Barnabas, born Joseph (Ἰωσήφ) or Joses (Ἰωσής), was according to tradition an early Christian, one of the prominent Christian disciples in Jerusalem. According to Acts 4:36, Barnabas was a Cypriot Levite. Named an apostle in Acts 14:14, he and Paul the Apostle undertook missionary journeys together and defended Gentile converts against the Judaizers. They traveled together making more converts, and participated in the Council of Jerusalem. Barnabas and Paul successfully evangelized among the "God-fearing" Gentiles who attended synagogues in various Hellenized cities of Anatolia.
The word catholic comes from the Greek phrase καθόλου 'on the whole, according to the whole, in general', and is a combination of the Greek words κατά 'about' and ὅλος 'whole'. The first known use of "Catholic" was by the church father Saint Ignatius of Antioch in his Letter to the Smyrnaeans. In the context of Christian ecclesiology, it has a rich history and several usages.
Ignatius of Antioch, also known as Ignatius Theophorus, was an early Christian writer and Patriarch of Antioch. While en route to Rome, where he met his martyrdom, Ignatius wrote a series of letters. This correspondence forms a central part of a later collection of works by the Apostolic Fathers. He is considered one of the three most important of these, together with Clement of Rome and Polycarp. His letters also serve as an example of early Christian theology, and address important topics including ecclesiology, the sacraments, and the role of bishops.
Polycarp 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 Eastern Orthodox Church, Roman Catholic Church, Oriental Orthodox Churches, Lutheranism, and Anglicanism.
The Patriarch of Alexandria is the archbishop of Alexandria, Egypt. Historically, this office has included the designation "pope".
An apostolic see is an episcopal see whose foundation is attributed to one or more of the apostles of Jesus or to one of their close associates. In Catholicism, the phrase "The Apostolic See" when capitalized refers specifically to the See of Rome.
The 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.
The purpose of this timeline is to give a detailed account of Christianity from the beginning of the current era (AD) to the present. Question marks ('?') on dates indicate approximate dates.
The seventy disciples, known in the Eastern Christian traditions as the seventy apostles, were early emissaries of Jesus mentioned in the Gospel of Luke. The number of those disciples varies between either 70 or 72 depending on the manuscript.
Martyrdom of Polycarp is a manuscript written in the form of a letter that relates the religious martyrdom of Polycarp, Bishop of Smyrna and disciple of John the Apostle in the 2nd century AD. It forms the earliest account of Christian martyrdom outside of the New Testament. The author of Martyrdom of Polycarp is unknown, but it has been attributed to members of the group of early Christian theologians known as the Church Fathers. The letter, sent from the church in Smyrna to another church in Asia Minor at Philomelium, is partly written from the point of view of an eye-witness, recounting the arrest of the elderly Polycarp, the Romans' attempt to execute him by fire, and subsequent miraculous events.
The Patrologia Graeca is an edited collection of writings by the Church Fathers and various secular writers, in the Greek language. It consists of 161 volumes produced in 1857–1866 by J.P. Migne's Imprimerie Catholique, Paris.
The term proto-orthodox Christianity or proto-orthodoxy describes the early Christian movement that was the precursor of Christian orthodoxy. Older literature often referred to the group as "early Catholic" in the sense that their views were the closest to those of the more organized Catholic Church of the 4th and 5th centuries. The term "proto-orthodox" was coined by Bentley Layton, a scholar of Gnosticism and a Coptologist at Yale, but is often attributed to New Testament scholar Bart D. Ehrman, who has popularized the term by using it in books for a non-academic audience. Ehrman argues that when this group became prominent by the end of the third century, it "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'."
The doctrine of the Trinity, considered the core of Christian theology by Trinitarians, is the result of continuous exploration by the church of the biblical data, thrashed out in debate and treatises, eventually formulated at the First Council of Nicaea in AD 325 in a way they believe is consistent with the biblical witness, and further refined in later councils and writings. The most widely recognized Biblical foundations for the doctrine's formulation are in the Gospel of John, which possess ideas reflected in Platonism and Greek philosophy.
Christianity 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 following outline is provided as an overview of and topical guide to Christianity:
Early Christianity, otherwise called the Early Church or Paleo-Christianity, 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 throughout the Eastern Mediterranean. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians, as well as Phoenicians, i.e. Lebanese Christians. Early Christianity contains the Apostolic Age and is followed by, and substantially overlaps with, the Patristic era.
The canon of the New Testament is the set of books many modern Christians regard as divinely inspired and constituting the New Testament of the Christian Bible. For most churches, the canon is an agreed-upon list of 27 books that includes the canonical Gospels, Acts, letters attributed to various apostles, and Revelation.
The Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church were ancient and influential Christian theologians and writers who established the intellectual and doctrinal foundations of Christianity. The historical period in which they worked became known as the Patristic Era and spans approximately from the late 1st to mid-8th centuries, flourishing in particular during the 4th and 5th centuries, when Christianity was in the process of establishing itself as the state church of the Roman Empire.
Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus as interpreted in the Bible. It is the largest religion in the world, with 2.4 billion people, known as Christians, that adhere to the religion.
