When Moses encounters God at the burning bush, he asks a question that has echoed throughout human history: “What is your name?” (Exodus 3:13). God answers with words as mysterious as they are profound: ʾehyeh ʾăšer ʾehyeh, traditionally rendered “I am who I am” (Exodus 3:14). The Greek Septuagint translates the phrase as egō eimi ho ōn, “I am the One Who Is.” This rendering has shaped Orthodox theology and iconography so deeply that the letters Ho Ōn, “The One Who Is”—appear in the halo of Christ. Yet the revelation of the divine Name is not exhausted by any single translation.
The Hebrew invites us to hear another dimension. The form ʾehyeh, from the verb hāyāh, “to be,” can be understood not only as “I am” but also as “I will be.” Biblical Hebrew does not map neatly onto the tense system of English; its verbal forms can convey an action that is incomplete or unfolding. Only a few verses earlier, God promises Moses, ʾehyeh ʿimmāk: “I will be with you” (Exodus 3:12). This earlier promise casts light on the revelation that follows. The Name is more than a statement about divine existence. It is also the assurance of a presence that will accompany Moses into a future he cannot yet imagine.
Notice the setting. Moses is not seeking a philosophical definition of the divine essence. He is a shepherd in the wilderness, startled by a bush that burns without being consumed. The God who calls him has already declared that he has seen the affliction of Israel, heard its cry, and known its suffering. God reveals himself in the midst of human distress and in anticipation of deliverance. The Name is spoken not in isolation from history but at the beginning of a journey. Moses will come to know the God who speaks by following the God who acts.
This brings us to what I would call the “unfinished Name” of God. In the literary context of Exodus, YHWH (conventionally pronounce Yahweh) is associated with the Hebrew verb “to be,” even though the precise etymology of the sacred Name remains debated. We may hear its theological resonance in the suggestive beginning of a sentence: “He is…” or “He will be…” But what follows? Where is the predicate? The question is not meant to suggest that God is incomplete. Rather, it reminds us that God’s self-disclosure is inexhaustible. The divine Name can be invoked in prayer, but the living God cannot be contained within a human definition or possessed by those who pronounce it.
The Fathers of the Church help us approach this paradox with reverence. In his Life of Moses, St. Gregory of Nyssa presents Moses’ journey as an image of the soul’s unending ascent toward God. Even when Moses draws nearer to God, the divine mystery is never reduced to something fully grasped. Gregory’s account of Moses entering the divine darkness suggests that authentic knowledge of God includes recognition of what surpasses knowledge. The closer one comes to the living God, the more one discovers that God exceeds every concept. This patristic insight does not cancel the revelation of the Name; it guards its depth. God truly makes himself known, yet never ceases to be infinitely greater than our knowing.
A related intuition appears in the writings of St. Dionysius the Areopagite, who insists that God transcends the names and affirmations by which we speak truthfully of him. We call God good, living, wise, and merciful because his gifts make these names meaningful to us. Yet no one of them, nor all of them together, exhausts the divine mystery. Thus the “unfinished Name” can be read alongside the Church’s apophatic tradition: revelation is genuine, but it is not possession; speech about God is necessary, but it must remain humble before the One who exceeds speech.
Israel learns who YHWH is through the unfolding history of divine faithfulness: deliverance from Egypt, passage through the sea, the gift of manna, the covenant at Sinai, and the long journey through wilderness, exile, and return. In a similar way, the faithful discover the meaning of God’s presence in the changing seasons of life. For the orphan, God is Father; for the widow, Protector; for the sick, Healer; for the frightened, Refuge; for the sinner, Mercy; for the lost, the Way Home; and for the dying, Life. These are not different gods fashioned by our needs. They are predicates and glimpses of the inexhaustible fullness of the one God, who meets human beings in their concrete circumstances without being confined by those circumstances.
There is also a pastoral lesson here. When suffering comes, we want explanations. We ask why God permits illness, grief, injustice, or silence. We may even feel obliged to complete the sentence on God’s behalf, as though a quick answer could make another person’s pain bearable. Yet God does not answer every question by offering a theory. When Moses asks, “Who am I that I should go to Pharaoh?” God does not list Moses’ qualifications or promise an easy mission. He answers, “I will be with you.” Moses asks about his own adequacy; God responds with the assurance of divine presence and companionship.
This promise can reshape the way we accompany one another. There are moments when the most faithful pastoral response is neither an explanation nor an attempt to make suffering appear good. It is to remain beside a person who suffers, refusing both despair and easy consolation. The unfinished Name invites us to leave room for what God may yet disclose. It teaches us to recognize the holiness of questions we cannot resolve and to trust that divine presence is not limited by the narrow horizon of what we presently understand.
Our own stories, too, remain unfinished. We may be tempted to define ourselves by failure, disappointment, or a season of spiritual dryness. We may pronounce final judgments upon a parish, a neighbor, or even our own vocation. But the God who says “I will be with you” is still at work. Moses could not foresee the sea opening before Israel while he stood before the burning bush. He had only a call and a promise. We should be careful not to place a period where God may have placed an ellipsis.
For Christians, the promise of divine presence finds its fullest expression in Jesus Christ, Emmanuel—“God with us.” The Gospel of John gives the words “I am” a distinctive resonance, as Christ speaks of himself as the bread of life, the light of the world, and the good shepherd. The One whom no name can contain enters human history and shares our life. The mystery is not abolished; it becomes astonishingly near. In Christ, the God whose Name remains inexhaustible is encountered not as an abstract possibility but as the living Lord who calls us into communion.
The unfinished Name, then, is not an absence to be feared but an invitation to faithfulness. We do not finish God’s Name by solving the mystery of his being. We learn to recognize his presence as we walk, pray, suffer, serve, and hope. The promise spoken to Moses still addresses the Church and each of us: ʾehyeh ʿimmāk—“I will be with you.” Sometimes that is enough to take the next step.
