had grown into a powerful institution, with extensive political influence and financial corruption.
    • Luther rejected papal authority, arguing for the priesthood of all believers.
  4. Purgatory and Indulgences:
    • These doctrines and practices did not exist at Nicaea but were central to the medieval church. Luther’s 95 Theses directly opposed indulgences and questioned the church’s teachings on purgatory.

What Remained Largely the Same

  • The core doctrines of the Trinity, Christology, and the redemptive work of Christ remained unchanged.
  • Baptism and the Lord’s Supper (Eucharist) were still central sacraments, though their interpretation and administration differed.

Conclusion

The core doctrines of Christianity established at Nicaea largely endured through the centuries, but by Luther’s time, significant theological and institutional developments had layered over them. Luther’s Reformation was not a rejection of Nicene orthodoxy but a call to reform the church’s practices and return to a purer understanding of Scripture and salvation.
