The Altar You Build Where the Cross Already Stands

Heart-Leaving and Heart-Finding — A Reflection for Fourth Week of Great Lent (Week of the Cross) on Isaiah 29:13-23 and Genesis 12:1-7

Midway through the Fast, the Church plants the Cross like a tree in the center of the road and says: now walk toward it. If any man will come after me, let him deny himself, and take up his cross, and follow me (Mark 8:34). And in that shadow—that strange, life-giving shade—she sets before you two readings that speak one word between them: leave what you know with your lips and go where you will know with your heart.

Isaiah names the sickness first. This people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me. Feel the cut of that. Not godlessness. Not rebellion. Nearness without presence. Worship that never descends below the throat. You have known this. You know it still—the prayers said while the mind drifts, the fasting that feeds the ego, the piety that performs for an audience of one’s own self-regard. Isaiah is not describing ancient Israel alone. He is describing the perennial temptation of every soul that has tasted God and then built a system to manage the taste. The Second Temple instinct lives in us all: replace encounter with regulation, substitute the precept of men for the terrifying intimacy of the living God. The stoicheia—those elemental structures of separation—do not only belong to the old dispensation. They reconstruct themselves in every generation, in every heart that prefers the predictable to the holy.

And God’s answer is not punishment. It is something far more destabilizing: I will proceed to do a marvellous work among this people, even a marvellous work and a wonder. The wisdom of the wise shall perish. The understanding of the prudent shall be hid. This is the Cross foreshadowed—the great overturning where strength works through weakness, where the foolishness of God undoes every competent arrangement we have made to keep ourselves safe from transformation. God does not correct your false worship by improving your technique. He shatters the frame. Maximos the Confessor understood this shattering as the necessary collapse of the gnomic will’s self-constructed world: “The one who has succeeded in attaining virtue and has enriched himself with spiritual knowledge sees things clearly in their true nature, and consequently both acts and speaks with regard to all things in a manner consistent with right reason” (Centuries on Love, I.93). But that clear sight costs everything you thought you knew.

Which is precisely where Abram enters. Get thee out of thy country, and from thy kindred, and from thy father’s house, unto a land that I will shew thee. Three severances. Country: the broad belonging, the cultural air you breathe without thinking. Kindred: the closer circle, the inherited patterns, the family wound passed down like heirlooms nobody asked for. Father’s house: the deepest root, the foundational story you tell yourself about who you are and why. God asks Abram to leave all three—not because they are evil, but because they have become the boundaries of the known. And the known, when it becomes a prison, wears the face of home.

Here is the Cross refracted through Genesis. To take up your cross is not first to suffer. It is first to leave. To walk away from the self you have built—the competent, coping, lip-honouring self—and go toward a land you cannot yet see. Gregory of Nyssa called this the epektasis, the perpetual stretching forward: “The one who ascends never stops, going from beginning to beginning, by beginnings that never end” (Homilies on the Song of Songs, 8). Abram at seventy-five is not young. His departure is not youthful adventure. It is the old, settled soul’s terrifying consent to become new.

What in you is the father’s house you have not yet left? What wound have you furnished and made habitable? What false self have you decorated with prayer and called holy? The Fast strips these rooms bare. The Cross stands at the threshold and says: there is a land beyond this. I will show it to you. But you must walk.

And then—this is the miracle Isaiah foretold—the deaf hear, the blind see out of obscurity and out of darkness, the meek increase their joy. The overturning is not destruction. It is Lebanon becoming fruitful field, wilderness becoming forest. The terrible one brought to nought. The scorner consumed. All that watched for iniquity—every voice in your skull that counts your failures—cut off. Irenaeus saw this convergence of promise and departure as the single movement of divine pedagogy: “God made man a free agent from the beginning, possessing his own power, even as he does his own soul, to obey the behests of God voluntarily, and not by compulsion of God” (Against Heresies, IV.37.1). The marvellous work is freedom restored—not imposed from without but uncovered from within.

Abram arrives in Canaan. The Canaanite is in the land. The promise is given amid the occupied, the contested, the not-yet-redeemed. And there builded he an altar unto the Lord, who appeared unto him. Not in a temple. Not behind a veil. In open country, among strangers, on ground that is not yet his. This is First Temple faith before there was a Temple—the primordial priesthood of encounter, of Melchizedek’s bread and wine, of the altar built wherever God appears. And it is the faith the Cross restores: not worship managed by precepts of men, but the raw, wind-struck altar of a heart that has finally left home and found the Holy.

Basil the Great wrote: “The Holy Spirit raises our hearts from earth, guides the steps of the weak, and brings to perfection those who are making progress” (On the Holy Spirit, IX.23). You are midway through the Fast. The Cross stands in the road. You have been walking. You are weary. Good. The weariness means you have actually been moving. Now look: the land is becoming fruitful before your eyes. The deaf places in you are beginning to hear. The blind places are straining toward light. Do not turn back to the father’s house. Build your altar here—in the contested, occupied, not-yet-redeemed territory of your own becoming. The God who appeared to Abram appears to you. The marvellous work is underway.
