Context: The Old Testament is the first section of the Christian Bible, based primarily upon the Hebrew Bible (or Tanakh), a collection of religious writings by ancient Israelites believed by most Christians and religious Jews to be the sacred Word of God. It is the counterpart to the New Testament, the second portion of the Christian Bible. The Old Testament canon varies between Christian Churches. Protestants have a version with 39 books. Catholics have a version with 46 books, and Eastern Orthodox, and Oriental Orthodox Churches choose the Old Testament version with 49 books., The Apostolic Age of the history of Christianity is traditionally regarded as the period of the Twelve Apostles, dating from the Great Commission of the Apostles by the risen Jesus in Jerusalem around 33 AD until the death of the last Apostle, believed to be John the Apostle in Anatolia c. 100. Traditionally, the Apostles are believed to have dispersed from Jerusalem, founding the Apostolic Sees. It holds special significance in Christian tradition as the age of the direct apostles of Jesus Christ. One major primary source for the ""Apostolic Age"" is the Acts of the Apostles, but its historical accuracy is questioned by some and its coverage is partial, focusing especially from onwards on the ministry of Paul (not one of the twelve apostles) and his companions, and ending around 62 AD with Paul preaching in Rome under house arrest., The Council of Jerusalem or Apostolic Council was held in Jerusalem around 50 AD. It is unique among the ancient pre-ecumenical councils in that it is considered by Catholics and Orthodox to be a prototype and forerunner of the later ecumenical councils and a key part of Christian ethics. The council decided that Gentile converts to Christianity were not obligated to keep most of the Law of Moses, including the rules concerning circumcision of males. The Council did, however, retain the prohibitions on eating blood, meat containing blood, and meat of animals not properly slain, and on fornication and idolatry, sometimes referred to as the Apostolic Decree or Jerusalem Quadrilateral., The Ante-Nicene Fathers, subtitled ""The Writings of the Fathers Down to A.D. 325"", is a collection of books in 10 volumes (one volume is indexes) containing English translations of the majority of Early Christian writings. The period covers the beginning of Christianity until before the promulgation of the Nicene Creed at the First Council of Nicaea. The translations are very faithful, and provide valuable insights into the spirituality and theology of the early Church fathers., An ecumenical council (or oecumenical council; also general council) is a conference of ecclesiastical dignitaries and theological experts convened to discuss and settle matters of Church doctrine and practice in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church., John the Apostle ( Koine Greek: ; Latin: "Ioannes") was one of the Twelve Apostles of Jesus according to the New Testament, which refers to him as . He was the son of Zebedee and Salome. His brother was James, who was another of the Twelve Apostles. Christian tradition holds that he outlived the remaining apostles and that he was the only one to die of natural causes: Judas Iscariot died by suicide, while the other ten all are considered to have died a martyr's death. This is because the Church Fathers considered him the same person as John the Evangelist, John of Patmos, John the Elder and the Beloved Disciple, although modern theologians and scholars have not formed a consensus on the relative identities of these men. The traditions of most Christian denominations have held that John the Apostle is the author of several books of the New Testament., Nicaea or Nicea was an ancient city in northwestern Anatolia, and is primarily known as the site of the First and Second Councils of Nicaea (the first and seventh Ecumenical councils in the early history of the Christian Church), the Nicene Creed (which comes from the First Council), and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261., In justice and law, house arrest (also called home confinement, home detention, or electronic monitoring) is a measure by which a person is confined by the authorities to a certain residence. Travel is usually restricted, if allowed at all. House arrest is an alternative to prison time or juvenile-detention time., The First Council of Nicaea was a council of Christian bishops convened in the Bithynian city of Nicaea (now Iznik, Bursa province, Turkey) by the Roman Emperor Constantine I in AD 325. This first ecumenical council was the first effort to attain consensus in the Church through an assembly representing all of Christendom, although previous councils, including the first Church council, the Council of Jerusalem, had met before to settle matters of dispute. It was presided over by Hosius, bishop of Corduba who was in communion with the See of Rome., The history of early Christianity covers the period from the its origins to the First Council of Nicaea in 325., The Ante-Nicene Period (literally meaning "before Nicaea") of the history of early Christianity was the period following the Apostolic Age of the 1st century down to the First Council of Nicaea in 325. This period of Christian history had a significant impact on the unity of doctrine across all Christendom and the spreading of Christianity to a greater area of the world. Those seen as prominent figures of this era, referred to as the Ante-Nicene Fathers or Proto-orthodox Christians, generally agreed on most doctrine while the teachings of those early Christian writers which the general majority considered to be heretical, were rejected. , Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states. , In Christianity, the Great Commission is the instruction of the resurrected Jesus Christ to his disciples to spread his teachings to all the nations of the world. The most famous version of the Great Commission is in , where on a mountain in Galilee Jesus calls on his followers to baptize all nations in the name of the Father, the Son, and the Holy Spirit., A Christian (or ) is a person who follows or adheres to Christianity, an Abrahamic, monotheistic religion based on the life and teachings of Jesus Christ. "Christian" derives from the Koine Greek word "Christós" (), a translation of the Biblical Hebrew term "mashiach"., In the study of history as an academic discipline, a primary source (also called original source or evidence) is an artifact, a document, diary, manuscript, autobiography, a recording, or other source of information that was created at the time under study. It serves as an original source of information about the topic. Similar definitions can be used in library science, and other areas of scholarship, although different fields have somewhat different definitions. In journalism, a primary source can be a person with direct knowledge of a situation, or a document written by such a person., The history of Christianity concerns the Christian religion, Christendom, and the Church with its various denominations, from the 1st century to the present., The Acts of the Apostles ("Práxeis tôn Apostóln"), often referred to simply as Acts, is the fifth book of the New Testament; it tells of the founding of the Christian church and the spread of its message to the Roman Empire., Christianity is a monotheistic religion based on the life and teachings of Jesus Christ, who serves as the focal point for the religion. It is the world's largest religion, with over 2.4 billion followers, or 33% of the global population, known as Christians. Christians believe that Jesus is the Son of God and the savior of humanity whose coming as the Messiah (the Christ) was prophesied in the Old Testament., In Abrahamic religions, the Messiah or Messias is a saviour or liberator of a group of people, more specifically, the Jewish people., Bithynia (Greek "Bithynia") was an ancient region, kingdom and Roman province in the northwest of Asia Minor, adjoining the Propontis, the Thracian Bosporus and the Euxine Sea. It bordered on Mysia to the south-west, Paphlagonia to the north-east along the Pontic coast, and Phrygia to the south-east towards the interior of Asia Minor. Bithynia was an independent kingdom from 4th century BC. Its capital Nicomedia was rebuilt on the site of ancient Astacus in 264 BC by Nicomedes I of Bithynia. Bithynia fell to the Roman Republic in 74 BC, and became united with the Pontus region as the province of Bithynia et Pontus, in the 7th century incorporated into the Byzantine Opsikion theme.
It became a border region to the Seljuk Empire in the 13th century, and was eventually conquered by the Ottoman Turks in the 1330s., Jesus (; c. 4 BC  c. AD 30/33), also referred to as Jesus of Nazareth or Jesus Christ, was a Jewish preacher and religious leader who became the central figure of Christianity. Christians believe him to be the Son of God and the awaited Messiah (Christ) prophesied in the Old Testament.
Virtually all modern scholars of antiquity agree that Jesus existed historically, although the quest for the historical Jesus has produced little agreement on the historical reliability of the Gospels and on how closely the biblical Jesus reflects the historical Jesus. Jesus was a Galilean Jew who was baptized by John the Baptist and subsequently began his own ministry, preaching his message orally and often being referred to as "rabbi". He was arrested and tried by the Jewish authorities, and was crucified by the order of Pontius Pilate, the Roman prefect. Jesus debated fellow Jews on how to best follow God, performed healings, taught in parables and gathered followers. After his death, his followers believed he rose from the dead, and the community they formed eventually became the Christian Church., Religion is a cultural system of behaviors and practices, world views, sacred texts, holy places, ethics, and societal organisation that relate humanity to what an anthropologist has called "an order of existence". Different religions may or may not contain various elements, ranging from the "divine", "sacred things", "faith", a "supernatural being or supernatural beings" or "some sort of ultimacy and transcendence that will provide norms and power for the rest of life.", In Catholicism, an apostolic see is any episcopal see whose foundation is attributed to one or more of the apostles of Jesus., Early Christianity is the period of Christianity preceding the First Council of Nicaea in 325 . It is typically divided into the Apostolic Age and the Ante - Nicene Period ( from the Apostolic Age until Nicea ) . The first Christians , as described in the first chapters of the Acts of the Apostles , were all Jewish , either by birth , or conversion for which the biblical term proselyte is used , and referred to by historians as the Jewish Christians . The early Gospel message was spread orally ; probably in Aramaic , but almost immediately also in Greek . The New Testament 's Book of Acts and Epistle to the Galatians record that the first Christian community was centered in Jerusalem and its leaders included Peter , James , and John . Paul of Tarsus , after his conversion to Christianity , claimed the title of `` Apostle to the Gentiles '' . Paul 's influence on Christian thinking is said to be more significant than that of any other New Testament author . By the end of the 1st century , Christianity began to be recognized internally and externally as a separate religion from Judaism which itself was refined and developed further in the centuries after the destruction of the Second Jerusalem Temple . Numerous quotations in the New Testament and other Christian writings of the 1st centuries , indicate that early Christians generally used and revered the Jewish Bible ( the Tanakh ) as Scripture , mostly in the Greek ( Septuagint ) or Aramaic ( Targum ) translations . As the New Testament canon developed , the Letters of Paul , the canonical gospels and various other works were also recognized as scripture to be read in church . Paul 's letters , especially Romans , established a theology based on Christ rather than on the Mosaic Law , but most Christian denominations today still consider the `` moral prescriptions '' of the Mosaic Law , such as the Ten Commandments , Great Commandment , and Golden Rule , to be relevant . Early Christians demonstrated a wide range of beliefs and practices , many of which were later denounced as heretical ., Subject: early christianity, Relation: part_of, Options: (A) 1330s (B) 1st century (C) 4th century bc (D) acts of the apostles (E) asia (F) book (G) c (H) catholicism (I) christian church (J) christianity (K) church (L) city (M) community (N) eating (O) empire (P) english (Q) ethics (R) fourth crusade (S) history (T) history of christianity (U) house (V) jerusalem (W) jesus christ (X) jewish people (Y) journalism (Z) law ([) messiah (\) name (]) new testament (^) old testament (_) part (`) person (a) religion (b) river (c) roman empire (d) science (e) sea (f) system (g) tanakh (h) the city (i) theology
