Modalists like Sabellius historically accepted that Father, Son, and Spirit are numerically identical with God while denying tritheism, showing a coherent trinitarian-adjacent position exists.

Reasons For

1 perspective

Reason for

1.Numerical identity allows multiple distinct roles/modes without multiplying divine substances, avoiding polytheism while preserving biblical personhood language.
?
Think about whether this reason is strong or weak
2.Modalism's coherence demonstrates that non-Nicene trinitarian positions need not collapse into either strict unitarianism or illogical tritheism.
?
Think about whether this reason is strong or weak
3.Historical modalists maintained orthodox monotheism while accommodating New Testament passages depicting Father, Son, and Spirit as distinct agents.
?
Think about whether this reason is strong or weak

Reasons Against

1 perspective

Reason against

1.Numerical identity doctrine faces the logical problem: if Father and Son are numerically identical to God, they must share all properties—yet differ in suffering, knowledge, or location.
?
Think about whether this reason is strong or weak
2.Biblical texts describe simultaneous Father-Son distinctions (baptism scene, 'not my will but yours') that modalism struggles to preserve without collapsing identity.
?
Think about whether this reason is strong or weak
3.Modalism requires treating 'Father,' 'Son,' 'Spirit' as mere masks or phases rather than real distinctions, straining the coherence of biblical relational language.
?
Think about whether this reason is strong or weak

Key Terms

Modalists(as used in theology and philosophy of religion): Philosophers who believed that God exists in different modes or forms (Father, Son, Holy Spirit) rather than as three separate beings, kind of like how water can be ice, liquid, or steam but is still H2O.
Numerically identical(as used to describe whether two agents are the exact same person): Being literally the same thing, not just similar or alike—like how the person you are today is numerically identical to the person you were yesterday (one and the same individual).
Sabellius(as a historical theological figure): An early Christian theologian (around 200 AD) who argued that God appeared in different ways at different times rather than existing as three distinct persons simultaneously.
Trinitarian(as used in Christian theology): Related to the Christian doctrine of the Trinity, which holds that God is one being existing as three persons: Father, Son, and Holy Spirit.
coherent(de Finetti's usage in the context of the Dutch Book argument for probabilism): A subject is coherent if their unconditional degrees of belief do not permit a Dutch Book (a guaranteed loss through a combination of bets) to be made against them
tritheism(Eastern Christian theological controversy; distinguished from the self-understanding of thinkers like Philoponus who denied abandoning monotheism): A hostile label applied to theologians who, in attempting to make the mystery of the Trinity philosophically intelligible, concluded that the three Persons of the Trinity are three distinct divine substances — not a self-description adopted by those so labeled
