Was God always loving? If yes, he eternally had an object of his love. If the only eternal being was solitary, then either the love was directed at nothing (incoherent), at creation (which is not eternal), or back at the self (which collapses into self-love). The Trinity answers the question metaphysically: the Father has eternally loved the Son in the Spirit. John 17:24 — Jesus prays Father, you loved me before the foundation of the world. The Christian claim is not that Tawhid, unitarianism, or deism are immoral; it is that they cannot ground eternal love as a feature of God's nature. They make love a contingent attribute God exhibits toward creation, not a necessary feature of who God is. The question matters because 1 John 4:8 — God is love — is either an essential statement about God's eternal nature or a description of his behaviour in time. The Trinity is the only major monotheism in which the first option is metaphysically grounded.
The four monotheisms compared
Compare four major monotheistic positions on the question Was God always loving?
Tawhid (Sunni Islam)
Classical Tawhid is unwavering oneness. Allah is one in essence (dhāt) and has multiple attributes (ṣifāt) — knowledge, power, will, mercy, love. He is al-Wadūd (the Loving One, Q 11:90, Q 85:14).
The classical Sunni theological position holds the ṣifāt are eternal attributes of Allah, distinct from his essence but not separable from it. The Ashʿarī and Salafī positions affirm this clearly; the Muʿtazila held a more austere view that risked collapsing the attributes into the essence.
The question for Christian engagement: toward what or whom did Allah eternally exhibit his eternal attribute of love? Before creation, there was no creation to love. The classical Sunni answer is one of:
- Allah loves himself. The verse Q 5:54 speaks of those whom Allah loves and who love him — but this is contingent on the believer existing. The eternal al-Wadūd attribute, on this reading, is exhibited eternally toward Allah's own perfection.
- Eternal attributes do not require an eternal object. The attribute of love is part of who Allah is in the way knowledge is — and just as Allah's eternal knowledge does not require eternal objects of knowledge (he can know contingent truths timelessly without those truths being eternal), his eternal love does not require eternal objects.
- Mystery. The classical Ashʿarī tradition often appealed to bilā kayf (without [asking] how) — accepting the doctrine without resolving the metaphysical question.
Each response is intellectually serious. None grounds eternal love between persons in the way Christianity does.
Trinity (Christian)
The Christian answer: the Father has eternally loved the Son, and the Son the Father, in the Holy Spirit. This is not a metaphor. It is a metaphysical claim that the divine being is eternally relational. Love is not an attribute Allah has; it is what God is, in the eternal relation of the persons.
John 17:24 — Father, you loved me before the foundation of the world. John 17:5 — the glory I had with you before the world existed. Ephesians 1:4 — He chose us in him before the foundation of the world. The Christian claim grounds eternal love in eternal relation.
Richard of St Victor's De Trinitate (12th c.) makes the argument explicitly: the highest love is mutual love, and mutual love requires a plurality of persons. On Richard's reading, God is love metaphysically requires the Trinity. The doctrine is not arbitrary speculation; it is the only metaphysics on which God is love is an eternal essential truth.
Unitarianism (Jewish, Socinian, Jehovah's Witness)
Jewish monotheism affirms one God; the rabbinic and modern Jewish positions on God's love are similar to Tawhid in not affirming intra-divine relations. Socinian Christianity (16th c.) and modern Jehovah's Witness theology hold one-person monotheism while honouring Jesus as Messiah without affirming his divinity. The same metaphysical question applies: toward whom did God eternally love?
Jewish theology has historically been comfortable with mystery on this point and often emphasises God's love for Israel and his attribute of ḥesed (lovingkindness). It has not classically grounded eternal love metaphysically.
Deism
Classical deism (Voltaire, Jefferson) holds a creator God who set the universe in motion and does not relate to creation personally. On deism, the question was God always loving? is largely unanswerable — the deistic God is not characterised by personal attributes that could be eternal.
Deism is the least satisfying answer to the question. It dispenses with the question by dispensing with the relevant attribute.
Why the Christian answer matters
The metaphysical asymmetry has real implications.
Implication 1: God is love by nature, not by act
On Christianity, God is love is an essential statement about what God is — the eternal relation of the persons. Allah's love, on the most rigorous classical Sunni statement, is an attribute he has, expressed toward objects he creates. The Christian metaphysics does not require God to make creatures in order to be loving; the Islamic metaphysics, on most readings, does — Allah's love-toward-something only finds an object when there is something to love.
This is not a charge against Allah's character. It is an observation about what kind of statement Allah loves is on Tawhid versus what kind of statement God is love is on Christianity.
Implication 2: Why creation
On Tawhid, creation is needed for Allah to express his attribute of love (or other relational attributes — mercy, generosity, etc.). The classical Sufi tradition has spoken of creation as Allah's hidden treasure he wished to make known (see the famous ḥadīth qudsī). On this reading, Allah created in some sense for a relational purpose his eternal solitude could not fulfil.
On Christianity, creation is not needed for divine love. The Father, Son, and Spirit are eternally fulfilled in their mutual love. Creation is therefore gratuitous — a free overflow of the love that already exists, not a metaphysical necessity. This is what Christian theology calls the bonum diffusivum sui — the good is by nature self-diffusing. Creation is the spillover of an inner divine joy.
This difference shapes how each tradition reads the relationship between creator and creation. On Christianity, you and I exist because the Father, Son, and Spirit wanted to share their love. On Tawhid, you and I exist because Allah willed it for his sovereign purposes — which the classical theologians describe variously, but with less of the internal-overflow character.
Implication 3: The cross
The cross is unintelligible without intra-divine love. Why did the Father send the Son? On unitarianism or strict Tawhid, the question is hard; on Trinitarianism, it is the most natural thing in the world. The eternal Son loves the Father with the Spirit; in the cross the Son obeys the Father unto death; the Father raises the Son in the Spirit; the love that has eternally circulated within God now opens to include those whom the Son brings in.
Romans 5:5-8: God's love has been poured into our hearts through the Holy Spirit who has been given to us... God shows his love for us in that while we were still sinners, Christ died for us. The cross is the eternal Father-Son love spilling outward to enemies. There is no analogue in Tawhid because the metaphysics of intra-divine relational love is not there to spill.
The strongest Muslim response
Three things to engage carefully when this conversation comes up.
"Allah is al-Wadūd. He is loving by nature." Q 11:90, Q 85:14. The Christian engager grants this and asks the further question: toward whom did Allah eternally exhibit al-Wadūd before creation? The classical Sunni answer is one of the three options surveyed above, none of which gives the intra-divine relational answer Trinitarianism does. The Muslim friend may answer that Allah's love-essence does not require an object — the Christian counter is that love by nature is hard to make sense of without the loved being part of what love even means.
"This is just Christian metaphysics imported into a question Tawhid does not need to answer." Partially fair — different metaphysical traditions have different priorities. The Christian counter: Christianity is asking a question every classical theologian has wrestled with (the relation of the eternal attributes to the eternal essence is the central problem of classical Sunni kalām). The Christian is not inventing a new question; he is offering a different answer to a question Sunni kalām has wrestled with for a thousand years.
"The Trinity is too speculative; we should not say of God what he has not said of himself." This is the classical Ashʿarī bilā kayf posture, and it is admirable. The Christian counter: Christians are not claiming to have figured out God by reason; they are reading what God has said about himself in the incarnation of Christ. The Trinity is revealed, not speculated. The Christian claim is that God has revealed himself as Father-Son-Spirit in the gospel — and that what is revealed is that he has eternally been Father-Son-Spirit.
A note for the Christian engager
This is the deepest, longest-running, and most fruitful Christian-Muslim conversation. It does not turn on a quick argument; it grows over months of friendship and shared reading. The thoughtful Muslim friend often finds the eternal love argument compelling at the level of intuition long before he can explore the metaphysics. Many Muslims who became Christians point to the slow conviction that the Father loves the Son gives them a God they can rest in — not just submit to.
Land always on Christ. The Father's love for the Son, made visible in the incarnation and the cross, is the destination of every comparative-monotheism conversation.
Working analogies for conversation
Three working analogies for the eternal love requires eternal plurality point — useful in casual conversation, all of them imperfect.
The relational analogy. A man who has never loved anyone is not yet "loving" in any deep sense. Love-in-the-abstract is not love. This appeals to ordinary moral intuition. The Christian engager extends: if love requires the loved, and God is eternally love, then God eternally has the loved. The Trinity supplies this without making creation eternal.
The communicative analogy. Speech requires a hearer. The Father has eternally spoken his Word (the Son) in the Spirit. John 1:1 frames the Son as the Word — God's eternal self-communication. A purely solitary God would be eternally silent — not sharing himself, not communicating, not relating. The Trinity is God who has eternally been speaking himself.
The musical analogy. Music requires harmony — multiple notes in relation. A single sustained tone is not yet music. The Trinity is the eternal harmony of three voices in one melody. Solitary monotheism is the sustained tone — present, but not yet song. (This analogy belongs to the Christian devotional tradition more than the academic; use it lightly.)
None of these analogies proves the Trinity. They communicate, in everyday language, why eternal love and eternal plurality might naturally go together — and why the Trinity gives us a metaphysics in which God is love is more than a statement about behaviour toward us.

How to think about it
- Lead with the question, not the answer. Was God always loving? invites the Muslim friend into a question, not an attack.
- Honour the classical Sunni ṣifāt debate. Tawhid is not naive on this; engage it at the level Ashʿarī and Salafī scholars have engaged it.
- Show why eternal love seems to require eternal plurality. Richard of St Victor's argument is intuitive and ancient.
- Note the implications. Why creation, why the cross, why God is love — three places the Trinitarian metaphysics shows its work.
- Land on the cross. The Father-Son eternal love spilling out to enemies in Romans 5:5-8 is the gospel destination of this whole conversation.
Common objections
- Allah is *al-Wadūd* — the Loving One. He doesn't need a Trinity for that.
He is, and Christians grant this. The further question is toward whom Allah is al-Wadūd eternally. The classical Sunni theological tradition gave several answers — Allah loves himself, eternal attributes don't require eternal objects, bilā kayf. Each is intellectually serious. None grounds intra-divine relational love in the way Christianity does. The Christian's question is whether the Muslim friend finds the classical answers fully satisfying or whether the Trinitarian alternative — eternal Father-Son-Spirit love — is at least worth weighing.
- This sounds like Christian metaphysics importing Christian categories.
It is Christian metaphysics. Every metaphysics is some metaphysics. The classical Islamic kalām tradition was deeply influenced by Greek philosophical categories (the Muʿtazila were the most explicit about it). The honest comparative move is not to pretend either tradition has no metaphysics — it is to ask which metaphysics gives a more coherent account of God is love.
- Couldn't God just be eternally loving toward himself?
Self-love is a real category, but it is normally distinguished from love between persons. When the Christian tradition says God is love, it specifically means the love between Father, Son, and Spirit — interpersonal love. Self-love is the kind a solitary being can exhibit; interpersonal love requires more than one person. The Christian claim is that love between persons is the deeper kind, and that is what the Trinity grounds eternally.
- Doesn't this just push the difficulty back? You still have one God who somehow is also three.
Yes — and the difficulty is the doctrine, not a bug. The Trinity is mystery. It is not contradiction (see Philosophical defenses of the Trinity) but it is mystery. The Christian claim is not that the Trinity is easy but that it is the truth God has revealed about himself in Christ. We hold it because Jesus said the Father loved me before the foundation of the world (John 17:24) — and because that statement, taken seriously, points to a God who has eternally been love. The doctrine is what we have because of Christ.
