Why This Matters

Understanding Christian denominations isn't about memorizing a list of church names—it's about grasping the theological fault lines that have shaped Western civilization for two millennia. You're being tested on how different Christian communities answer fundamental questions: Where does religious authority come from? How does salvation work? What role do rituals play in connecting humans to the divine? These questions drove the Great Schism of 1054, fueled the Protestant Reformation, and continue to influence everything from politics to art to social movements today.

Each denomination represents a distinct answer to these core questions, and exam questions will ask you to compare and contrast these responses. Don't just memorize that Baptists practice immersion baptism—understand why they reject infant baptism (believer's choice) and how that connects to their emphasis on individual faith and congregational autonomy. When you can trace a denomination's practices back to its theological principles, you're thinking like a scholar of religion.


Apostolic Traditions: Authority Through Historical Continuity

These denominations trace their authority directly to the apostles and emphasize unbroken tradition as a source of religious truth alongside scripture. They share a sacramental worldview where rituals are genuine channels of divine grace, not merely symbolic acts.

Roman Catholicism

  • Papal authority—the Pope serves as the supreme spiritual leader and final arbiter of doctrine, a role Catholics trace to Peter as the first bishop of Rome
  • Seven sacraments structure the spiritual life, with the Eucharist understood as the literal body and blood of Christ (transubstantiation)
  • Scripture and Tradition together form the basis of teaching, with the Magisterium (teaching authority) interpreting both for the faithful

Eastern Orthodoxy

  • Autocephalous structure—independent national churches (Greek, Russian, Serbian) each led by bishops, with no single supreme leader like the Pope
  • Divine Liturgy serves as the central act of worship, emphasizing mystical participation in Christ's sacrifice rather than juridical categories of salvation
  • Icons as theology—sacred images function as "windows to the divine," not mere decoration, reflecting the Orthodox emphasis on the incarnation sanctifying matter

Anglicanism

  • Via media ("middle way")—deliberately positions itself between Catholic sacramentalism and Protestant emphasis on scripture alone
  • Three-legged stool of authority: scripture, tradition, and reason work together in theological reflection
  • Archbishop of Canterbury provides spiritual leadership, but governance remains decentralized through national provinces and synods

Compare: Roman Catholicism vs. Eastern Orthodoxy—both claim apostolic succession and emphasize sacraments, but they differ on papal authority (centralized vs. conciliar) and the filioque clause regarding the Holy Spirit. If asked about the Great Schism of 1054, these theological differences are your starting point.


Reformation Traditions: Scripture as Supreme Authority

The Protestant Reformation of the 16th century produced denominations united by sola scriptura (scripture alone) and sola fide (faith alone) but divided on questions of church governance, sacraments, and predestination.

Lutheranism

  • Justification by faith—Martin Luther's central insight that salvation comes through grace received by faith, not earned through works
  • Two sacraments retained: baptism and Eucharist, with Luther teaching the real presence of Christ "in, with, and under" the bread and wine
  • Augsburg Confession (1530) codifies Lutheran beliefs and remains the foundational doctrinal statement for Lutheran churches worldwide

Calvinism (Reformed Tradition)

  • Sovereignty of God stands as the organizing principle—God's will is supreme in all things, including salvation
  • TULIP summarizes the Five Points: Total depravity, Unconditional election, Limited atonement, Irresistible grace, Perseverance of the saints
  • Predestination teaches that God has already chosen who will be saved, emphasizing human inability to earn or choose salvation

Compare: Lutheranism vs. Calvinism—both emerged from the Reformation and affirm sola scriptura, but they diverge sharply on predestination (Calvin's double predestination vs. Luther's more moderate view) and the Eucharist (real presence vs. spiritual presence). FRQs on Protestant diversity often hinge on these distinctions.


Free Church Traditions: Congregational Autonomy and Believer's Choice

These denominations reject hierarchical authority structures and emphasize the local congregation as the primary unit of church life. Individual faith and voluntary commitment take precedence over inherited religious identity.

Baptists

  • Believer's baptism by immersion—only those who personally profess faith are baptized, rejecting infant baptism as theologically meaningless
  • Congregational autonomy—each local church governs itself independently, with no bishops or denominational hierarchy holding authority over congregations
  • Separation of church and state—Baptists historically championed religious liberty, influencing the First Amendment's establishment clause

Methodists

  • Prevenient grace—God's grace works in all people before conversion, enabling genuine free will in accepting or rejecting salvation
  • Personal holiness and social justice form twin emphases, connecting individual spiritual growth to concrete action in the world
  • Connectionalism—while valuing local churches, Methodists maintain denominational structures (conferences, bishops) that link congregations together

Compare: Baptists vs. Methodists—both are Protestant and emphasize personal faith, but they differ fundamentally on church governance (congregational autonomy vs. connectional structure) and theology of grace (Baptist emphasis on individual decision vs. Methodist prevenient grace enabling that decision).


Spirit-Centered Traditions: Experience and Renewal

These movements prioritize direct experience of the divine, often through emotional worship, spiritual gifts, and personal transformation. They represent Christianity's most rapidly growing segment globally.

Pentecostalism

  • Baptism of the Holy Spirit—understood as a distinct experience after conversion, often evidenced by speaking in tongues (glossolalia)
  • Spiritual gifts including healing, prophecy, and miracles are expected as normal parts of Christian life, not historical relics
  • Expressive worship features contemporary music, spontaneous prayer, and physical demonstrations of faith, contrasting sharply with liturgical traditions

Evangelicalism

  • Personal conversion (being "born again") serves as the defining mark of authentic faith, emphasizing a conscious decision to follow Christ
  • Biblical authority—scripture is the final word on faith and practice, typically interpreted more literally than in mainline Protestant traditions
  • Activist faith—strong emphasis on evangelism, missions, and engagement with social/political issues based on biblical principles

Compare: Pentecostalism vs. Evangelicalism—both emphasize personal experience and biblical authority, but Pentecostals specifically stress ongoing supernatural gifts while broader evangelicalism may or may not embrace charismatic practices. Many Pentecostals identify as evangelical, but not all evangelicals are Pentecostal.

Self-Check Questions

  1. Which two denominations both claim apostolic succession but disagree on papal authority, and what historical event formalized their split?

  2. A denomination emphasizes believer's baptism, congregational governance, and separation of church and state. Which tradition does this describe, and what theological principle unifies these positions?

  3. Compare and contrast Lutheran and Calvinist views on salvation—what do they share as Reformation traditions, and where do they diverge on predestination and the Eucharist?

  4. If an FRQ asks you to explain how different Christian traditions locate religious authority, which three sources would you discuss for Anglicanism, and how does this differ from Baptist approaches?

  5. What distinguishes Pentecostalism from broader evangelicalism, and why might a scholar classify Pentecostalism as a subset of the evangelical movement?
