Christianity in the 1st centuryChristianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (27–29 AD) to the death of the last of the Twelve Apostles (100) and is thus also known as the Apostolic Age. Early Christianity developed out of the eschatological ministry of Jesus. Subsequent to Jesus' death, his earliest followers formed an apocalyptic messianic Jewish sect during the late Second Temple period of the 1st century.
Christian theologyChristian theology is the theology of Christian belief and practice. Such study concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument.
New Testament apocryphaThe New Testament apocrypha (singular apocryphon) are a number of writings by early Christians that give accounts of Jesus and his teachings, the nature of God, or the teachings of his apostles and of their lives. Some of these writings were cited as scripture by early Christians, but since the fifth century a widespread consensus has emerged limiting the New Testament to the 27 books of the modern canon. Roman Catholic, Eastern Orthodox, and Protestant churches generally do not view the New Testament apocrypha as part of the Bible.
Christianity in the ante-Nicene periodChristianity in the ante-Nicene period was the time in Christian history up to the First Council of Nicaea. This article covers the period following the Apostolic Age of the first century, c. 100 AD, to Nicaea in 325 AD. The second and third centuries saw a sharp divorce of Christianity from its early roots. There was an explicit rejection of then-modern Judaism and Jewish culture by the end of the second century, with a growing body of adversus Judaeos literature.
Biblical canonA biblical canon is a set of texts (also called "books") which a particular Jewish or Christian religious community regards as part of the Bible. The English word canon comes from the Greek κανών kanōn, meaning "rule" or "measuring stick". The use of the word "canon" to refer to a set of religious scriptures was first used by David Ruhnken, in the 18th century. Various biblical canons have developed through debate and agreement on the part of the religious authorities of their respective faiths and denominations.
Apostles in the New TestamentIn Christian theology and ecclesiology, the apostles, particularly the Twelve Apostles (also known as the Twelve Disciples or simply the Twelve), were the primary disciples of Jesus according to the New Testament. During the life and ministry of Jesus in the 1st century AD, the apostles were his closest followers and became the primary teachers of the gospel message of Jesus. There is also an Eastern Christian tradition derived from the Gospel of Luke of there having been as many as seventy apostles during the time of Jesus' ministry.
Jewish ChristianJewish Christians were the followers of a Jewish religious sect that emerged in Judea during the late Second Temple period (first century AD). These Jews believed Jesus to be the prophesied Messiah, but maintained the observance of Jewish law. Jewish Christianity is the foundation of Early Christianity, which later developed into Catholic and Eastern Orthodox Christianity. Christianity started with Jewish eschatological expectations, and it developed into the worship of Jesus after his earthly ministry, his crucifixion, and the post-crucifixion experiences of his followers.
PolycarpPolycarp (ˈpɒlikɑːrp; Πολύκαρπος, Polýkarpos; Polycarpus; AD 69 155) was a Christian bishop of Smyrna. According to the Martyrdom of Polycarp, he died a martyr, bound and burned at the stake, then stabbed when the fire failed to consume his body. Polycarp is regarded as a saint and Church Father in the Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and Lutheran churches. Both Irenaeus and Tertullian say that Polycarp had been a disciple of John the Apostle, one of Jesus' disciples.
CatechismA catechism (pronˈkætəˌkɪzəm; from κατηχέω, "to teach orally") is a summary or exposition of doctrine and serves as a learning introduction to the Sacraments traditionally used in catechesis, or Christian religious teaching of children and adult converts. Catechisms are doctrinal manuals – often in the form of questions followed by answers to be memorised – a format that has been used in non-religious or secular contexts as well.
Early ChristianityEarly Christianity, or Paleochristianity, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians. Early Christianity contains the Apostolic age and is followed by, and substantially overlaps with, the Patristic era.
