NicäaKonstantinopolitanum

NicäaKonstantinopolitanum refers to a significant doctrinal formula that emerged from the councils of Nicaea (325 AD) and Constantinople (381 AD). The First Council of Nicaea was convened to address the Arian controversy, which questioned the divinity of Jesus Christ. The Nicene Creed, formulated at this council, affirmed the Son's full divinity, stating that Jesus Christ is "true God from true God, begotten, not made, consubstantial with the Father."

However, theological debates continued, leading to the First Council of Constantinople. This council reaffirmed the Nicene Creed and further clarified Christological doctrines, particularly regarding the Holy Spirit. The Council of Constantinople expanded the Nicene Creed, adding clauses that affirmed the divinity of the Holy Spirit and His role as the "Lord, the giver of life, who proceeds from the Father."

The NicäaKonstantinopolitanum, therefore, represents a foundational statement of Christian orthodoxy concerning the nature of God as Trinity: one God in three co-equal and co-eternal persons – Father, Son, and Holy Spirit. This creed became a cornerstone of Christian belief and worship for many denominations, particularly within Eastern Orthodoxy and Roman Catholicism, and influenced the development of Protestant creeds. Its theological pronouncements have been debated and interpreted throughout Christian history but remain a pivotal articulation of Trinitarian doctrine.
