Twelve Apostles in the context of "Saint Peter"

A bishop is an ordained member of the clergy who is entrusted with a position of authority and oversight in a religious institution. In Christianity, bishops are normally responsible for the governance and administration of dioceses. The role or office of the bishop is called episcopacy or the episcopate. Organisationally, several Christian denominations utilise ecclesiastical structures that call for the position of bishops, while other denominations have dispensed with this office, seeing it as a symbol of power. Bishops have also exercised political authority within their dioceses.

Traditionally, bishops claim apostolic succession and the historic episcopacy, a direct historical lineage dating back to the original Twelve Apostles or Saint Paul. The bishops are by doctrine understood as those who possess the full priesthood given by Jesus Christ, and therefore may ordain other clergy, including other bishops. A person ordained as a deacon, priest (i.e. presbyter), and then bishop is understood to hold the fullness of the ministerial priesthood, given responsibility by Christ to govern, teach and sanctify the Body of Christ (the Christian Church). Priests, deacons and lay ministers co-operate and assist their bishops in pastoral ministry.

Apostolic succession is the method whereby the ministry of the Christian Church is considered by some Christian denominations to be derived from the apostles by a continuous succession, which has usually been associated with a claim that the succession is through a series of bishops. Those of the Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East traditions maintain that a bishop's orders are neither regular nor valid without consecration through apostolic succession. These traditions do not always consider the episcopal consecrations of all of the other traditions as valid.

This series was seen originally as that of the bishops of a particular see founded by one or more of the apostles. According to historian Justo L. González, apostolic succession is generally understood today as meaning a series of bishops, regardless of see, each consecrated by other bishops, themselves consecrated similarly in a succession going back to the apostles. According to the Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church, "apostolic succession" means more than a mere transmission of powers. It is succession in a church which witnesses to the apostolic faith, in communion with the other churches, witnesses of the same apostolic faith. The "see (cathedra) plays an important role in inserting the bishop into the heart of ecclesial apostolicity", but once ordained, the bishop becomes in his church the guarantor of apostolicity and becomes a successor of the apostles.

Christianity in the 1st century covers the formative history of Christianity from the start of the ministry of Jesus (c. 27–29 AD) to the death of the last of the Twelve Apostles (c. 100) and is thus also known as the Apostolic Age. Early Christianity developed out of the eschatological ministry of Jesus. Subsequent to Jesus' death, his earliest followers formed an apocalyptic messianic Jewish sect during the late Second Temple period of the 1st century. Initially believing that Jesus' resurrection was the start of the end time, their beliefs soon changed in the expected Second Coming of Jesus and the start of God's Kingdom at a later point in time.

Paul the Apostle, a Pharisee Jew, who had persecuted the early Christians of the Roman Province of Judea, converted c. 33–36 and began to proselytize among the Gentiles. According to Paul, Gentile converts could be allowed exemption from Jewish commandments, arguing that all are justified by their faith in Jesus. This was part of a gradual split between early Christianity and Judaism, as Christianity became a distinct religion including predominantly Gentile adherence.

Paul, also named Saul of Tarsus, commonly known as Paul the Apostle or Saint Paul, was a Christian apostle (c. 5 – c. 64/65 AD) who spread the teachings of Jesus in the first-century AD. For his contributions towards the New Testament, he is generally regarded as one of the most important figures of the Apostolic Age, and he also founded several Christian communities in Asia Minor and Europe from the mid-40s to the mid-50s AD.

The main sources of information on Paul's life and works are Paul's letters and the Acts of the Apostles in the New Testament. Approximately half of its content documents his travels, preaching, and miracles. Paul was not one of the Twelve Apostles, and he did not know Jesus during his lifetime. Nonetheless, Paul was a contemporary of Jesus and personally knew eyewitnesses of Jesus such as his closest disciples (Peter and John) and brother James since the mid 30s AD, within a few years of the crucifixion (ca. 30–33 AD). He had knowledge of the life of Jesus and his teachings. According to the Acts, Paul lived as a Pharisee and participated in the persecution of early disciples of Jesus before his conversion. On his way to arrest Christians in Damascus, Paul saw a bright light, heard Christ speak, was blinded, and later healed by Ananias. After these events, Paul was baptized, beginning immediately to proclaim that Jesus of Nazareth was the Jewish messiah and the Son of God. He made three missionary journeys to spread the Christian message to non-Jewish communities.

The primacy of Peter, also known as Petrine primacy (from the Latin: Petrus, lit. 'Peter'), is the position of preeminence that is attributed to Peter among the Twelve Apostles.

Julius Schiller (c. 1580 – 1627) was a lawyer from Augsburg who, like his fellow citizen and colleague Johann Bayer, published a star atlas in celestial cartography.

In the year of his death, Schiller, with Bayer's assistance, published the star atlas Coelum Stellatum Christianum which replaced the pagan names of constellations with biblical and early Christian figures. Specifically, Schiller replaced the zodiacal constellations with the twelve apostles, the northern constellations by figures from the New Testament, and the southern constellations by figures from the Old Testament.

The Coelum Stellatum Christianum is a star atlas published in 1627 by Julius Schiller (c. 1580–1627), with the collaboration of Johann Bayer (1572–1625). In the treatise, which was published by Andreas Aperger at Augsburg during the same year as Schiller's death, pagan constellations were replaced with biblical figures and Christian motifs. Schiller replaced the zodiac constellations with the Twelve Apostles, the northern constellations with New Testament figures, and the southern constellations with Old Testament figures.

The planets, the Sun, and the Moon were also replaced by biblical figures:

The commissioning of the Twelve Apostles is an episode in the ministry of Jesus that appears in all three Synoptic Gospels: Matthew 10:1–4, Mark 3:13–19 and Luke 6:12–16. It relates the initial selection of the Twelve Apostles among the disciples of Jesus.

An apostolic see is an episcopal see whose foundation is attributed to one or more of the apostles of Jesus or to one of their close associates. In Catholicism, the phrase "The Apostolic See" when capitalized refers specifically to the See of Rome.

Tertullian (c. 155 − c. 240) gives examples of apostolic sees: he describes as churches "in which the very thrones of the apostles are still pre-eminent in their places, in which their own authentic writings are read, uttering the voice and representing the face of each of them severally" the following churches: Corinth, Philippi, Ephesus, and Rome.

An apostle (/əˈpɒsəl/), in its literal sense, is an emissary. The word is derived from Ancient Greek ἀπόστολος (apóstolos), literally "one who is sent off", itself derived from the verb ἀποστέλλειν (apostéllein), "to send off". The purpose of such sending off is usually to convey a message, and thus "messenger" is a common alternative translation; other common translations include "ambassador" and "envoy". The term in Ancient Greek also has other related meanings.

In Christianity, the term was used in the New Testament for Jesus' Twelve Apostles (including Peter, James, and John), as well as a wider group of early Christian figures, including Paul, Barnabas, and Junia. The term is also used to designate an important missionary of Christianity to a region or a group, e.g. Patrick, the apostle of Ireland, or Boniface, the "apostle of the Germans". Some other religions use the term for comparable figures in their history. The word in this sense may be used metaphorically in various contexts, but is mostly found used specifically for early associates of the founder of a religion, who were important in spreading their teachings. The term is also used to refer to someone who is a strong supporter of something.

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.

A halo (from Ancient Greek ἅλως, hálōs, 'threshing floor, disk'), also called a nimbus, aureole, glory or gloriole (Latin: gloriola, lit. 'little glory'), is a crown of light rays, circle or disk of light that surrounds a person in works of art. The halo occurs in the iconography of many religions to indicate holy or sacred figures, and has at various periods also been used in images of rulers and heroes. In the religious art of Ancient Greece, Ancient Rome, Christianity, Hinduism, and Buddhism (among other religions), sacred persons may be depicted with a halo in the form of a circular glow, or flames in Asian art, around the head or around the whole body—this last form is often called a mandorla.

Halos may be shown as almost any colour or combination of colours, but are most often depicted as golden, yellow or white (when representing light) or as red (when representing flames). The earliest artistic depictions of halos were probably in Ancient Egyptian art.

The history of the Catholic Church is the formation, events, and historical development of the Catholic Church through time.

According to the tradition of the Catholic Church, it started from the day of Pentecost at the upper room of Jerusalem; the Catholic tradition considers that the Church is a continuation of the early Christian community established by the Disciples of Jesus. The Church considers its bishops to be the successors to Jesus's apostles and the Church's leader, the Bishop of Rome (also known as the Pope), to be the sole successor to St Peter who ministered in Rome in the first century AD after his appointment by Jesus as head of the Church. By the end of the 2nd century, bishops began congregating in regional synods to resolve doctrinal and administrative issues. Historian Eamon Duffy claims that by the 3rd century, the church at Rome might have functioned as a court of appeal on doctrinal issues.
