Gospel of Luke in the context of Four-document hypothesis

Christianity is an Abrahamic monotheistic religion, which states that Jesus is the Son of God and rose from the dead after his crucifixion, whose coming as the messiah (Christ) was prophesied in the Old Testament and chronicled in the New Testament. It is the world's largest and most widespread religion with over 2.3 billion followers, comprising around 28.8% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 120 countries and territories.

Christianity remains culturally diverse in its Western and Eastern branches, and doctrinally diverse concerning justification and the nature of salvation, ecclesiology, ordination, and Christology. Most Christian denominations, however, generally hold in common the belief that Jesus is God the Son—the Logos incarnated—who ministered, suffered, and died on a cross, but rose from the dead for the salvation of humankind; this message is called the gospel, meaning the "good news". The four canonical gospels of Matthew, Mark, Luke and John describe Jesus' life and teachings as preserved in the early Christian tradition, with the Old Testament as the gospels' respected background.

In 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 that there were seventy apostles during the time of Jesus' ministry.

The commissioning of the Twelve Apostles during the ministry of Jesus is described in the Synoptic Gospels. After his resurrection, Jesus sent eleven of them (as Judas Iscariot by then had died) by the Great Commission to spread his teachings to all nations.

Mary was a first-century Jewish woman of Nazareth, the wife of Joseph and the mother of Jesus. She is an important figure of Christianity, venerated under various titles such as virgin or queen, many of them mentioned in the Litany of Loreto. The Eastern and Oriental Orthodox, Catholic, Evangelical Lutheran, Reformed, Anglican, Methodist and Baptist churches believe that Mary, as mother of Jesus, is the Mother of God. The Church of the East historically regarded her as Christotokos, a term still used in Assyrian Church of the East liturgy. She has the highest position in Islam among all women and is mentioned numerous times in the Quran, including in a chapter named after her. She is also revered in the Baháʼí Faith and the Druze Faith.

The synoptic Gospels name Mary as the mother of Jesus. The gospels of Matthew and Luke describe Mary as a virgin who was chosen by God to conceive Jesus through the Holy Spirit. After giving birth to Jesus in Bethlehem, she and her husband Joseph raised him in the city of Nazareth in Galilee, and she was in Jerusalem at his crucifixion and with the apostles after his ascension. Although her later life is not accounted in the Bible; Catholic, Eastern Orthodox, and some Protestant traditions believe that her body was raised into heaven at the end of her earthly life, which is known in Western Christianity as the Assumption of Mary and in Eastern Christianity as the Dormition of the Mother of God.

The ministry of Jesus, in the canonical gospels, begins with his baptism near the River Jordan by John the Baptist, and ends in Jerusalem in Judea, following the Last Supper with his disciples. The Gospel of Luke states that Jesus was "about 30 years of age" at the start of his ministry. A chronology of Jesus typically sets the date of the start of his ministry at around AD 27–29 and the end in the range AD 30–36.

Jesus' early Galilean ministry begins when after his baptism, he goes back to Galilee from his temptation in the Judaean Desert. In this early period, he preaches around Galilee and recruits his first disciples who begin to travel with him and eventually form the core of the early Church as it is believed that the apostles dispersed from Jerusalem to found the apostolic sees. The major Galilean ministry which begins in Matthew 8 includes the commissioning of the Twelve Apostles, and covers most of the ministry of Jesus in Galilee. The final Galilean ministry begins after the beheading of John the Baptist as Jesus prepares to go to Jerusalem.

The Acts of the Apostles (Koine Greek: Πράξεις Ἀποστόλων, Práxeis Apostólōn and Latin: Actūs Apostolōrum) is the fifth book of the New Testament. It recounts the founding of the Christian Church and the spread of its message across the Roman Empire.

Acts and the Gospel of Luke form a two-volume work known as Luke–Acts by the same author. Tradition identifies the writer as Luke the Evangelist, a doctor who travelled with Paul the Apostle, though the text is anonymous, not naming its author. Critical opinion remains divided about whether Luke the physician wrote it. Many scholars still regard the author of Luke–Acts as a companion of Paul, although they note tensions with the Pauline epistles. Most scholars treat Acts as historiography, though focus is more on the author's aims than on settling questions of strict historicity. Scholars usually date the book to 80–90 AD.

The Gospel of Mark is the second of the four canonical Gospels and one of the three synoptic Gospels. It tells of the ministry of Jesus from his baptism by John the Baptist to his death, the burial of his body, and the discovery of his empty tomb. It portrays Jesus as a teacher, an exorcist, a healer, and a miracle worker. Jesus refers to himself as the Son of Man and is called the Son of God, though he keeps his messianic nature secret; even his disciples fail to understand him. This is in keeping with the Christian interpretation of prophecy, which is believed to foretell the fate of the messiah as a suffering servant.

Traditionally attributed to Mark the Evangelist, the companion of the Apostle Peter, the gospel is anonymous, and scholarship is inconclusive on its authorship. It is dated to around 70 AD and was likely written in Rome for a gentile audience. Mark is classified as an ancient biography and was meant to strengthen the faith of its readers. Most scholars hold that Mark is the earliest gospel and was used by both Matthew and Luke. Mark has therefore often been seen as the most reliable gospel, though this has recently been challenged.

John the Baptist (c. 6 BC – c. AD 30) was a Jewish preacher active in the area of the Jordan River in the early first century AD. He is also known as Saint John the Forerunner in Eastern Orthodoxy and Oriental Orthodoxy, Saint John the Immerser in the Baptist tradition, and as the prophet Yahya ibn Zakariya in Islam. He is sometimes referred to as John the Baptiser.

John is mentioned by the Roman Jewish historian Josephus, and he is revered as a major religious figure in Christianity, Islam, the Baháʼí Faith, the Druze faith, and Mandaeism; in the last of these he is considered to be the final and most vital prophet. He is considered to be a prophet of God by all of the aforementioned faiths, and is honoured as a saint in many Christian denominations. According to the New Testament, John anticipated a messianic figure greater than himself; in the Gospels, he is portrayed as the precursor or forerunner of Jesus. According to the Gospel of Matthew, Jesus himself identifies John as "Elijah who is to come", which is a direct reference to the Book of Malachi (Malachi 4:5), as confirmed by the angel Gabriel, who announced John's birth to his father Zechariah. According to the Gospel of Luke, John and Jesus were relatives.

Most Christian denominations believe the Holy Spirit, or Holy Ghost, to be the third divine Person of the Trinity, a triune god manifested as God the Father, God the Son, and God the Holy Spirit, each being God. Nontrinitarian Christians, who reject the doctrine of the Trinity, differ significantly from mainstream Christianity in their beliefs about the Holy Spirit. In Christian theology, pneumatology is the study of the Holy Spirit. Due to Christianity's historical relationship with Judaism, theologians often identify the Holy Spirit with the concept of the Ruach Hakodesh in Jewish scripture, on the theory that Jesus was expanding upon these Jewish concepts. Similar names, and ideas, include the Ruach Elohim (Spirit of God), Ruach YHWH (Spirit of Yahweh), and the Ruach Hakodesh (Holy Spirit). In the New Testament the Holy Spirit is identified with the Spirit of Christ, the Spirit of Truth, and the Paraclete (helper).

The New Testament details a close relationship between the Holy Spirit and Jesus during his earthly life and ministry. The Gospels of Matthew and Luke and the Nicene Creed state that Jesus was "conceived by the Holy Spirit, born of the Virgin Mary". The Holy Spirit descended on Jesus like a dove during his baptism, and in his Farewell Discourse after the Last Supper, Jesus promised to send the Holy Spirit to his disciples after his departure.

The gospels of Matthew, Mark, and Luke are referred to as the synoptic Gospels because they include many of the same stories, often in a similar sequence and in similar or sometimes identical wording. They stand in contrast to John, whose content is largely distinct. The term synoptic (Latin: synopticus; Greek: συνοπτικός, romanized: synoptikós) comes via Latin from the Greek σύνοψις, synopsis, i.e. "(a) seeing all together, synopsis". The modern sense of the word in English is of "giving an account of the events from the same point of view or under the same general aspect". It is in this sense that it is applied to the synoptic gospels.

This strong parallelism among the three gospels in content, arrangement, and specific language is widely attributed to literary interdependence, though the role of orality and memorization of sources has also been explored by scholars. The question of the precise nature of their literary relationship—the synoptic problem—has been a topic of debate for centuries and has been described as "the most fascinating literary enigma of all time". While no conclusive solution has been found yet, the longstanding majority view favors Marcan priority, in which both Matthew and Luke have made direct use of the Gospel of Mark as a source, and further holds that Matthew and Luke also drew from an additional hypothetical document, called Q, though alternative hypotheses that posit direct use of Matthew by Luke or vice versa without Q are increasing in popularity within scholarship.

The seventy disciples (Greek: ἑβδομήκοντα μαθητές, hebdomikonta mathetes), known in the Eastern Christian traditions as the seventy apostles (Greek: ἑβδομήκοντα απόστολοι, hebdomikonta apostoloi), 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.

The passage from Luke 10 in the Gospel of Luke, the only gospel in which they are mentioned, includes specific instructions for the mission, beginning with (in Douay–Rheims Bible):

The Christian Gospels of Mark and Matthew say that, after the Ascension of Jesus, his Apostles "went out and preached everywhere". This is described in Mark 16 verses 19 and 20, and Matthew 28 verses 19 and 20. According to a tradition mentioned by Eusebius, they dispersed to distinct parts of the world. In the Middle Ages, a liturgical feast of the Dispersion of the Apostles was celebrated to commemorate their missionary work and their founding the apostolic sees. This annual feast was held on 15 July and ranked as a major double.

The Acts of the Apostles, the canonical sequel to the Gospel of Luke, portrays the dispersal as occurring a substantial time after the ascension, with the ministry staying in Jerusalem at first and spreading from there beginning with the conversion of the Ethiopian eunuch.

Judas Iscariot (/ˈdʒuːdəs ɪˈskæriət/; Biblical Greek: Ἰούδας Ἰσκαριώτης, romanized: Ioúdas Iskariṓtēs; c. 3 AD – c. 30 to 33 AD) was, according to Christianity's four canonical gospels, one of the original Twelve Apostles of Jesus Christ. Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane, in exchange for thirty pieces of silver, by kissing him on the cheek and addressing him as "master" to reveal his identity in the darkness to the crowd who had come to arrest him. In modern times, his name is often used synonymously with betrayal or treason.

The Gospel of Mark gives no motive for Judas's betrayal but does present Jesus's predicting it at the Last Supper, an event also described in all the other gospels. The Gospel of Matthew 26:15 states that Judas committed the betrayal in exchange for thirty pieces of silver. The Gospel of Luke 22:3 and the Gospel of John 13:2 and 13:27 suggest that he was possessed by Satan. According to Matthew 27:1–10, after learning that Jesus was to be crucified, Judas attempted to return the money he had been paid for his betrayal to the chief priests and hanged himself. The priests used the money to buy a field to bury strangers in, which was called the "Field of Blood" because it had been bought with blood money. Acts of the Apostles 1:18 quotes Peter as saying that Judas used the money to buy the field himself, and he "[fell] headlong ... burst asunder in the midst, and all his bowels gushed out." His place among the Twelve Apostles was later filled by Matthias.

Anamnesis is also a key concept in the liturgical theology: in worship, Christians recall God's saving deeds. This memorial aspect is not simply a passive process but one by which the Christian can actually enter into the Paschal mystery.

The Annunciation (/əˌnʌnsiˈeɪʃən/; from Latin annuntiatio; also referred to as the Annunciation to the Blessed Virgin Mary, the Annunciation of Our Lady, or the Annunciation of the Lord; Ancient Greek: Ο Ευαγγελισμός της Θεοτόκου) is, according to the Gospel of Luke, the announcement made by the archangel Gabriel to Mary that she would conceive and bear a son through a virgin birth and become the mother of Jesus Christ, the Messiah and Son of God, marking the Incarnation.

According to Luke 1:26 the Annunciation occurred in the sixth month of Elizabeth's pregnancy with John the Baptist. Many Christians observe this event with the Feast of the Annunciation on 25 March, an approximation of the northern vernal equinox nine full months before Christmas, the traditional birthday of Jesus.

The Nativity or birth of Jesus Christ is found in the biblical gospels of Matthew and Luke. The two accounts agree that Jesus was born in Bethlehem, modern day Palestine, in Roman-controlled Judea, that his mother, Mary, was engaged to a man named Joseph, who was descended from King David and was not his biological father, and that his birth was caused by divine intervention. The majority of contemporary scholars do not see the two canonical gospel Nativity stories as historically factual since they present clashing accounts and irreconcilable genealogies. The secular history of the time does not synchronize with the narratives of the birth and early childhood of Jesus in the two gospels. Some view the question of historicity as secondary, given that gospels were primarily written as theological documents rather than chronological timelines.

The Nativity is the basis for the Christian holiday of Christmas and plays a major role in the Christian liturgical year. Many Christians traditionally display small manger scenes depicting the Nativity within or outside of their homes, or attend Nativity plays or Christmas pageants focusing on the Nativity cycle in the Bible. Elaborate Nativity displays featuring life-sized statues are a tradition in many continental European countries during the Christmas season.

A Hodegetria, or Virgin Hodegetria, is an iconographic depiction of the Theotokos (Virgin Mary) holding the Child Jesus at her side while pointing to him as the source of salvation for mankind. The Virgin's head usually inclines towards the child, who raises his hand in a blessing gesture. Metals are often used to draw attention to young Christ, reflecting light and shining in a way to embody divinity. In the Western Church this type of icon is sometimes called Our Lady of the Way.

The most venerated icon of the Hodegetria type, regarded as the original, was displayed in the Monastery of the Panaghia Hodegetria in Constantinople, which was built specially to contain it. The painting became known as the Madonna of Constantinople. Unlike most later copies it showed the Theotokos standing full-length. It was said to have been brought back from the Holy Land by Eudocia, the wife of emperor Theodosius II (408–450), and to have been painted by Saint Luke the evangelist, the attributed author of the Gospel of Luke. The icon was double-sided, with a crucifixion on the other side, and was "perhaps the most prominent cult object in Byzantium".
