NeoplatonismNeoplatonism is a version of Platonic philosophy that emerged in the 3rd century AD against the background of Hellenistic philosophy and religion. The term does not encapsulate a set of ideas as much as a series of thinkers. Among the common ideas it maintains is monism, the doctrine that all of reality can be derived from a single principle, "the One". Neoplatonism began with Ammonius Saccas and his student Plotinus (c. 204/5–271 AD) and stretched to the 6th century AD.
Christian theologyChristian theology is the theology of Christian belief and practice. Such study concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument.
Hypostatic unionHypostatic union (from the Greek: ὑπόστασις hypóstasis, "person, subsistence") is a technical term in Christian theology employed in mainstream Christology to describe the union of Christ's humanity and divinity in one hypostasis, or individual personhood. The most basic explanation for the hypostatic union is Jesus Christ being both fully God and fully man. He is both perfectly divine and perfectly human and has two complete and distinct natures at once.
NousNous, or Greek νοῦς (UKnaʊs, USnuːs), sometimes equated to intellect or intelligence, is a concept from classical philosophy for the faculty of the human mind necessary for understanding what is true or real. Alternative English terms used in philosophy include "understanding" and "mind"; or sometimes "thought" or "reason" (in the sense of that which reasons, not the activity of reasoning). It is also often described as something equivalent to perception except that it works within the mind ("the mind's eye").
ProsoponProsopon (UKˈprɒsəpɒn, USprəˈsoʊ-; from πρόσωπον prósōpon; plural: πρόσωπα prósōpa) is a theological term used in Christian theology as designation for the concept of a divine person. The term has a particular significance in Christian Triadology (study of the Trinity), and also in Christology. In English language, the form prosopon is used mainly in scholarly works, related to theology, philosophy or history of religion, while it is also commonly translated as person, both in scholarly or non-scholarly writings.
MiaphysitismMiaphysitism is the Christological doctrine that holds Jesus, the "Incarnate Word, is fully divine and fully human, in one 'nature' (physis)." It is a position held by the Oriental Orthodox Churches and differs from the Chalcedonian position that Jesus is one "person" (ὑπόστασις) in two "natures" (φύσεις), a divine nature and a human nature (Dyophysitism). While historically a major point of controversy within Christianity, several modern declarations by both Chalcedonian and Miaphysite churches state that the difference between the two Christological formulations does not reflect any significant difference in belief about the nature of Christ.
OusiaOusia (ˈuːziə,_ˈuːsiə,_ˈuːʒə,_ˈuːʃə; οὐσία) is a philosophical and theological term, originally used in ancient Greek philosophy, then later in Christian theology. It was used by various ancient Greek philosophers, like Plato and Aristotle, as a primary designation for philosophical concepts of essence or substance. In contemporary philosophy, it is analogous to English concepts of being and ontic. In Christian theology, the concept of θεία ουσία (divine essence) is one of the most important doctrinal concepts, central to the development of trinitarian doctrine.
Church of the EastThe Church of the East ( ʿĒḏtā d-Maḏenḥā) or the East Syriac Church, also called the Church of Seleucia-Ctesiphon, the Persian Church, the Assyrian Church, the Babylonian Church or the Nestorian Church, was an Eastern Christian church of the East Syriac Rite, based in Mesopotamia. It was one of three major branches of Eastern Christianity that arose from the Christological controversies of the 5th and 6th centuries, alongside the Oriental Orthodox Churches and the Chalcedonian Church.
PhysisFusis, Phusis or Physis (ˈfaɪˈsɪs; φύσις phýsis) is a Greek philosophical, theological, and scientific term, usually translated into English—according to its Latin translation "natura"—as "nature". The term originated in ancient Greek philosophy, and was later used in Christian theology and Western philosophy. In pre-Socratic usage, physis was contrasted with νόμος, nomos, "law, human convention".
TrinityThe Christian doctrine of the Trinity (Trinitas, from trinus 'threefold') is the central doctrine concerning the nature of God in most Christian churches, which defines one God existing in three , , consubstantial divine persons: God the Father, God the Son (Jesus Christ) and God the Holy Spirit, three distinct persons (hypostases) sharing one essence/substance/nature (homoousion) As the Fourth Lateran Council declared, it is the Father who s, the Son who is , and the Holy Spirit who proceeds.
