Forms of Gnosticism return with Paulicians (800s) and Albigensians (1200s)

QUARTODECIMANISM

c. 155 Polycarp and others from Asia Minor advocate Nisan 14 as date of Easter

c. 190 Pope Victor insists on Sunday observance and tries to stamp out Quartodecimanism (“14th-ism”), though Irenaeus advocates tolerance

In the Middle Ages, the Celtic church (in 625) and the church in Gaul (in the 800s) join the West in adopting the Alexandrian method

MONTANISM

c. 157 Montanus begins prophesying that the Heavenly Jerusalem will soon descend in Phrygia, in Asia Minor

170s Montanism develops ecstatic and ascetic practices

c. 190 Montanism condemned by church councils in Asia Minor

c. 207 Tertullian converts to Montanism

c. 400 Montanism wanes but survives in pockets

Though severly persecuted by Justinian I (483–565), Montanism survives into the 800s

MONARCHIANISM

c. 190s Monarchianism (emphasizing God’s monarchia, “unity”—not the three persons) spreads

c. 200 Noetus condemned at Rome for Patripassianism (“the father suffers-ism”), the teaching that the Father suffered as the Son

268 Council of Antioch deposes Paul of Samosata and condemns Sabellianism (i.e., modalism: Father, Son, and Spirit are temporary manifestations of the same being)

By the early 300s, most Monarchianists become Arians

“PURITANISM”

249–250 Decian persecution causes many Christians to “lapse,” i.e., deny the faith

251 Novatian teaches that the lapsed should not be readmitted to the church; some Christians admit the lapsed on easy terms

252 Cyprian argues for middle view: penance for the lapsed

255–256 African bishops insist on rebaptism of heretics and schismatics; Rome disagrees

311 Donatists refuse to accept new bishop of Carthage because he “handed over” the Scriptures under persecution; they consecrate a rival bishop

314 Council of Arles condemns Donatism, which insists on unwavering loyalty of church members

411 Donatism significantly weakened by government condemnation

Donatism survives in pockets in Africa until Islam conquers the region (late 600s)

ARIANISM

c. 318 Arius’s views, that Jesus is not divine, gains popularity; Athanasius writes On the Incarnation, affirming the full deity and humanity of Jesus

325 Council of Nicea, called by Emperor Constantine, condemns Arians and affirms the divinity of Christ

328–361 Temporary triumph of Arianism; period of factions and confusion; Nicene bishops, like Athanasius, are deposed and banished

c. 340 First conversions of Goths by Arian Ulfilas

361 Valentian, an orthodox, becomes Western emperor, and orthodoxy begins to recover lost ground

381 Theodosius, an orthodox, becomes sole emperor; Council of Constantinople affirms Nicene orthodoxy; Cappadocian Fathers put final touches on Trinitarian doctrine

390s Arianism still alive among the Goths and other Germanic peoples

Arianism disappears in the 700s through gradual conversion to orthodoxy
