PentecostPentecost (also called Whit Sunday, Whitsunday or Whitsun) is a Christian holiday which takes place on the 50th day (the seventh Sunday) after Easter Sunday. It commemorates the descent of the Holy Spirit upon the Virgin Mary and the Apostles 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). Pentecost is one of the Great feasts in the Eastern Orthodox Church, a Solemnity in the Roman Rite of the Catholic Church, a Festival in the Lutheran Churches, and a Principal Feast in the Anglican Communion.
IdolatryIdolatry is the worship of a or "idol" as though it were God. In Abrahamic religions (namely Judaism, Samaritanism, Christianity, the Baháʼí Faith, and Islam) idolatry connotes the worship of something or someone other than the Abrahamic God as if it were God. In these monotheistic religions, idolatry has been considered as the "worship of false gods" and is forbidden by texts such as the Ten Commandments. Other monotheistic religions may apply similar rules.
God the FatherGod the Father is a title given to God in Christianity. In mainstream trinitarian Christianity, God the Father is regarded as the first person of the Trinity, followed by the second person, God the Son Jesus Christ, and the third person, God the Holy Spirit. Since the second century, Christian creeds included affirmation of belief in "God the Father (Almighty)", primarily in his capacity as "Father and creator of the universe".
EschatologyEschatology (ˌɛskəˈtɒlədʒi; ) concerns expectations of the end of the present age, human history, or the world itself. The end of the world or end times is predicted by several world religions (both Abrahamic and non-Abrahamic), which teach that negative world events will reach a climax. Belief that the end of the world is imminent is known as apocalypticism, and over time has been held both by members of mainstream religions and by doomsday cults.
John the BaptistJohn the Baptist (1st century BC – AD 30) was a Judaean preacher active in the area of the Jordan River in the early 1st century AD. He is also known as John the Forerunner in Eastern Orthodoxy, John the Immerser in some Baptist Christian traditions, and Prophet Yahya in Islam. He is sometimes alternatively 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, the latter in which he is considered to be the final and most vital prophet.
SatanSatan, also known as the Devil, and sometimes also called Lucifer in Christianity, is an entity in Abrahamic religions that seduces humans into sin or falsehood. In Judaism, Satan is seen as an agent subservient to God, typically regarded as a metaphor for the yetzer hara, or "evil inclination". In Christianity and Islam, he is usually seen as a fallen angel or jinn who has rebelled against God, who nevertheless allows him temporary power over the fallen world and a host of demons.
IsraelitesThe Israelites (ˈɪzrəlaɪts,_-riə-; , Bənēy Yīsrāʾēl, ) were a group of Semitic-speaking tribes in the ancient Near East who, during the Iron Age, inhabited a part of Canaan. The earliest recorded evidence of a people by the name of Israel appears in the Merneptah Stele of ancient Egypt, dated to about 1200 BCE. According to the modern archaeological account, the Israelites and their culture branched out of the Canaanite peoples and their cultures through the development of a distinct monolatristic—and later monotheistic—religion centred on the national god Yahweh.
Christian views on sinIn Christianity, 'sin' is an immoral act considered to be a transgression of divine law. The doctrine of sin is central to the Christian faith, since its basic message is about redemption in Christ. Hamartiology, a branch of Christian theology which is the study of sin, describes sin as an act of offence against God by despising his persons and Christian biblical law, and by injuring others. Christian hamartiology is closely related to concepts of natural law, moral theology and Christian ethics.
Apostolic successionApostolic 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 Anglican, Church of the East, Eastern Orthodox, Hussite, Moravian, Old Catholic, Oriental Orthodox, Catholic and Scandinavian Lutheran traditions maintain that "a bishop cannot have regular or valid orders unless he has been consecrated in this apostolic succession".
CreedA creed, also known as a confession of faith, a symbol, or a statement of faith, is a statement of the shared beliefs of a community (often a religious community) in a form which is structured by subjects which summarize its core tenets. The earliest known creed in Christianity, "Jesus is Lord", originated in the writings of Paul the Apostle. One of the most significant and widely used Christian creeds is the Nicene Creed, first formulated in AD 325 at the First Council of Nicaea to affirm the deity of Christ and revised at the First Council of Constantinople in AD 381 to affirm the trinity as a whole.
