“Embrace the God who is love, and you will embrace God through love.” — Saint Augustine, De Trinitate, VIII, 8, 12
Nota Bene :
Le concept d’Alter-unité que je mobilise ici est, à ma connaissance, une invention personnelle. Il ne prétend pas remplacer la terminologie traditionnelle de l’Église, mais proposer une clé d’intelligibilité nouvelle, adaptée à notre époque. La Trinité est sans doute l’un des mystères les plus vertigineux de la foi chrétienne — difficile non seulement pour ceux qui la découvrent, mais aussi pour les catholiques eux-mêmes. Elle touche, à mon sens, la frontière même entre la raison et la foi, entre ce qui est encore concevable, et ce qui, tout en étant vrai, dépasse radicalement nos catégories humaines.
Nota Bene:
The concept of Alter-unity that I introduce here is, to my knowledge, a personal invention. It does not claim to replace the Church's traditional terminology, but rather to offer a new key of intelligibility suited to our times. The Trinity is undoubtedly one of the most dizzying mysteries of the Christian faith — difficult not only for those discovering it, but even for Catholics themselves. It touches, in my view, the very frontier between reason and faith, between what is still conceivable and what, though true, radically transcends all human categories.
Introduction:
Not all religious conceptions are equal. To state this frankly is neither contemptuous nor arrogant: it is an act of fidelity to what Christian Revelation uniquely offers the world. For while all traditions pose profound questions, few dare this earth-shaking audacity: to affirm that at the heart of the one God, there is relationship.
This is the mystery that the Christian faith calls the Trinity. Not a God with three masks, nor three gods in harmony, but one God — living, vibrant, loving — in three distinct and inseparably united Persons: the Father, the Son, the Spirit. This mystery is not a riddle to be solved, but a source to be contemplated, and a light upon what it means to be: to be oneself, before another, and yet united without confusion. To express this, I propose here a personal concept: that of Alter-unity. It is not yet another esoteric jargon, but an attempt to restate — in today's words — what the Christian tradition has taught from the beginning: that God is unity in otherness, love in distinction, communion without fusion.
In contrast with modern spiritualities that advocate the dissolution of the self into the All, the abandonment of the mind or the extinction of desire, Christian faith dares to assert that man is made for relationship — because he is created in the image of a God who is relationship. And that happiness is not found in the loss of self, but in the welcome of the other.
The Trinity is not a dogmatic abstraction, it is a promise: that true love is possible, because it exists first within God himself.
God is Relationship: The Trinity as the Foundation of Alter-unity
Christian faith does not begin with an idea, but with an encounter: the encounter with Christ, who speaks of the Father, who sends the Spirit. From its very beginning, the Church has proclaimed that God is not a solitary being, but a living relationship. Pater non est Filius, nec Filius est Spiritus Sanctus — the Father is not the Son, nor is the Son the Holy Spirit. And yet, unus Deus: one single God.
1.1 – One God in Three Persons
The Trinitarian mystery declares this with a boldness that cannot be reduced to formulas: God is one in essence, and three in persons. Three modes of existing in God — but not three beings. These are not roles, functions, or moments in time: they are real persons, eternally distinct, yet indivisible. The Father is not the Son, and yet everything the Father is, the Son is also — fully, without diminution.
This co-belonging without confusion is utterly unprecedented. No other religious system has conceived it; no philosophy would have dared posit it. And yet, this is what the Gospel reveals: a God who speaks to himself, who sends and allows himself to be sent, who receives and gives — in a circulation of love without beginning or end.
1.2 – Alter-unity: Unity That Presupposes the Other
It is here that the concept of Alter-unity is born. Otherness without separation. Unity without fusion. In God, there is the Other — not in opposition, but within. The Son is the Other of the Father, and yet he is in him: "I and the Father are one" (John 10:30). The Spirit is the Other who proceeds from the eternal kiss of the Father and the Son — and yet he is neither secondary nor tertiary: he is co-eternal, co-divine, co-personal.
God, then, is the only Unity that does not cancel itself out in solitude. He is not the One of Parmenides, nor the indistinct Tao, nor the impersonal Being of modern pantheism. He is a Unity of Love, in which the Other is not absorbed, but affirmed.
This is what Alter-unity means: a unity that does not negate otherness, but founds it. A form of otherness that does not destroy unity, but fulfills it. It is the key to the Trinitarian mystery — and to all true relationships.
1.3 – Biblical, Philosophical, and Existential Coherence
Some have criticized Christianity for being too complex. But it is not the Trinity that is too complex — it is reality itself. And only a God in relationship is equal to the depth of reality.
Saint Thomas Aquinas, in his Summa contra Gentiles, shows that human reason can, without contradiction, recognize the existence of a unique God, source of all being, but that only Revelation could unveil that he is also relationship in himself1225-1274,_Thomas_Aquin….
This mystery surpasses reason, but does not contradict it. On the contrary, it sheds light on the most essential questions:
Why does God create? Because he is fullness, not lack.
Why does he love? Because he is already love in himself.
Why is relationship central to our lives? Because we are made in his image — and that image is not solitude, but communion.
Thus, the Trinity is not merely a dogma, but a source of rational light: it justifies creation, grounds love, and makes real relationship possible. Without it, God would be folded in upon himself. With it, God is gift from the beginning.
The Illusion of “All Is One”: A Critique of Monistic Spiritualities
In the face of the complexity of existence, inner wounds, and the world’s suffering, many seek refuge in spiritualities that promise peace through dissolution — the dissolution of the ego, the mind, the self, desire, and thought itself. All is One, they say — and that One is impersonal. One must simply “let go,” “awaken,” “merge.”
Against this alluring mirage, Christian faith dares another path: the path of saving otherness, not of absorption. The path of love rooted in distinction, not of peace bought by erasure.
2.1 – The Trap of Monistic Spiritualities
Religious monism teaches that there is only one Reality, and that all distinctions are illusions. Whether in ancient pantheism, contemporary neo-Vedanta, Western new age movements, or certain misread strands of Buddhism, the message remains the same: all is One. The other is merely a mask of the self. The self is but a reflection of the All. And God, if he exists, is that impersonal Totality.
But this seemingly peaceful idea contains a fundamental contradiction: it denies the possibility of true love. For to love, there must be an other. And if the other is only an extension of myself — or a mirage to be overcome — then love becomes an inflated narcissism. A caress of myself disguised as universal compassion.
And this caress of the self, far from being perceived as such, is often justified through a wide array of mental or meditative techniques, designed to produce an illusion of “non-duality,” of ego-dissolution, or mystical union with the All. But what it often is, in truth, is spiritual autosuggestion, where the self watches itself disappear, comments on its own vanishing, and rejoices in being “no one.” In reality, it is still there — more subtle, more elusive, yet always at the center, as the spectator of its own evaporation.
This proclaimed “absence of ego” makes no sense if it continues to observe, judge, and feel its own extinction. It is a performative contradiction: the one who says “I no longer exist” is still speaking, thinking, willing.
Christianity, by contrast, does not deny the self — it calls the self to die in love, which means for the sake of an Other, truly other than oneself.
Moreover, this pursuit of ego-dissolution amounts, in the end, to a reversed Pascalian wager: a reckless bet placed entirely on an inner experience declared absolute, while everything we know about the brain and its susceptibility to suggestion points to how easily such experiences can be induced — without any real contact with transcendence. From the standpoint of Occam’s razor, these states are easily explained by well-documented neuropsychological mechanisms: prolonged meditation, sensory deprivation, dissociation, auto-hypnosis.
And yet these experiences — however intense — are erected as ends in themselves, as “awakening,” as “realization.” Even though vocabulary differs from one tradition to another, it would be dishonest to deny that such states are proposed as spiritual goals, even if shrouded in poetic non-dual rhetoric. It is indeed a final state, an existential endpoint, founded not on relation, but on personal feeling: fragile, ambiguous, self-validating — not rooted in being, but in sensation.
In truth, to love everyone, in this framework, amounts to loving no one. For true love presupposes recognized, chosen, and received otherness. It presupposes the possibility of wounding, the acceptance of limit, the unique and personal yes. Christianity does not offer a mystical fog — it offers something far more beautiful, demanding, courageous — in short, more true: to love a person in their difference, not in spite of it, but because of it.
Unlike these nebulous spiritualities, the Trinity affirms that otherness is original, not illusory. In God himself, there is the Other — not as rupture, but as love. And it is this that makes possible a real, selfless, eternal love.Not a dilution, but a communion.
2.2 – The Rejection of Mind and Discernment
Many modern spiritual paths, shaped by a superficial appropriation of Eastern traditions, encourage a kind of sacred amnesia: the mind must be “transcended,” the intellect silenced, judgment abandoned. One must enter into a “pure silence,” relinquish all discernment, and merge with “divine energy.” Thought is seen as an obstacle, reason as a trap, truth as a form of violence.
But here again, Christianity resists the current. It dares to say that reason is a gift of God, not a barrier to him. Saint Thomas Aquinas affirms with crystalline clarity: the truth revealed by God never contradicts the truth naturally accessible to reason1225-1274,_Thomas_Aquin…. Human intelligence is made to seek, to articulate, to discern. Though it cannot encompass the divine mystery, it can receive its first rays, and those rays are already light.
John Paul II once wrote that faith and reason are the two wings on which the human spirit rises to the contemplation of truth. To amputate one is to cripple the other.
God does not ask for the annihilation of thought, but its transfiguration. He does not demand the rejection of our humanity, but its fulfillment. What many modern spiritualities call “awakening,” the Gospel calls resurrection.
And this resurrection does not bypass the mind — it passes through it. The disciple is not asked to become a sponge in the sea of the impersonal, but to become fully human, aware, discerning, capable of loving in truth.
The Christian is not called to forget, but to remember; not to dissolve, but to be lifted; not to escape, but to offer his mind, his body, and his will in a movement of love — toward an Other who knows, who sees, who calls.
2.3 – The Ravages of False Angelism (Even Within the Church)
This fascination with the renunciation of desire, of thought, of affectivity has not always come from outside. It has, at times, infiltrated certain currents within Christianity itself — those that sought to shape the faithful into premature angels, denying their corporeality, scorning passions, refusing fragility.
The spiritual history of the Church bears the scars of such deviations. Rigorist movements have tried to force holiness by extinguishing all that makes us human — and in doing so, they have shattered generations of souls. Others have tried to skip over reason, reducing faith to emotion, intuition, or mystical blur. But this is not the Gospel.
The Gospel does not despise any part of the human being.The Word became flesh — not vapor.He wept, ate, laughed, suffered. He loved.And his love was not a fusion, but a free gift to others who were free.
The Christian path is not an escape from humanity, but its redemption. It is not a rejection of limits, but a sanctification of the very conditions of our existence. The desire that stirs us, the thought that seeks, the emotion that trembles — all are not obstacles to God, but material for grace. What must die is not the human, but the ego that would make itself God.
Christianity does not call us to levitate above the world, but to descend into it with the light of love. Not to be without body or soul, but to offer both as instruments of mercy. Not to hover in serene disincarnation, but to walk — feet soiled with dust, heart pierced — in the footsteps of the Crucified.
This is what the saints have understood. They did not seek to escape the real, but to transfigure it from within. Their silence was not emptiness, but adoration. Their asceticism was not rejection of the flesh, but offering of the whole being to the Beloved.
A Path for the Whole Human: The Trinity and the Beauty of the Christian Way
Against the backdrop of mystical escapes and self-extinctions promised by many contemporary currents, the Christian faith offers an integral path. A path that dissolves nothing, but transfigures everything. It rejects neither the body, nor the mind, nor the ego — it calls them all into relationship. For at the origin of all things, there is not the impersonal silence of a formless All, but the call of the Father, the response of the Son, and the breath of the Spirit. At the beginning, and at the end, there is Love.
3.1 – Christianity: A Religion of the Person
The Trinity reveals that God is not solitude, nor energy, but a living being. And to love is not to lose oneself in a flow — it is to give oneself to another who is not oneself. What man seeks in every form of spirituality — peace, unity, light — Christianity offers, but without the lie of indistinction.
It offers it through a real, personal, embodied relationship. God loves each one for themselves. He does not love humanity as a generic totality, but each human being as a unique person, called by name. This is what Alter-unity makes possible: a unity grounded not in fusion, but in the communion of liberties.
3.2 – The Trinity: Source of All True Relationship
If God is love in himself, then love is not secondary in reality. It is not an evolutionary accident, nor a social construct, nor a psychological need. It is ontological. It is the very structure of being.
This is why creation itself becomes intelligible: God creates not out of lack, but out of overflowing. The Son is begotten, not made. The Spirit proceeds, but is not lesser. And humanity is invited to step into this divine dance.
The universe, then, is not an accident — but a scene set for relationship: the relationship God freely wishes to weave with his creatures.
To love, then, is no longer an invention of our psyche — it is a response to a love that comes first. Love is not an illusion. It is our highest calling.
3.3 – A Vision That Saves the Mind, the Heart, and the Body
The Trinity saves the whole human person. It crushes neither thought, nor desire, nor flesh. It receives them, illuminates them, orients them. The Christian path is demanding, but also profoundly human. It does not ask us to deny ourselves, but to step into a truth greater than ourselves. A truth that does not abolish what we are, but carries it to its fullness.
Christ does not come to erase our contradictions: he assumes them, passes through them, resurrects them. The Spirit does not quench our impulses: he purifies them. The Father does not want our absorption: he wants our free return to him.
Christian faith, then, does not propose a renunciation of reality, but an elevation of reality by grace. It does not call us to “escape the ego,” but to die to ourselves out of love — which is something altogether different.Not erasure, but offering.
To die to oneself, in the Christian sense, is not to negate what one is: it is to freely choose to no longer place the self at the center of everything. It is to refuse self-idolatry — not existence. It is an offering of the ego, not its annihilation.Not disappearance, but transfiguration.
The Christian logic is not one of extinction, but of Paschal passage: we are not emptied in order to vanish, but in order to receive back more than we gave. “Whoever loses their life for my sake will find it” (Matthew 10:39). It is not a question of merging with the ocean, but of returning home to the Father — upright, free, beloved.
Conclusion: Alter-unity, a Key to Truth for Our Time
In these times of spiritual confusion and aesthetic wandering, the doctrine of the Trinity may seem abstract, almost forgotten. And yet, it holds a response of breathtaking power to the thirst of our age: a response that honors the mystery of otherness, the beauty of love, and the dignity of the person.
The concept of Alter-unity, which I offer here as a contemporary attempt to articulate this mystery, seeks nothing more than to invite us to contemplate once again the living God as relationship — not as an anonymous force, nor an abstract principle.
It is not true that all worldviews are equal. And it is not arrogance to say that the Trinitarian God is more beautiful, more true, more human than the projections we invent to soothe ourselves. He is the Other whom we can love without losing ourselves. He is the One who makes love possible.
In the next article, I will explore what this changes in the way we love: why Christianity insists on personal, incarnate, singular love — and why loving everyone is not the same as loving each one.
“What you believe you possess in yourself alone, you possess only by giving it away.”
