The belief that Jesus and God are the same person with a different essence is called Modalism. This view holds that God is one being who manifests himself in different modes or forms, one of which is Jesus Christ. It contrasts with the Trinitarian view, which posits that God exists eternally as three distinct persons (Father, Son, and Holy Spirit) in one divine being. Here are some reasons why this should be rejected:
1. Contradiction with Scripture:
Interactions between Persons: The Bible depicts distinct interactions between the Father, Son, and Holy Spirit. For example, Jesus prays to the Father, the Father sends the Son, and the Holy Spirit descends upon Jesus at his baptism. Modalism struggles to explain these passages convincingly, as it would imply God is essentially interacting with different aspects of himself, which is seen as illogical and contrary to the relational nature of God presented in scripture.
Simultaneous Presence: Events like Jesus' baptism (Matthew 3:16-17) portray all three "modes" simultaneously present, contradicting the modalist idea of sequential manifestation.
Personhood of the Holy Spirit: Scripture attributes personal characteristics like will, emotions, and mind to the Holy Spirit, suggesting a distinct personhood rather than just a divine force or mode.
2. Undermining Key Christian Doctrines:
The Incarnation: Modalism blurs the distinction between Father and Son, diminishing the unique significance of the Son's incarnation and redemptive work. The core belief is that the Son of God, a distinct person, took on human nature to redeem humanity, which Modalism undermines by suggesting the Son is merely a mode.
The Atonement: If the Father and Son are the same person, then the concept of God sending his Son to die for humanity loses its meaning. The sacrifice becomes God essentially sacrificing himself to himself, which contradicts the relational aspect of the atonement in orthodox Christianity.
Patripassianism: An implication of Modalism is that the Father suffers, or Patripassianism. This is because Modalism doesn't differentiate between the Father and the Son, suggesting the Father suffered on the cross, which contradicts the orthodox belief that only the Son suffered in his humanity.
3. Historical Rejection:
Modalism was condemned as a heresy by early church councils (with a near unanimous vote from pastors from diverse locations throughout the empire) like the Council of Nicaea (325 AD), which affirmed the Trinitarian doctrine of God as one essence in three distinct persons. This rejection highlights the historical consensus within Christianity against modalism.
Any attempt to characterize the nature of Jesus must include the bible's description of BOTH the nature of man AND the nature of God. This chart and scripture references illuminate these distinctions and characteristics :
