Developing Christian Belief and Practice
Welcome to your study notes for AS 4: The Origins and Development of the Early Christian Church to AD 325. In this chapter, we explore how the early Christians went from a small, informal movement to a structured, united Church with clear rituals, leadership, and statements of belief. Don't worry if the ancient terms feel unfamiliar at first—we will break down every source and concept step by step!
Why does this chapter matter?
Between the death of Jesus and the Council of Nicaea in AD 325, Christianity faced massive challenges: internal divisions, confusing heresies, and external pressure from the Roman Empire. To survive and remain faithful, the Church had to define its sacraments (sacred rites), its leadership structure, and its creeds (statements of faith).
1. Christian Initiation: The Sacrament of Baptism
A. Meaning and Theological Foundations
In the earliest days, Christian baptism grew out of Jewish ritual washings and John the Baptist's baptism of repentance. However, the early Christian Church quickly developed a deeper theological understanding of the rite:
• Remission of Sins: Baptism washed away past sins.
• Regeneration by the Holy Spirit: The believer was spiritually reborn into a new life.
• Dying and Rising with Christ: Influenced by Pauline theology, going under the water symbolised being buried with Christ, and emerging symbolised rising to new resurrection life.
• Incorporation: The person officially became a member of the "Body of Christ" (the Church).
B. Preparation and Practice: The Didache (Chapter 7)
As the Church grew, baptism was no longer an instant event. Candidates had to undergo a period of instruction known as catechesis to learn the faith and prove their sincere commitment.
Primary Source Spotlight: The Didache
Written in the late 1st or early 2nd century, the Didache (also called the Teaching of the Twelve Apostles) gives us our earliest surviving "instruction manual" for Christian rituals. In Chapter 7, it sets out clear baptismal rules:
• Preparation: Both the baptiser and the person being baptised were instructed to fast for one or two days beforehand.
• The Formula: Baptism must be conducted using the Trinitarian formula: "In the name of the Father, and of the Son, and of the Holy Spirit."
• Type of Water: Living (running/flowing) cold water was preferred. If running water was unavailable, still cold water could be used. If cold water was unavailable, warm water was permitted.
• Affusion (Pouring): If there was not enough water for full immersion, pouring water over the head three times in the name of the Trinity was entirely acceptable.
Memory Tip for the Didache's Water Hierarchy:
Think Running Cold \(\rightarrow\) Still Cold \(\rightarrow\) Warm \(\rightarrow\) Pouring 3 Times. The early Church was practical when water was scarce!
Key Takeaway: Baptism
Baptism was the non-negotiable entry rite into the Church. It shifted from simple immersion to a carefully prepared sacrament governed by strict Trinitarian wording and practical liturgical rules found in the Didache.
2. The Eucharist and the Separation from the Agape Meal
A. Meaning and Theology
The central weekly act of early Christian worship was the Eucharist (from the Greek eucharistia, meaning "thanksgiving"), also known as the Lord's Supper. It represented:
• Thanksgiving: A joyful prayer of gratitude for creation and redemption.
• New Covenant: Commemorating the sacrifice of Christ's body and blood as instituted at the Last Supper.
• Koinonia (Fellowship): A tangible expression of unity, sharing one bread and one cup as an equal family.
B. Separation from the Agape Meal
Originally, the Eucharist took place as part of a full communal meal known as the Agape (Love-Feast). Over the course of the 1st and 2nd centuries, the two events were separated. Why did this happen?
• Practical Abuses: Some members overate or arrived early and excluded the poor, destroying the sacred meaning of the meal.
• Roman Suspicion: Roman authorities looked suspiciously upon secretive evening banquets. The correspondence between Emperor Trajan and Pliny the Younger highlights Roman bans on illicit club meetings (hetaeriae). To avoid false accusations of cannibalism, disorder, or treason, Christians moved their sacred Eucharistic rite to the early morning and detached it from the evening social feast.
C. 2nd-Century Liturgy: Justin Martyr (First Apology, Ch. 65–67)
Writing around AD 150 to the Roman Emperor, Justin Martyr defended Christians against false rumours by describing exactly what happened during Sunday worship.
Step-by-Step Order of Early Christian Worship (Justin Martyr):
1. Gathering on the "Day of the Sun" (Sunday): Christians met on Sunday because it was the day of Christ's resurrection and the first day of creation.
2. Liturgy of the Word: Readings were taken from the "memoirs of the Apostles" (Gospels) or the writings of the Prophets for as long as time permitted.
3. The Homily (Sermon): The president (leader) gave a verbal exhortation encouraging everyone to imitate these noble teachings.
4. Prayers of Intercession: The congregation stood and prayed together for themselves, for the newly baptised, and for all people everywhere.
5. The Kiss of Peace: A holy greeting expressing mutual reconciliation and love.
6. Presentation of Elements: Bread and a cup of wine mixed with water were brought to the president.
7. The Eucharistic Prayer: The president offered praise, glory, and thanksgiving to the Father through the Son and Holy Spirit. The prayers were heartfelt and extended.
8. The "Amen": The entire congregation affirmed the prayer by shouting "Amen" (Hebrew for "so be it").
9. Distribution & Pastoral Care: The deacons distributed the consecrated bread and wine to everyone present and carried portions to those who were absent or sick.
Key Takeaway: The Eucharist
Justin Martyr reveals a structured, dignified, and public-facing liturgy. The separation from the evening Agape meal safeguarded the solemnity of the sacrament and protected the community from Roman political suspicion.
3. Development of Church Authority and Ministry
A. From Charismatic Gifts to Institutional Structure
In the earliest decades of the Church, leadership was largely charismatic and itinerant (travelling). Communities relied on wandering apostles, prophets, and teachers who were moved by the Holy Spirit. However, as the original apostles died and false teachers emerged, the Church required local, permanent, and institutional leadership.
This led to the establishment of the Three-Fold Ministry:
1. Episkopos (Bishop / Overseer): The single chief leader of a local church, holding primary administrative, pastoral, and sacramental authority.
2. Presbyteros (Presbyter / Elder / Priest): Local leaders assisting the bishop, teaching, and leading smaller house gatherings.
3. Diakonos (Deacon / Servant): Officers responsible for practical service, caring for the poor, and assisting during the liturgy (such as distributing the elements).
B. Monepiscopacy: Ignatius of Antioch (c. AD 110)
Monepiscopacy (the rule of a single "Monarchical" Bishop over a city or community) became the universal model of Church government. Its greatest champion was Ignatius of Antioch.
While travelling to Rome to be martyred, Ignatius wrote letters to various churches emphasising two central themes:
• Safeguard Against Heresy: False teachings like Docetism (the belief that Jesus only appeared to have a physical body) and early forms of Gnosticism were dividing the Church. Ignatius argued that staying loyal to the single Bishop was the only guaranteed way to preserve orthodox (correct) truth.
• Unity and Sacramental Validity: Ignatius insisted: "Let nothing be done concerning the Church without the Bishop." A Baptism or Eucharist was only valid and acceptable to God if authorised or presided over by the Bishop.
Analogy to remember Monepiscopacy:
Think of the Bishop as an anchor in a storm. In a sea of conflicting ideas and persecution, the Bishop kept the local congregation anchored to true apostolic tradition.
Key Takeaway: Church Authority
The Church shifted from flexible, travelling ministries to a fixed Three-Fold Order (Bishop, Presbyter, Deacon). Monepiscopacy, championed by Ignatius, provided the doctrinal stability and sacramental order needed to preserve unity.
4. Confessions of Faith and Early Creeds
A. The Evolution of Creeds
Why did early Christians write creeds? Creeds were not dry academic tests; they were essential summaries of belief used for baptism, teaching, and refuting heresies.
• Earliest Stage: Simple Confessions: The earliest New Testament confession was simply "Jesus is Lord" (a radical statement in an Empire that demanded worship of Caesar).
• Second Stage: Baptismal Interrogatories: As seen in Hippolytus' Apostolic Tradition, baptismal candidates were asked three direct questions while standing in the water: "Do you believe in God the Father Almighty? Do you believe in Christ Jesus, the Son of God...? Do you believe in the Holy Spirit...?" To each question, the candidate replied, "I believe," and was immersed.
• Third Stage: Proto-Creeds and Rules of Faith: Expanded summaries were developed to counter heretical movements like Marcionism (which rejected the Old Testament God) and Gnosticism (which rejected the real human flesh of Christ).
• Fourth Stage: Ecumenical Creeds: This progression culminated in the universal settlement of the Council of Nicaea (AD 325), which established a definitive, binding creed for all Christians across the Roman world.
Key Takeaway: Creeds
Creeds developed organically: starting as brief baptismal vows, expanding into defensive summaries of orthodoxy, and finally becoming universal doctrinal standards at Nicaea.
5. Exam Skills and Avoiding Pitfalls
Understanding the Assessment Objectives
• AO1 (Knowledge and Understanding): Show detailed knowledge of primary texts (Didache 7, Justin Martyr's First Apology 65–67, Ignatius' letters). Use technical Greek terms accurately (episkopos, presbyteros, diakonos, eucharistia, koinonia).
• AO2 (Evaluation & Human Experience): Weigh up historical debates and link them to broader questions. For example: Was a strict hierarchy necessary for survival, or did it stifle the Spirit? How do these early rituals continue to shape Christian life and corporate identity today?
Common Pitfalls to Avoid
• Anachronism: Do not describe 2nd-century worship using modern denominational terms (e.g. talking about modern Protestant or Roman Catholic systems). Keep your answers rooted in the 1st to 4th centuries.
• Vague Generalities: Never write "they had bread and wine and prayed." Always quote or cite Justin Martyr or the Didache specifically.
• Confusing Ministry Terms: In the earliest New Testament texts, episkopos (overseer) and presbyteros (elder) were often used interchangeably. Make sure you explain how Ignatius of Antioch helped establish the distinct, monarchical role of the single Bishop (monepiscopacy).
