Gospel of John in the context of "Born again"

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.

Andrew the Apostle (Koine Greek: Ἀνδρέας, romanized: Andréas [anˈdre.aːs̠]; Latin: Andreas [än̪ˈd̪reː.äːs]; Aramaic: אַנדּרֵאוָס; Classical Syriac: ܐܰܢܕ݁ܪܶܐܘܳܣ, romanized: ʾAnd'raʾwās) was an apostle of Jesus. According to the New Testament, he was a fisherman and one of the Twelve Apostles chosen by Jesus.

The title First-Called (Πρωτόκλητος, Prōtoklētos) used by the Eastern Orthodox Church stems from the Gospel of John, where Andrew, initially a disciple of John the Baptist, follows Jesus and, recognising him as the Messiah, introduces his brother Simon Peter to him.

A Gospel Book, Evangelion, or Book of the Gospels (Greek: Εὐαγγέλιον, Evangélion) is a codex or bound volume containing one or more of the four Gospels of the Christian New Testament – normally all four – centering on the life of Jesus of Nazareth and the roots of the Christian faith. The term is also used for a liturgical book, also called the Evangeliary, from which are read the portions of the Gospels used in the Mass and other services, arranged according to the order of the liturgical calendar.

Liturgical use in churches of a distinct Gospel book remains normal, often compulsory, in Eastern Christianity, and very common in Roman Catholicism and some parts of Anglicanism and Lutheranism.

In Christianity, the Logos (Greek: o Λόγος, lit. 'the word, discourse, or reason') is a name or title of Jesus Christ, seen as the pre-existent second person of the Trinity. In the Douay–Rheims, King James, New International, and other versions of the Bible, the first verse of the Gospel of John reads:

In these translations, Word is used for Λόγος, although the term is often used transliterated but untranslated in theological discourse.

According to the New Testament, a woven crown of thorns (Ancient Greek: στέφανος ἐξ ἀκανθῶν, romanized: stephanos ex akanthōn or ἀκάνθινος στέφανος, akanthinos stephanos) was placed on the head of Jesus during the events leading up to his crucifixion. It was one of the instruments of the Passion, employed by Jesus' captors both to cause him pain and to mock his claim of authority. It is mentioned in the gospels of Matthew (Matthew 27:29), Mark (Mark 15:17) and John (John 19:2, 19:5), and is often alluded to by the early Church Fathers, such as Clement of Alexandria, Origen and others, along with being referenced in the apocryphal Gospel of Peter.

Since around 400 AD, a relic has been venerated as the crown of thorns. Louis IX acquired it in 1239 from the emperor Baldwin Il, who was financially in debt due to heavy military expenses. Louis IX built the Sainte-Chapelle as a monumental reliquary to house the relic. Transferred to the French National Library during the Revolution of the 18th century, the crown of thorns has been displayed at Notre-Dame de Paris since 1804. The crown is made of reeds, formed into a circle and attached with reed fasteners. On 15 April 2019, it was rescued from a fire and moved to the Louvre Museum. In December of 2024, a ceremony marking the relic's return to Notre Dame Cathedral was led by a procession attended by members of the Equestrian Order of the Holy Sepulchre. Veneration of the crown of thorns takes place every first Friday of the month from 3 pm to 5 pm.

Lamb of God (Greek: Ἀμνὸς τοῦ Θεοῦ, romanized: Amnòs toû Theoû; Latin: Agnus Dei, Ecclesiastical Latin: [ˈaɲ.ɲus ˈde.i]) is a title for Jesus that appears in the Gospel of John. It appears at John 1:29, where John the Baptist sees Jesus and exclaims, "Behold the Lamb of God who takes away the sin of the world." It appears again in John 1:36.

Christian doctrine holds that a divine Jesus chose to suffer crucifixion at Calvary to save the world from its sins. He was given up by divine Father, as an "agent and servant of God" in carrying away the sins of the world. In Christian theology the Lamb of God is viewed as both foundational and integral to the message of Christianity.

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 Last Supper (Italian: Il Cenacolo [il tʃeˈnaːkolo] or L'Ultima Cena [ˈlultima ˈtʃeːna]) is a mural painting by the Italian High Renaissance artist Leonardo da Vinci, dated to c. 1495–1498, housed in the refectory of the Convent of Santa Maria delle Grazie in Milan, Italy. The painting represents the scene of the Last Supper of Jesus with the Twelve Apostles, as it is told in the Gospel of John – specifically the moment after Jesus announces that one of his apostles will betray him. Its handling of space, mastery of perspective, treatment of motion and complex display of human emotion has made it one of the Western world's most recognizable paintings and among Leonardo's most celebrated works. Some commentators consider it pivotal in inaugurating the transition into what is now termed the High Renaissance.

The work was commissioned as part of a plan of renovations to the church and its convent buildings by Leonardo's patron Ludovico Sforza, Duke of Milan. In order to permit his inconsistent painting schedule and frequent revisions, it is painted with materials that allowed for regular alterations: tempera on gesso, pitch, and mastic. Due to the methods used, a variety of environmental factors, and intentional damage, little of the original painting remains today despite numerous restoration attempts, the last being completed in 1999. The Last Supper is Leonardo's largest work, aside from the Sala delle Asse.

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.
