For most of the twentieth century, analytic philosophy of religion largely passed over the monarchy of the Father. Debates about the Trinity tended to assume, often without argument, that "God" simply names the Trinity as a whole — three co-equal persons considered together — rather than asking whether the patristic consensus surveyed in this study's second part had a specific, defensible structure worth taking seriously on its own terms. That has changed. Two recent philosophers in particular have made the doctrine a live option again.
Branson: a neglected doctrine, recovered
Philosopher Beau Branson's 2022 article "One God, the Father: The Neglected Doctrine of the Monarchy of the Father, and Its Implications for the Analytic Debate about the Trinity" makes the historical case directly: this was the dominant patristic position, and modern analytic theology's habit of treating "God = the Trinity" as the default has been arrived at more by omission than by argument. Branson's own account holds, in its strongest form, that the one true God simply is the Father — numerically identical to him — even while the Son and Spirit are also, fully and without qualification, divine. He shows that this claim, rather than being a fringe or eccentric position, is compatible with a wide range of the analytic models already on the table for making sense of three-in-one.
Sijuwade: does the monarchy demote the Son and Spirit?
The theologian Joshua Sijuwade — whose reformulated argument from love for the Trinity's necessity appears elsewhere in this collection of studies — has approached the monarchy from a different angle in his 2022 article "Building the monarchy of the Father," published in the journal Religious Studies. His starting point is the most serious objection the doctrine faces: if the Son and Spirit depend on the Father for their existence — even eternally, even without any point at which they didn't exist — doesn't that dependency amount to a kind of ontological inferiority? Isn't "derived from" just a more polite way of saying "less than," which is exactly the ground on which the fourth century condemned Arianism?
Sijuwade's answer borrows a tool from contemporary metaphysics rather than from historical theology directly: philosopher Karen Bennett's framework of "building," a general relation covering the many ways one thing can depend on and be produced by another — composing, constituting, grounding, or causing it — without that dependence relation, on its own, telling you anything about relative rank or value. A statue depends on the clay that constitutes it, but the statue is not thereby a "lesser" or "inferior" thing than the clay; the dependence is real, and it carries no verdict about worth. Applying this framework to the Trinity, Sijuwade argues that the Father's role as the one who eternally "builds" the Son and Spirit — as their sole source — is a claim about the direction of dependence between them, not a claim that either is somehow less fully, less completely, or less perfectly divine than the Father. The three share one undivided nature; what the Father alone has, that the other two do not, is the property of being underived — a genuine asymmetry, but one that Sijuwade argues does not touch, still less diminish, the equality of what they all three are.
This is, in substance, the same move Tertullian, Athanasius, and Basil were already making in the second and fourth centuries, explored in the second study in this series — but Sijuwade gives it a modern metaphysical vocabulary precise enough to be tested against contemporary objections the fathers never had occasion to answer. The conclusion he reaches is the same one the pro-Nicene fathers reached: the monarchy of the Father is not in tension with the full, co-equal deity of the Son and Spirit. It is what makes their unity as one God intelligible in the first place, rather than an unexplained fact asserted and left there.
Why this doctrine is already at work elsewhere on this site
This is not an isolated curiosity. The study "Love and the Necessity of the Trinity" elsewhere in this collection — also drawing on Sijuwade's work — explicitly builds its entire argument on this same foundation: it names "God" as a single divine person (the Father), rather than the Trinity considered collectively, precisely because the monarchy of the Father is the more defensible starting point for asking what a single divine person's perfect love would necessarily produce. Read together, the two studies show the same doctrine doing two different kinds of work: here, patristic and historical — establishing why the fathers thought monotheism required it; there, philosophical — using it as the premise from which the necessity of three persons can be derived at all.
Why it matters
A doctrine that shaped how the fathers defended monotheism against tritheism, that helped split the church for a thousand years over a single Latin word, and that is now being defended again with the tools of contemporary metaphysics is not a historical curiosity to be filed away. The monarchy of the Father is one answer — argued for across seventeen centuries by people who took both the unity of God and the full divinity of the Son and Spirit with total seriousness — to the hardest question the doctrine of the Trinity ever has to face: how three can be, without remainder or evasion, one.
