The Nicene Creed was originally formulated at which ancient council?

• A. Council of Nicaea
• B. Council of Trent
• C. First Council of Constantinople
• D. Council of Ephesus

Answer: (A)

This question is about the origin of the Nicene Creed. It was first formulated at the Council of Nicaea in 325 CE, convened by Emperor Constantine to address a major dispute about who Jesus is in relation to God the Father. The council produced a clear statement of belief that affirmed Jesus’ divinity as being of the same essence as the Father, using the term homoousios to express that unity of substance. The name “Nicene” comes from the city where this gathering took place, Nicaea. Later, the creed was expanded at the First Council of Constantinople in 381, but the original formulation—the one that established the basis for the Nicene Creed—came from Nicaea. The other councils mentioned addressed different issues or occurred later: Trent dealt with reforms during the Protestant era; Ephesus focused on Christology and Mary, and Constantinople expanded the creed but did not originate it.
