Apostolic FathersThe Apostolic Fathers, also known as the Ante-Nicene Fathers, were core Christian theologians among the Church Fathers who lived in the 1st and 2nd centuries AD who are believed to have personally known some of the Twelve Apostles or to have been significantly influenced by them. Their writings, though widely circulated in early Christianity, were not included in the canon of the New Testament. Many of the writings derive from the same time period and geographical location as other works of early Christian literature which came to be part of the New Testament.
Early Christian art and architectureEarly Christian art and architecture or Paleochristian art is the art produced by Christians or under Christian patronage from the earliest period of Christianity to, depending on the definition used, sometime between 260 and 525. In practice, identifiably Christian art only survives from the 2nd century onwards. After 550 at the latest, Christian art is classified as Byzantine, or of some other regional type. It is hard to know when distinctly Christian art began.
Anti-JudaismAnti-Judaism describes a range of historic and current ideologies which are totally or partially based on opposition to Judaism, on the denial or the abrogation of the Mosaic covenant, and the replacement of Jewish people by the adherents of another religion, political theology, or way of life which is held to have superseded theirs as the "light to the nations" or God's chosen people. The opposition is maintained by the appropriation and adaptation of Jewish prophecy and texts, and the stigmatization of the very people who transmitted those texts.
Christian head coveringChristian head covering, also known as Christian veiling, is the traditional practice of women covering their head in a variety of Christian denominations. Some Christian women, based on historic Catholic, Lutheran, Moravian, Reformed, Anglican, Methodist, and Plymouth Brethren teaching, wear the head covering in public worship and during private prayer at home (though some women belonging to these traditions may also choose to wear the head covering outside of prayer and worship), while others, especially traditional Anabaptist Christians, believe women should wear head coverings at all times, based on Saint Paul's dictum that Christians are to "pray without ceasing" (1 Thessalonians 5:17), Saint Paul's teaching that women being unveiled is dishonourable, and as a reflection of the created order.
DidacheThe Didache (ˈdɪdəkeː,_-ki; Didakhé), also known as The Lord's Teaching Through the Twelve Apostles to the Nations (Διδαχὴ Κυρίου διὰ τῶν δώδεκα ἀποστόλων τοῖς ἔθνεσιν), is a brief anonymous early Christian treatise (ancient church order) written in Koine Greek, dated by modern scholars to the first or (less commonly) second century AD. The first line of this treatise is: "The teaching of the Lord to the Gentiles (or Nations) by the twelve apostles".
ValentinianismValentinianism was one of the major Gnostic Christian movements. Founded by Valentinus in the 2nd century AD, its influence spread widely, not just within Rome but also from Northwest Africa to Egypt through to Asia Minor and Syria in the East. Later in the movement's history it broke into an Eastern and a Western school. Disciples of Valentinus continued to be active into the 4th century AD, after the Roman Emperor Theodosius I issued the Edict of Thessalonica (380 AD), which declared Nicene Christianity as the State church of the Roman Empire.
MarcionismMarcionism was an early Christian dualistic belief system that originated with the teachings of Marcion of Sinope in Rome around the year 144. Marcion was an early Christian theologian, evangelist, and an important figure in early Christianity. He was the son of a bishop of Sinope in Pontus. About the middle of the 2nd century (140–155) he traveled to Rome, where he joined the Syrian Gnostic Cerdo.
Christianity and JudaismChristianity began as a movement within Second Temple Judaism, but the two religions gradually diverged over the first few centuries of the Christian Era. Today, differences of opinion vary between denominations in both religions, but the most important distinction is Christian acceptance and Jewish non-acceptance of Jesus as the Messiah prophesized in the Hebrew Bible and Jewish tradition. Early Christianity distinguished itself by determining that observance of halakha (Jewish law) was not necessary for non-Jewish converts to Christianity (See Pauline Christianity).
Acts of PaulThe Acts of Paul is one of the major works and earliest pseudepigraphal series from the New Testament apocrypha also known as Apocryphal Acts. This work is part of a body of literature either about or purporting to be written by Paul the Apostle, including letters, narratives, prayers, and apocalypses. An approximate date given to the Acts of Paul is 100-160 AD. The Acts of Paul were first mentioned by Tertullian, who deemed the work to be heretical because it encouraged women to preach and baptize.
Four Marks of the ChurchThe Four Marks of the Church, also known as the Attributes of the Church, describes four distinctive adjectives of traditional Christian ecclesiology as expressed in the Niceno-Constantinopolitan Creed completed at the First Council of Constantinople in AD 381: "[We believe] in one, holy, catholic, and apostolic Church.
