Key Terms to Review (22)
Adoptionist heresy: Adoptionist heresy is the belief that Jesus Christ was not divine by nature but became divine at a specific point in time, often associated with his baptism or resurrection. This view implies that Jesus was merely a human who was adopted by God, contradicting the orthodox Christian teaching of the pre-existence and full divinity of Christ. This heresy played a significant role in shaping early Christian discussions about the nature of Christ and contributed to the historical development of Trinitarian theology.
Arianism: Arianism is a Christian theological doctrine that asserts that Jesus Christ, the Son of God, is distinct from and subordinate to God the Father. This belief emphasizes that Christ was created by the Father and therefore not co-eternal or consubstantial with Him, which sparked significant theological debates in early Christianity and influenced the development of Trinitarian theology.
Athanasius: Athanasius was a prominent early Christian theologian and bishop of Alexandria, best known for his role in the development of Trinitarian theology and his staunch opposition to Arianism. His theological writings and defense of the Nicene Creed were pivotal in shaping the early understanding of the nature of Christ and the Trinity, establishing foundational ideas that influenced the Christian faith significantly.
Augustine's De Trinitate: Augustine's De Trinitate is a theological work written by Saint Augustine in the early 5th century that explores the nature of the Holy Trinity. In this work, Augustine seeks to articulate a coherent understanding of the relationship between the Father, Son, and Holy Spirit, emphasizing their unity and distinctiveness. This text is significant in the historical development of Trinitarian theology as it provides one of the earliest comprehensive examinations of the Trinity, which has influenced Christian thought for centuries.
Cappadocian Fathers: The Cappadocian Fathers were three influential theologians from the region of Cappadocia in modern-day Turkey during the 4th century, who played a pivotal role in shaping early Christian thought, especially in relation to the doctrine of the Trinity. They are known for their theological insights that helped clarify the nature of God as three distinct persons in one essence, addressing various heresies that challenged the understanding of the Trinity. Their contributions laid foundational groundwork for both Eastern Orthodox theology and later Christian doctrine.
Consubstantiality: Consubstantiality refers to the theological concept that the three persons of the Holy Trinity—Father, Son, and Holy Spirit—are of the same substance or essence. This idea emphasizes the unity and co-equality of the three divine persons, affirming that while they are distinct, they share the same divine nature, which is foundational to understanding the Christian conception of God as a Trinity.
Council of Nicaea: The Council of Nicaea, held in 325 CE, was the first ecumenical council of the Christian Church and aimed to address various theological disputes, particularly concerning the nature of Christ and the relationship between God the Father and Jesus Christ. This council marked a significant moment in shaping early Christian doctrine, especially regarding Trinitarian theology, and set a precedent for future councils in resolving theological conflicts.
Economic Trinity: The Economic Trinity refers to the distinct roles and activities of the three persons of the Trinity—Father, Son, and Holy Spirit—within the context of God's actions in history, particularly in relation to creation, redemption, and sanctification. This concept emphasizes how each person of the Trinity participates in the divine plan while maintaining their unique roles, showing how their interactions reveal God's character and purpose in the world.
Father: In Christian theology, 'Father' primarily refers to God the Father, the first person of the Holy Trinity. This term signifies a personal relationship between God and believers, embodying attributes of love, authority, and care. The concept of God as Father is central to understanding core beliefs in Christianity, shaping the identity of God within the faith and influencing how followers perceive their relationship with the divine.
Filioque Controversy: The filioque controversy centers on the phrase 'and the Son' which was added to the Nicene Creed by the Western Church, asserting that the Holy Spirit proceeds from both the Father and the Son. This theological debate has significant implications for the understanding of the Trinity and has contributed to the divide between Eastern Orthodoxy and Western Christianity, particularly regarding the nature of the Holy Spirit's relationship within the Godhead.
First Council of Constantinople: The First Council of Constantinople, convened in 381 AD, was the second ecumenical council of the Christian Church that aimed to address and clarify issues regarding the nature of the Holy Spirit and the ongoing Arian controversy. This council played a crucial role in shaping Trinitarian theology by affirming the divinity of the Holy Spirit and solidifying the Nicene Creed established at the First Council of Nicaea in 325 AD, thus further developing foundational Christian beliefs about the Trinity.
Holy Spirit: The Holy Spirit is the third person of the Trinity in Christian belief, representing God's presence and action in the world. This aspect of God is seen as a comforter, guide, and source of inspiration for believers, playing a crucial role in individual and communal faith experiences.

Perichoresis: Perichoresis is a theological term that describes the interpenetration and mutual indwelling of the three persons of the Trinity: Father, Son, and Holy Spirit. This concept emphasizes the unity and relational dynamics within the Godhead, highlighting how each person fully participates in the life and essence of the others without losing their distinct identities. It also serves to illustrate the communal nature of God, which underpins core beliefs and has shaped historical developments in understanding the Trinity.
Pneumatomachian Controversy: The Pneumatomachian Controversy refers to a theological dispute in the early Christian church regarding the nature and status of the Holy Spirit, specifically whether the Holy Spirit was truly divine or a created being.

The idea suggests that God’s essence is inherently social, which impacts various areas of theology including salvation, creation, and ecclesiology.
Son: In Christian theology, the term 'Son' primarily refers to Jesus Christ, who is considered the second person of the Trinity.

Tritheism: Tritheism is the theological belief that the Trinity consists of three separate and distinct gods rather than three persons within one God. This concept emphasizes a plurality of divine beings, which stands in contrast to mainstream Christian teaching about the nature of God as a unified entity in three coequal persons: the Father, the Son, and the Holy Spirit. Tritheism has been historically significant in discussions about the nature of God and the development of Trinitarian theology.
