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.
Simon MagusSimon Magus (Greek Σίμων ὁ μάγος, Latin: Simon Magus), also known as Simon the Sorcerer or Simon the Magician, was a religious figure whose confrontation with Peter is recorded in Acts. The act of simony, or paying for position, is named after Simon, who tried to buy his way into the power of the Apostles. According to Acts, Simon was a Samaritan magus or religious figure of the 1st century AD and a convert to Christianity, baptised by Philip the Evangelist. Simon later clashed with Peter.
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.
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.
Church FathersThe 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.
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.
Pauline epistlesThe Pauline epistles, also known as Epistles of Paul or Letters of Paul, are the thirteen books of the New Testament attributed to Paul the Apostle, although the authorship of some is in dispute. Among these epistles are some of the earliest extant Christian documents. They provide an insight into the beliefs and controversies of early Christianity. As part of the canon of the New Testament, they are foundational texts for both Christian theology and ethics.
Epistle to the EphesiansThe Epistle to the Ephesians is the tenth book of the New Testament. According to its text, the letter was written by Paul the Apostle, an attribution that Christians traditionally accepted. However, starting in 1792, some scholars have claimed the letter is actually Deutero-Pauline, meaning that it is pseudepigrapha written in Paul's name by a later author strongly influenced by Paul's thought. According to one scholarly source, the letter was probably written "by a loyal disciple to sum up Paul's teaching and to apply it to a new situation fifteen to twenty-five years after the Apostle's death".
Valentinus (Gnostic)Valentinus (Greek: Οὐαλεντῖνος), also spelled Valentinius; AD 100 – 180, was the best known and, for a time, most successful early Christian Gnostic theologian. He founded his school in Rome. According to Tertullian, Valentinus was a candidate for bishop but started his own group when another was chosen. Valentinus produced a variety of writings, of which for the most part only fragments quoted by his opponents survive. However, it has recently been argued that Valentinus's lost letter to Agathapous, quoted by Clement of Alexandria, is in fact Letter 366 of Pseudo-Basil.
GnosticismGnosticism (from Ancient Greek: γνωστικός, romanized: gnōstikós, Koine Greek: [ɣnostiˈkos], 'having knowledge') is a collection of religious ideas and systems that coalesced in the late 1st century AD among Jewish and early Christian sects. These various groups emphasized personal spiritual knowledge (gnosis) above the proto-orthodox teachings, traditions, and authority of religious institutions. Gnostic cosmogony generally presents a distinction between a supreme, hidden God and a malevolent lesser divinity (sometimes associated with the God of the Hebrew Bible) who is responsible for creating the material universe.
