Pentecost in the context of "Greek Orthodox Patriarchate of Jerusalem"

In the Catholic Church, a bishop is an ordained minister who holds the fullness of the sacrament of holy orders and is responsible for teaching doctrine, governing Catholics in his jurisdiction, sanctifying the world and representing the church. Catholics trace the origins of the office of bishop to the apostles, who it is believed were endowed with a special charism and office by the Holy Spirit at Pentecost. Catholics believe this special charism and office has been transmitted through an unbroken succession of bishops by the laying on of hands in the sacrament of holy orders.

Diocesan bishops—known as eparchial bishops in the Eastern Catholic Churches—are assigned to govern local regions within the Catholic Church known as dioceses in the Latin Church and eparchies in the Eastern Churches. Bishops are collectively known as the College of Bishops and can hold such additional titles as archbishop, cardinal, patriarch, or pope. As of 2020, there were approximately 5,600 living bishops total in the Latin and Eastern churches of the Catholic Church.

The Christianization of Iberia (Georgian: ქართლის გაქრისტიანება, romanized: kartlis gakrist'ianeba) refers to the spread of Christianity in the early 4th century as a result of the preaching of Saint Nino in the ancient Georgian kingdom of Kartli, known as Iberia in classical antiquity. The then-pagan king of Iberia Mirian III declared Christianity to be the kingdom's state religion. According to Roman historian Sozomen, this led the king's "large and warlike barbarian nation to confess Christ and renounce the religion of their fathers", as the polytheistic Georgians had long-established anthropomorphic idols, known as the "Gods of Kartli". The king would become the main sponsor, architect, initiator and an organizing power of all building processes.

Per Socrates of Constantinople, the "Iberians first embraced the Christian faith" alongside the Abyssinians, present day Ethiopians but the exact date of the event is still debated. The kings of Georgia and Armenia were among the first monarchs anywhere in the world to convert to the Christian faith. Prior to the escalation of the Armeno-Georgian ecclesiastical rivalry and the Christological controversies, their Caucasian Christianity was extraordinarily inclusive, pluralistic and flexible that only saw the rigid ecclesiological hierarchies established much later, particularly as "national" churches crystallised from the 6th century. Despite the tremendous diversity of the region, the Christianization process was a pan-regional and a cross-cultural phenomenon in the Caucasus, Eurasia's most energetic and cosmopolitan zones throughout the late antiquity, hard enough to place Georgians and Armenians unequivocally within any one major civilization.

Christian tradition is a collection of traditions consisting of practices or beliefs associated with Christianity. Many churches have traditional practices, such as particular patterns of worship or rites, that developed over time. Deviations from such patterns are sometimes considered unacceptable by followers, or are regarded as heretical. There are certain Christian traditions that are practiced throughout the liturgical year, such as praying a daily devotional during Advent, erecting a nativity scene during Christmastide, chalking the door on Epiphany Day, fasting during Lent, waving palms on Palm Sunday, eating easter eggs during Eastertide, and decorating the church in red on Pentecost.

Tradition also includes historic teaching of the recognized church authorities, such as Church Councils and ecclesiastical officials (e.g., the Pope, Patriarch of Constantinople, Archbishop of Canterbury, etc.), and includes the teaching of significant individuals like the Church Fathers, the Protestant Reformers, and the founders of denominations. Many creeds, confessions of faith, and catechisms generated by these bodies are also part of the traditions of various bodies.

A sermon is a religious discourse or oration by a preacher, usually a member of clergy. Sermons address a scriptural, theological, or moral topic, usually expounding on a type of belief, law, or behavior within both past and present contexts. Elements of the sermon often include exposition, exhortation, and practical application. The act of delivering a sermon is called preaching. In secular usage, the word sermon may refer, often disparagingly, to a lecture on morals.

In Christian practice, a sermon is usually preached to a congregation in a place of worship, either from an elevated architectural feature, known as a pulpit or an ambo, or from behind a lectern. The word sermon comes from a Middle English word which was derived from Old French, which in turn originates from the Latin word sermō meaning 'discourse.' A sermonette is a short sermon (usually associated with television broadcasting, as stations would present a sermonette before signing off for the night). The Christian Bible contains many speeches without interlocution, which some take to be sermons: Jesus' Sermon on the Mount in Matthew 5–7 (though the gospel writers do not specifically call it a sermon; the popular descriptor for Jesus' speech there came much later); and Peter after Pentecost in Acts 2:14–40 (though this speech was delivered to non-Christians and as such is not quite parallel to the popular definition of a sermon).

A novena (from Latin: novem, "nine") is an ancient tradition of devotional praying in Christianity, consisting of private or public prayers repeated for nine successive days or weeks. The nine days between the Feast of the Ascension and Pentecost, when the disciples gathered in the Upper Room and devoted themselves to prayer, is often considered to be the first novena.

In some Christian communities, such as in Africa, Latin America and the Philippines, novena traditions are popular and include devotional rituals such as liturgies, congregational prayers, the decoration of statues, hymns and music, processions, as well as communal feasting.

Pentecostalism or classical Pentecostalism is a movement within the evangelical wing of Protestant Christianity that emphasizes direct personal experience of God through baptism with the Holy Spirit. The term Pentecostal is derived from Pentecost, an event that commemorates the descent of the Holy Spirit upon the Apostles and other followers of Jesus Christ while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles (Acts 2:1–31).

Like other forms of evangelical Protestantism, Pentecostalism adheres to the inerrancy of the Bible and the necessity of being born again: an individual repenting of their sin and "accepting Jesus Christ as their personal Lord and Savior". It is distinguished by belief in both the "baptism in the Holy Spirit" and baptism by water, that enables a Christian to "live a Spirit-filled and empowered life". This empowerment includes the use of spiritual gifts: such as speaking in tongues and divine healing. Because of their commitment to biblical authority, spiritual gifts, and the miraculous, Pentecostals see their movement as reflecting the same kind of spiritual power and teachings that were found in the Apostolic Age of the Early Church. For this reason, some Pentecostals also use the term "Apostolic" or "Full Gospel" to describe their movement.

The Florence Baptistery, also known as the Baptistery of Saint John (Italian: Battistero di San Giovanni), is a religious building in Florence, Italy. Dedicated to the patron saint of the city, John the Baptist, it has been a focus of religious, civic, and artistic life since its completion. The octagonal baptistery stands in both the Piazza del Duomo and the Piazza San Giovanni, between Florence Cathedral and the Archbishop's Palace.

Florentine infants were originally baptized in large groups on Holy Saturday and Pentecost in a five-basin baptismal font located at the center of the building. Over the course of the 13th century, individual baptisms soon after birth became common, so less apparatus was necessary. Around 1370 a small font was commissioned, which is still in use today. The original font, disused, was dismantled in 1577 by Francesco I de' Medici to make room for grand-ducal celebrations, an act deplored by Florentines at the time.
