- 1st Epistle of Clement to the Corinthians [ca 96]: A formal letter written on behalf of the Roman Christian community urging Christians who had been rebelling against church authority to be submissive and obedient. Tradition attributes it to Clement, allegedly one of the first bishops of Rome.
- 2nd Epistle of Clement to the Corinthians [ca 150]: Sermon thought not to be the writing of Clement himself. Advocates sound view of Christ, the resurrection, and holiness unto God. Enter into battle against the ways of this world, work out salvation through strength in Christ.
- The Epistle of Barnabas [ca 130]: This letter, probably not authored by the NT Barnabas, repudiates the claims of Jewish Christians at the time who advocated adhering to observance of the Mosiac Law. Argued that Christ provided salvation and man is no longer bound by the Law. Compares holy life to unrighteousness. The last part of this treatise consists of a form of the Two Ways Teaching also found at the start of the Didache.
- Didache (Teaching of the Lord through the Apostles): Eleventh century MS discovered by Philotheus Bryennios. The Didache consists of various parts, starting with the “Two Ways” ethical instruction (see Barn 18-21) and including community rules for liturgical practices and leadership conduct, before ending with a short apocalyptic section. While some of the material might go back before the year 100, the current form of the document is probably mid-second century at earliest.
- The Shepherd of Hermas [ca. 150]: Written by Hermas, who is believed to be brother of Pius, the Bishop of Rome. The Shepherd of Hermas is an apocalyptic document (in the sense that it claims to be revealed), modelled after the Book of Revelation. It deals with practical matters of church purity and discipline in second century Rome.
- The Epistle of Polycarp to the Philippians [ca 130?]: Polycarp was a church leader (bishop) in Smyrna, Asia Minor. Exhorted the Philippians to holy living, good works, steadfast faith. Interested in ministry and practical aspects of daily life of Christians.
- The Martyrdom of Polycarp: The earliest preserved Christian martyrology, probably from the latter part of the second century (not too long after the event). Records the tradition of the trial and execution (burned at the stake) of Polycarp.
- The Writings of Ignatius: Bishop of Antioch in Syria [ca 1-2 century] martyred in Rome by beasts (ca 105-116). On his way to Rome, he visits and then writes to various churches, warning and exhorting them. He also writes ahead to Rome, and writes to Polycarp, bishop of Smyrna. Warned the church against heresies that threatened peace and unity, opposed Gnosticism and Docetism. In the Epistle to Smyrna, insisted Christ came in the flesh not just in spirit.
- The Epistle of Mathetes (Believer/Disciple) to Diognetus: This Apologetic treatise? written perhaps ca 200, presents a rational defense of Christianity and shows the folly of idolatry. The document also discusses Christian influence in the world.
- The Writings of Tertullian: Our earliest extensively preserved Latin Christian author [140-230], who aligned himself around 207 with the “Montanist” Christian movement that was considered “heretical” by the representatives of emerging mainstream Christianity.

THIS WEEKS SELECTION OF DOCUMENTS FROM THE INDEX
The Letter to Diognetus: What do we know about it? (Church Fathers)
The anonymous Epistle to Diognetus [die-og-NEE-tus] is “one of the most beautiful and noble defenses of the [Christian] faith” in the early second century AD. It is, by nature, an early apologetic work.
Apostolic and Pre-Nicene Eras
AD 29-33: Jesus is crucified, rises again, and the church begins at Pentecost.
33-100: Apostolic era; independent churches spread around the Roman empire and beyond.
100-303: Church expands beyond empire; suffering persecution fuels more growth. The church becomes more organized, and the clergy becomes more important and powerful.
Great Persecution and Rise of Constantine to Power
AD 303-311: Galerius leads two Augusti and two Caesars in the Great Persecution of Christians.
311: Galerius signs the Edict of Toleration, ending persecution, and admits failure.
311: Galerius dies from a disease that Christians attribute to the judgment of God.
312: Constantine has a vision of a Christian symbol similar to the cross, and inscribes the symbol on the shields of soldiers, and defeats Maxentius to unite the western empire.
Events Leading to Council of Nicaea
AD 268-312: Lucian, an elder in Antioch, heads a theological school that trained early leaders of Arianism. Lucian dies as a martyr in communion with the church in 312.
318: Arius, an elder in Alexandria, tells Bishop Alexander the Son did not exist before God in the beginning.
321: Arius is excommunicated by the council of bishops and moves to Nicomedia, where he is welcomed by Eusebius.
321-325: Arius and Eusebius teach their doctrine to sailors, merchants, and children, and write letters to other bishops trying to spread the Arian belief.
324: Constantine defeats and then executes Licinius, and unites the entire Roman Empire under his rule.
325: Constantine offers transportation to all bishops to come to Nicaea for a council to resolve the Arian controversy.
Council of Nicaea and Afterward
AD 325: Council of Nicaea is held in the summer. Arius is banished along with Theonas and Secundus.
325-326: Eusebius of Nicomedia and Theognis of Nicaea are banished (probably).
328: Eusebius and Theognis write a letter of recantation, stating Arius also has been received back from exile. Constantine restores them to their cleric positions.
328-335: Constantine orders the church in Alexandria to talk with Arius; Athanasius refuses.
335: Council of Tyre, led by Eusebius of Nicomedia and Theognis of Nicaea, attempts to convict Athanasius of various crimes but fails. Constantine calls major bishops to Constantinople, then expels Athanasius.
336: A council in Jerusalem restores Arius but he dies on the way to Constantinople for his first communion and his banishment. Supporters say he was poisoned; opponents say he was judged by God.
337: Constantine is baptized by Eusebius of Nicomedia, dies several days later, and leaves the empire to his three sons: Constantine II, Constans, and Constantius. Constantine II sends Athanasius back to Alexandria.
337-361: Constantius, emperor in the east, embraces Arianism, installs Arian bishops in many cities of the east, resulting in general pandemonium.
339: Eusebius of Caesarea, known as the father of church history, dies.
341: Constantius brings Eusebius from Nicomedia to Constantinople. Eusebius calls a council in Antioch to affirm a new creed and expel Athanasius from Alexandria. Western bishops reject the creed.
343: A council is called in Sardica to reconcile east and west. A controversy over Paul and Athanasius, rejected from their sees, causes the eastern bishops to hold their own council in Philippopolis. Sardica confirms homoousios, but it is rejected in Philippopolis, and east and west are completely divided.
347-348: Constans threatens Constantius with civil war if he does not reinstall Paul and Athanasius as bishops. Constantius agrees and orders their cities to support them.
348: (Approximate date) Athanasius calls a council in Jerusalem, and two leading Arian bishops–Ursacius and Valens–temporarily embrace the Nicene Creed. Athanasius then alienates most eastern bishops and Constantius by appointing elders in other jurisdictions.
350-361: Constantius overthrows Magnentius, then tries to spread Arianism in the west. He removes bishops in the west and the east, replacing them with bishops espousing Arian opinions.
356: Liberius, bishop of Rome, is banished, and Athanasius is forced to flee Alexandria for his life.
358: Liberius is restored to his position after signing a creed with Arian sentiments under duress.
359: Council of Ariminum is held in the west and Council of Seleucia in the east. Both councils approve an Arian creed, but numerous bishops, especially in the west, object. Jerome later mourns that at this point, “The world groaned and was astonished to find itself Arian.”
361: Constantius dies, and Julian the Apostate becomes emperor in the east. He embraces paganism and recalls all the
bishops Constantius banished, perhaps hoping the Christians will battle each other into extinction, He also introduces persecution against Christians.
363: Julian is killed in battle with the Persians, and Jovian becomes emperor. Jovian supports the Nicene Creed without violence, bringing growing peace to the east, but he dies of illness after seven months. The Acacian sect of Arians embraces the Nicene Creed.
364: Valens becomes emperor in the east, embraces Arianism, persecutes the Nicene churches, and attempts to install Arian bishops in all eastern churches. Valentinian I becomes emperor in the west and holds to the Nicene Creed.
375: Barbarian Goths kill Valentinian, emperor in the west.
375: Gratian, a nephew of Valens, becomes emperor in the west and supports the Nicene Creed.
375: Valens defeats the Goths, gives them mercy, and they embrace Christianity, becoming Arians. Barbarian tribes remain Arians for at least a century.
378: Valens is slain in another battle with the Goths.
378-381: Gratian recalls all banished Nicene bishops in the east, but allows various sects to worship unmolested in their own churches.
379: Gratian appoints Theodosius as emperor in the east to replace Valens.
381: Theodosius calls a council in Constantinople to affirm a modified Nicene Creed. 150 bishops arrive from the east, plus Macedonian bishops whom the emperor wished to convert–but they refuse and leave the meeting. This council becomes remembered as the “Second Ecumenical Council of the Church.”
383: Theodosius requests a defense of the faith from all four major sects. After much prayer and consideration, he decides on the homoousian party. This event ended the Arian controversy and constituted the final victory for the Nicene Creed. Arianism does not disappear but is considered unorthodox and outside the faith of the church.
