The term was brought forward and used at the Council of Nicaea as the result of great dogmatic activity, in the endeavor to find in his consubstantiality (homoousios) with the Father a suitable expression for the idea of the divinity of the Logos.
Bulgakov argues that the Nicene homoousios was a dogmatic innovation — unscriptural in origin — driven by the theological necessity of asserting the full divinity of the Logos against subordinationist readings.
