The Origins and Development of the Early Christian Church to AD 325

Area 2: Systematic Study of One Religion · Unit AS 4 (AS level)

This mini-lesson covers Unit AS 4: The Origins and Development of the Early Christian Church to AD 325 — the growth and persecution of the Church, the development of baptism and the Eucharist, the writings of Ignatius of Antioch and Justin Martyr, and the reign of Constantine up to the Council of Nicaea.

Expanding the faith

How did a small Jewish movement become an empire-wide faith within three centuries? Candidates weigh the religious and political factors behind the growth of the Early Church.

Paradoxically, martyrdom fuelled expansion. The specification names three examples:

  • Blandina, a slave girl martyred at Lyons;
  • Justin (Justin Martyr); and
  • Polycarp, bishop of Smyrna.

The witness of martyrs, whose Greek name martys means 'witness', became a powerful testimony to the faith.

Learning focus

Persecution

The causes and effects of persecution changed over time:

  • First two centuries — local and sporadic, under Nero, Domitian, Trajan (see Pliny's Letter to Trajan) and Marcus Aurelius; and
  • Later persecutions — empire-wide and systematic, under Decius and Diocletian.

Pliny, a Roman governor, wrote to the Emperor Trajan asking how to deal with Christians — a key piece of external evidence for how the state viewed the Church.

1Pliny's Letter to Trajan is important to this unit because it:
Learning focus

Developing belief and practice: baptism

The doctrine and practice of baptism grew from its origins in the New Testament. The specification tracks its development through five early witnesses:

  • the Didache (an early church manual);
  • Justin Martyr;
  • Hippolytus;
  • Tertullian; and
  • Cyprian.
Learning focus

The Eucharist

The Eucharist likewise developed from its New Testament origins. Candidates trace its doctrine and practice through the same set of writers — the Didache, Justin, Hippolytus, Tertullian and Cyprian — noting how understanding of the sacrament deepened across the period.

2Which set of early sources does the specification use to trace the development of baptism and the Eucharist?
Learning focus

Ignatius of Antioch

Ignatius of Antioch was one of the Apostolic Fathers. On his journey to martyrdom in Rome he wrote seven letters — to the Ephesians, Magnesians, Philadelphians, Romans, Smyrnaeans, Trallians and to Polycarp.

Their key themes are:

  • unity and obedience to the bishop;
  • opposition to heresy and to the Judaisers; and
  • the glory of martyrdom.

Justin Martyr

Justin Martyr represents the apologists — thinkers who defended the faith to a hostile, educated world. His writings are:

  • the First Apology;
  • the Second Apology; and
  • the Dialogue with Trypho the Jew.

His arguments are political, moral, philosophical and theological — showing Christianity to be reasonable, virtuous and the fulfilment of truth.

3Which works are associated with Justin Martyr in this unit?
Learning focus

The Church and the State: Constantine

The final theme examines the relationship between Church and state through the Emperor Constantine:

  • events leading to his 'conversion' (the quotation marks flag the scholarly debate over how genuine or political it was);
  • his subsequent religious policies; and
  • the Council of Nicaea (AD 325) — the point at which the unit closes.

Under Constantine the Church moved from a persecuted minority to an imperially favoured institution — a transformation candidates should critically evaluate.
