Arianism is a Christological doctrine considered heretical by all modern mainstream branches of Christianity. It is first attributed to Arius, a Christian presbyter who preached and studied in Alexandria, Egypt. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before time by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time.
Pre-existence, preexistence, beforelife, or premortal existence, is the belief that each individual human soul existed before mortal conception, and at some point before birth enters or is placed into the body. Concepts of pre-existence can encompass either the belief that the soul came into existence at some time prior to conception or the belief that the soul is eternal. Alternative positions are traducianism and creationism, which both hold that the individual human soul does not come into existence until conception or later. It is to be distinguished from preformation, which is about physical existence and applies to all living things.
The Latin phrase extra Ecclesiam nulla salus is a phrase referring to a Christian doctrine about who is to receive salvation.
Nontrinitarianism is a form of Christianity that rejects the mainstream Christian theology of the Trinity—the belief that God is three distinct hypostases or persons who are coeternal, coequal, and indivisibly united in one being, or essence. Certain religious groups that emerged during the Protestant Reformation have historically been known as antitrinitarian.
In Christian theology, divinization, or theopoesis or theosis, is the transforming effect of divine grace, the spirit of God, or the atonement of Christ. Although it literally means to become divine, or to become God, most modern Christian denominations do not interpret the doctrine as implying an overcoming of a fundamental ontological difference between God and humanity; for example, John of the Cross indicated that while "God communicates to it [the individual soul] His supernatural Being, in such wise that it appears to be God Himself, and has all that God Himself has", yet "it is true that its natural being, though thus transformed, is as distinct from the Being of God as it was before".
God 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, Jesus Christ the Son, and the third person, God the Holy Spirit. Since the second century, Christian creeds included affirmation of belief in "God the Father ", primarily in his capacity as "Father and creator of the universe".
Novatianism or Novationism was an early Christian sect devoted to the theologian Novatian that held a strict view that refused readmission to communion of lapsi. The Church of Rome declared the Novatianists heretical following the letters of Saint Cyprian of Carthage and Ambrose wrote against them. Novatianism survived until the 8th century.
Novatian was a scholar, priest, and theologian. He is considered by the Catholic Church to have been an antipope between 251 and 258. Some Greek authors give his name as Novatus, who was an African presbyter.
In Christian hamartiology, eternal sin, the unforgivable sin, unpardonable sin, or ultimate sin is the sin which will not be forgiven by God. One eternal or unforgivable sin, also known as the sin unto death, is specified in several passages of the Synoptic Gospels, including Mark 3:28–29, Matthew 12:31–32, and Luke 12:10, as well as other New Testament passages including Hebrews 6:4–6, Hebrews 10:26–31, and 1 John 5:16.
God the Son is the second Person of the Trinity in Christian theology. According to Christian doctrine, God the Son, in the form of Jesus Christ, is the incarnation of the eternal, pre-existent divine Logos through whom all things were created. Although the precise term "God the Son" does not appear in the Bible, it serves as a theological designation expressing the understanding of Jesus as a part of the Trinity, distinct yet united in essence with God the Father and God the Holy Spirit.
Conceptions of God in classical theist, monotheist, pantheist, and panentheist traditions – or of the supreme deity in henotheistic religions – can extend to various levels of abstraction:
In Christianity, the Logos 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 the beginning was the Word, and the Word was with God, and the Word was God.
Perichoresis is the relationship of the three persons of the triune God to one another. The term was first used in Christian theology by the Church Fathers. The noun first appears in the writings of Maximus Confessor but the related verb perichoreo is found earlier in Gregory of Nazianzus. Gregory used it to describe the relationship between the divine and human natures of Christ as did John of Damascus, who also extended it to the "interpenetration" of the three persons of the Trinity, and it became a technical term for the latter. It has been given recent currency by such contemporary writers as Jürgen Moltmann, Miroslav Volf, John Zizioulas, Richard Rohr, and others.
Subordinationism is a Trinitarian doctrine wherein the Son is subordinate to the Father, not only in submission and role, but with actual ontological subordination to varying degrees. It posits a hierarchical ranking of the persons of the Social Trinity, implying ontological subordination of the persons of the Son and the Holy Spirit. It was condemned as heretical in the Second Council of Constantinople.
De Divisione Naturae is the title given by Thomas Gale to his edition (1681) of the work originally titled by 9th-century theologian Johannes Scotus Eriugena Periphyseon.
In Christianity, God is the eternal, supreme being who created and preserves all things. Christians believe in a monotheistic conception of God, which is both transcendent and immanent. Christians believe in a singular God that exists in a Trinity, which consists of three Persons: God the Father, God the Son, and God the Holy Spirit. Christian teachings on the transcendence, immanence, and involvement of God in the world and his love for humanity exclude the belief that God is of the same substance as the created universe but accept that God the Son assumed hypostatically united human nature, thus becoming man in a unique event known as "the Incarnation".
The Pneumatomachi, also known as Macedonians or Semi-Arians in Constantinople and the Tropici in Alexandria, were an anti-Nicene Creed sect which flourished in the regions adjacent to the Hellespont during the latter half of the fourth, and the beginning of the fifth centuries. They denied the godhood of the Holy Ghost, hence the Greek name Pneumatomachi or 'Combators against the Spirit'.
Debate exists as to whether the earliest Church Fathers in Christian history believed in the doctrine of the Trinity – the Christian doctrine that God the Father, the Son and the Holy Spirit are three distinct persons sharing one homoousion (essence).
In Christianity, heaven is traditionally the location of the throne of God and the angels of God, and in most forms of Christianity it is the abode of the righteous dead in the afterlife. In some Christian denominations it is understood as a temporary stage before the resurrection of the dead and the saints' return to the New Earth.
The position of the Eastern Orthodox Church regarding the Filioque controversy is defined by their interpretation of the Bible, and the teachings of the Church Fathers, creeds and definitions of the seven Ecumenical Councils, as well as the decisions of several particular councils of the Eastern Orthodox Church.
