On this Lenten feria, the Church gathers our attention around a single, piercing truth: man must be washed, illumined, and made new—not by his own strength, but by the merciful hand of God. The liturgy of Feria Quarta infra Hebdomadam IV in Quadragesima sets before us three luminous texts—Ezechiel, Isaias, and the Gospel of the man born blind—each unveiling a different facet of the same divine work: purification, conversion, and illumination.
“I will sanctify My great name… and I will pour upon you clean water, and you shall be cleansed.” (Ezech. 36:23–25)
The prophet Ezechiel speaks not merely of moral reform, but of a supernatural re-creation. God does not ask Israel first to make itself clean; rather, He declares that He Himself will cleanse. This is the mystery of grace. As St. Cyril of Jerusalem teaches in his Catechetical Lectures, “Since man could not purify himself, the Lord prepared for him the laver of regeneration, that what water accomplishes outwardly, the Spirit may effect inwardly.”
The promise continues: “I will give you a new heart, and put a new spirit within you.” (Ezech. 36:26) The Fathers consistently interpret this as a prophecy of Holy Baptism. St. Augustine writes, “The old heart is taken away when sins are remitted; the new heart is given when charity is infused.” The Lenten journey, then, is not a mere polishing of the exterior life, but a return to the font—to that interior renewal which alone can restore man.
Isaias sharpens this call with prophetic urgency:
“Wash yourselves, be clean… remove the evil of your thoughts… learn to do well.” (Isa. 1:16–17)
Here, the cooperation of man enters. God offers cleansing, yet man must not resist. The prophet moves from purification to justice, from interior cleansing to outward righteousness. St. John Chrysostom comments that the Lord “does not demand costly sacrifices, but a change of life; not offerings of beasts, but the conversion of the soul.” The Lenten fast, therefore, is empty if it does not touch the heart—if it does not break sinful habits, reconcile enmities, and restore justice.
Yet the most vivid image is given in the Gospel: the man born blind.
“I was blind, and now I see.” (John 9:25)
This miracle is no mere act of compassion; it is a sacrament in figure. Christ anoints the man’s eyes with clay and sends him to wash in the pool of Siloe—which is interpreted, Sent. The Fathers delight in this detail. St. Cyril of Alexandria explains: “The clay signifies the Incarnation, the Word made flesh; the washing signifies Baptism; and the pool ‘Sent’ reveals that all grace flows from Him whom the Father has sent.”
The man obeys, washes, and returns seeing. But the deeper miracle unfolds gradually: from physical sight to spiritual vision. At first, he calls Christ “a man”; then “a prophet”; finally, he confesses, “Lord, I believe,” and worships Him (John 9:38). This progression mirrors the catechumen’s journey—and indeed, the journey of every soul in Lent.
In contrast stand the Pharisees, who, though seeing, remain blind. St. Augustine remarks with solemn irony: “They saw the light, but hated it; he did not see, yet believed in it.” Thus the true blindness is not of the eyes, but of the heart hardened by pride.
The commemoration of St. Cyril of Jerusalem deepens this theme. As a master of catechesis, he guided the newly baptized into the mysteries they had received. He reminds us that illumination (photismos) is not the end, but the beginning: “Having been deemed worthy of divine illumination, guard what you have received, lest the adversary despoil you.”
Taken together, these readings form a single Lenten exhortation:
- Let God cleanse you (Ezechiel).
- Do not resist His call to conversion (Isaias).
- Walk in the light you have received (John).
This is the rhythm of grace: washing, renewal, illumination.
As we advance toward Passiontide, the Church gently but firmly asks: Are we still blind? Have we truly allowed ourselves to be washed? Or do we, like the Pharisees, cling to the illusion of sight while refusing the light?
Let us then go to the pool of Siloe—Christ Himself. Let us submit to His cleansing, accept the new heart He offers, and confess with the healed man:
“Lord, I believe.”
And believing, may we see.
