Declaration of Faith, in Latin and the Original Greek

A concise yet profound statement of early Christian belief, this work presents a creed written side‑by‑side in Latin and its original Greek. Its author, a leading bishop who helped shape the First Council of Nicaea, composed it as a clear response to the theological controversies of his time, especially the Arian challenge to Christ’s divinity.

The declaration affirms a single, uncreated Father and a Son who is “of one essence” with Him, emphasizing that the Son is not a created being but the eternal Logos who became flesh for humanity’s salvation. It also affirms the Holy Spirit’s role and rejects any notions that separate the three persons of the Trinity into distinct substances, offering a vivid theological picture of the Father‑Son relationship as a single, indivisible flow of divine life.

Listening to this text provides a rare glimpse into the language and reasoning that defined orthodoxy in the fourth century. The bilingual presentation lets modern ears hear the rhythm of the original Greek alongside its Latin translation, deepening appreciation for the early church’s struggle to articulate the mystery of the divine.
