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.
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.
Saint PeterSaint Peter (died between AD 64 and 68), also known as Peter the Apostle, Simon Peter, Simeon, Simon, or Cephas ( () 'rock'), was one of the Twelve Apostles of Jesus Christ and one of the first leaders of the early Christian Church. He appears repeatedly and prominently in all four New Testament gospels as well as the Acts of the Apostles. According to Christian tradition, Peter was crucified in Rome under Emperor Nero.
NovatianismNovatianism or Novationism was an early Christian sect devoted to the theologian Novatian ( 200–258) that held a strict view that refused readmission to communion of lapsi (those baptized Christians who had denied their faith or performed the formalities of a ritual sacrifice to the pagan gods under the pressures of the persecution sanctioned by Emperor Decius in AD 250). The Church of Rome declared the Novatianists heretical following the letters of Saint Cyprian of Carthage and Ambrose wrote against them.
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.
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.
Believer's baptismBeliever's baptism or adult baptism (occasionally called credobaptism, from the Latin word credo meaning "I believe") is the practice of baptizing those who are able to make a conscious profession of faith, as contrasted to the practice of baptizing infants. Credobaptists believe that infants incapable of consciously believing should not be baptized. The mode of believer's baptism depends on the Christian denomination, and is done either by pouring (the normative method in Mennonite, Amish, and Hutterite churches) or by immersion (the normative method practiced by Schwarzenau Brethren, River Brethren, Baptists, and the Churches of Christ, among others).
Persecution of ChristiansThe persecution of Christians can be historically traced from the first century of the Christian era to the present day. Christian missionaries and converts to Christianity have both been targeted for persecution, sometimes to the point of being martyred for their faith, ever since the emergence of Christianity. Early Christians were persecuted at the hands of both Jews, from whose religion Christianity arose, and the Romans who controlled many of the early centers of Christianity in the Roman Empire.
Catacombs of RomeThe Catacombs of Rome (Catacombe di Roma) are ancient catacombs, underground burial places in and around Rome, of which there are at least forty, some rediscovered only in recent decades. Though most famous for Christian burials, either in separate catacombs or mixed together, Jews and also adherents of a variety of pagan Roman religions were buried in catacombs, beginning in the 2nd century AD, occasioned by the ancient Roman ban on burials within a city, and also as a response to overcrowding and shortage of land.
RelicIn religion, a relic is an object or article of religious significance from the past. It usually consists of the physical remains or personal effects of a saint or other person preserved for the purpose of veneration as a tangible memorial. Relics are an important aspect of some forms of Buddhism, Christianity, Islam, shamanism, and many other religions. Relic derives from the Latin reliquiae, meaning "remains", and a form of the Latin verb relinquere, to "leave behind, or abandon".
