John the Baptist in the context of "Life of Jesus"

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.

In Christian belief, a saint, also known as a hallow, is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term saint depends on the context and denomination. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. The saints are honored in the liturgical calendars of Evangelical Lutheranism and Anglicanism. In other nonconformist denominations, such as the Plymouth Brethren, and following from Pauline usage, saint refers broadly to any holy Christian without special recognition or selection.

While the English word saint (deriving from the Latin sanctus) originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people", referring to the Hindu rishi, Sikh bhagat or guru, the Shintoist kami, the Taoist immortal or zhenren, the Jewish tzadik, the Islamic walī/fakir, and the Buddhist arhat or bodhisattva also as saints. Depending on the religion, saints are recognized either by official declaration, as in Roman Catholicism, Oriental Orthodoxy or Eastern Orthodoxy, or by popular acclamation (see folk saint).

Jesus (c. 6 to 4 BC – AD 30 or 33), also referred to as Jesus Christ, Jesus of Nazareth, and many other names and titles, was a 1st-century Jewish preacher and religious leader in the Roman province of Judaea. He is the central figure of Christianity, the world's largest religion. Most Christians consider Jesus to be the incarnation of God the Son and awaited messiah, or Christ, a descendant from the Davidic line that is prophesied in the Old Testament. Virtually all modern scholars of antiquity agree that Jesus existed historically. Accounts of Jesus's life are contained in the Gospels, especially the four canonical Gospels in the New Testament. Since the Enlightenment, academic research has yielded various views on the historical reliability of the Gospels and how closely they reflect the historical Jesus.

According to Christian tradition, as preserved in the Gospels and the Acts of the Apostles, Jesus was circumcised at eight days old, was baptized by John the Baptist as a young adult, and after 40 days and nights of fasting in the wilderness, began his own ministry. He was an itinerant teacher who interpreted the law of God with divine authority and was often referred to as "rabbi". Jesus often debated with his fellow Jews on how to best follow God, engaged in healings, taught in parables, and gathered followers, among whom 12 were appointed as his apostles. He was arrested in Jerusalem and tried by the Jewish authorities, handed over to the Roman government, and crucified on the order of Pontius Pilate, the Roman prefect of Judaea. After his death, his followers became convinced that he rose from the dead, and following his ascension, the community they formed eventually became the early Christian Church that expanded as a worldwide movement.

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 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.

Baptism (from Koine Greek: βάπτισμα, romanized: váptisma, lit. 'immersion, dipping in water') is a Christian rite of initiation almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or immersing in water (partially or completely), traditionally three times for each person of the Trinity. It is also called christening, although this is typically reserved for the baptism of infants. Baptism is regarded as a sacrament in most churches and an ordinance in others, with the synoptic gospels recounting that John the Baptist baptized Jesus.

Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. In certain Christian denominations, such as the Catholic Churches, Eastern Orthodox Churches, Oriental Orthodox Churches, Assyrian Church of the East, and Lutheran Churches, baptism is the door to church membership, with candidates taking baptismal vows. It has also given its name to the Baptist churches and denominations.

San Juan (/ˌsæn ˈhwɑːn/ san WHAHN, Spanish: [saŋ ˈxwan]; Spanish for "Saint John") is the capital city and most populous municipality in the Commonwealth of Puerto Rico, an unincorporated territory of the United States. As of the 2020 census, it is the 57th-most populous city under the jurisdiction of the United States, with a population of 342,259. San Juan was founded by Spanish colonists in 1521, who called it Ciudad de Puerto Rico (Spanish for "Rich Port City").

Puerto Rico's capital is the second oldest European-established capital city in the Americas, after Santo Domingo, in the Dominican Republic, founded in 1496, and is the oldest European-established city under United States sovereignty. Several historical buildings are located in the historic district of Old San Juan; among the most notable are the city's former defensive walls, Fort San Felipe del Morro and Fort San Cristóbal, and La Fortaleza, the oldest executive mansion in continuous use in the Americas. These historic sites were declared a UNESCO World Heritage Site in 1983.

The Order of Knights of the Hospital of Saint John of Jerusalem, commonly known as the Knights Hospitaller (/ˈhɒspɪtələr/), is a Catholic military order. It was founded in the crusader Kingdom of Jerusalem in the 12th century and had its headquarters there, in Jerusalem and Acre, until 1291, thereafter being based in Kolossi Castle in Cyprus (1302–1310), the island of Rhodes (1310–1522), Malta (1530–1798), and Saint Petersburg (1799–1801).

The Hospitallers arose in the early 12th century at the height of the Cluniac movement, a reformist movement within the Benedictine monastic order that sought to strengthen religious devotion and charity for the poor. Earlier in the 11th century, merchants from Amalfi founded a hospital in Jerusalem dedicated to John the Baptist where Benedictine monks cared for sick, poor, or injured Christian pilgrims to the Holy Land. Blessed Gerard, a lay brother of the Benedictine order, became its head when it was established. After the Christian conquest of Jerusalem in 1099 during the First Crusade, the Hospitallers rose in prominence and were recognized as a distinct order by Pope Paschal II in 1113.
