Proto-orthodox ChristianityThe term proto-orthodox Christianity or proto-orthodoxy describes the early Christian movement that was the precursor of Christian orthodoxy. It was coined by Bentley Layton (a major scholar of Gnosticism and Coptologist at Yale), but is often erroneously attributed to New Testament scholar Bart D. Ehrman. Ehrman argues that this group from the moment it became prominent by the end of the third century, "stifled its opposition, it claimed that its views had always been the majority position and that its rivals were, and always had been, 'heretics', who willfully 'chose' to reject the 'true belief'.
CatechesisCatechesis (ˌkætəˈkiːsɪs; from Greek: κατήχησις, "instruction by word of mouth", generally "instruction") is basic Christian religious education of children and adults, often from a catechism book. It started as education of converts to Christianity, but as the religion became institutionalized, catechesis was used for education of members who had been baptized as infants.
Aniconism in ChristianityAniconism is the absence of material representations of the natural and supernatural world in various cultures, particularly in the monotheistic Abrahamic religions. Most denominations of Christianity have not generally practiced aniconism, or the avoidance or prohibition of types of images, even dating back to early Christian art and architecture. Those in the faith have generally had an active tradition of making artwork and Christian media depicting God, religious figures, and other aspects of theology.
Catholic (term)The word catholic (derived via Late Latin catholicus, from the ancient Greek adjective καθολικός () ) comes from the Greek phrase καθόλου () , and is a combination of the Greek words κατά () and ὅλος () . The first known use of "Catholic" was by the church father Saint Ignatius of Antioch in his Letter to the Smyrnaeans (circa 110 AD). In the context of Christian ecclesiology, it has a rich history and several usages. The word in English can mean either "of the Catholic faith" or "relating to the historic doctrine and practice of the Western Church".
Apostolic ConstitutionsThe Apostolic Constitutions or Constitutions of the Holy Apostles (Latin: Constitutiones Apostolorum) is a Christian collection divided into eight books which is classified among the Church Orders, a genre of early Christian literature, that offered authoritative pseudo-apostolic prescriptions on moral conduct, liturgy and Church organization. The work can be dated from 375 to 380 AD. The provenance is usually regarded as Syria, probably Antioch.
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.
Christianity in the 5th centuryIn the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God.
Papal primacyPapal primacy, also known as the primacy of the bishop of Rome, is a ecclesiological doctrine in the Catholic Church concerning the respect and authority that is due to the pope from other bishops and their episcopal sees. While the doctrine is accepted at a fundamental level by both the Catholic Church and Eastern Orthodox Church, the two disagree on the nature of primacy. English academic and Catholic priest Aidan Nichols wrote that "at root, only one issue of substance divides the Eastern Orthodox and the Catholic Churches, and that is the issue of the primacy.
Pastoral epistlesThe pastoral epistles are a group of three books of the canonical New Testament: the First Epistle to Timothy (1 Timothy), the Second Epistle to Timothy (2 Timothy), and the Epistle to Titus. They are presented as letters from Paul the Apostle to Timothy and to Titus. They are generally discussed as a group and are given the title pastoral because they are addressed to individuals with pastoral oversight of churches and discuss issues of Christian living, doctrine and leadership. The term "pastorals" was popularized in 1703 by D.
Language of JesusThere exists a consensus among scholars that the language of Jesus and his disciples was Aramaic. Aramaic was the common language of Judea in the first century AD. The villages of Nazareth and Capernaum in Galilee, where Jesus spent most of his time, were Aramaic-speaking communities. Jesus likely spoke a Galilean variant of the language, distinguishable from that of Jerusalem. Based on the symbolic renaming or nicknaming of some of his apostles it is also likely that Jesus and at least one of his apostles knew enough Koine Greek to converse with those not native to Judea.
