National Association of Christian Ministers Summary Series: Theology


Christian consubstantiality is a theological term used to describe the belief that the three persons of the Christian Trinity – Father, Son (Jesus Christ), and Holy Spirit – share the same divine substance or essence. The term is related to the concept of homoousia, which means “of the same substance,” and was developed in response to the Arian controversy in the fourth century.

The idea of consubstantiality emphasizes the unity and equality of the Trinity, while also acknowledging the distinctiveness of each person. The Father, Son, and Holy Spirit are understood to be one God, with each person playing a unique role in the Godhead. This doctrine is often referred to as the doctrine of the Trinity.

The concept of consubstantiality is an essential belief for orthodox Christians and is included in the Nicene Creed, which states that the Father, Son, and Holy Spirit are “of one substance (consubstantial) with the Father.”

Overall, Christian consubstantiality is a central component of Christian theology, emphasizing the unity and diversity of the Trinity and the divine nature of Jesus Christ.
