On this Second Sunday of Lent, Holy Mother Church places before us a striking contrast: the sober exhortation of St. Paul to the Thessalonians (1 Thess. 4:1–7) and the radiant mystery of the Transfiguration (Matt. 17:1–9). Yet these are not disparate themes. Rather, they reveal the same path—the ascent from moral purification to contemplative glory. Lent begins in penance, but it leads to light.
“This is the Will of God: Your Sanctification”
St. Paul speaks plainly: “For this is the will of God, your sanctification: that you should abstain from fornication… For God hath not called us unto uncleanness, but unto sanctification.”
The Apostle reminds the faithful that sanctity is not an abstract aspiration but a concrete obedience. The Christian life requires mastery over the passions, reverence for one’s body, and charity toward one’s neighbor. In a world saturated with sensual disorder, this admonition remains as urgent as ever.
St. John Chrysostom comments that Paul does not merely forbid impurity, but calls believers to possess their bodies “in sanctification and honor.” The body is not evil; it is destined for glory. Therefore, Chrysostom teaches, self-restraint is not repression but preparation for transfiguration.
St. Augustine, too, emphasizes that chastity is an ordering of love. Sin disorders the soul by turning it toward lower goods; grace restores order by directing it toward God. The discipline of Lent—fasting, custody of the senses, mortification—is thus medicinal. It clears the eye of the soul to behold divine light.
The Church reads this Epistle before presenting us with Mount Tabor. Why? Because purity precedes vision. “Blessed are the clean of heart,” says Our Lord, “for they shall see God” (Matt. 5:8).
The Ascent of Tabor
Six days after foretelling His Passion, Our Lord takes Peter, James, and John up a high mountain apart. There He is transfigured: His face shines as the sun, His garments become white as light. Moses and Elias appear, conversing with Him. The Father’s voice resounds from the cloud: “This is My beloved Son, in whom I am well pleased: hear ye Him.”
St. Leo the Great teaches that the Transfiguration was granted to strengthen the Apostles for the scandal of the Cross. Before they see Him disfigured in suffering, they are permitted to behold His hidden glory. The glory is not new; it is unveiled.
Origen sees in the mountain a symbol of spiritual ascent. One does not perceive Christ’s divinity while remaining in the valley of worldly distraction. The Lord leads chosen souls upward—through prayer, detachment, and trial—into clearer vision.
St. Gregory the Great remarks that the shining garments signify the Church, illumined by Christ’s glory. Thus, the mystery is not for Christ alone; it concerns His Mystical Body. What shines in the Head must one day shine in the members.
From Mortification to Illumination
The liturgical wisdom of the Church binds together St. Paul’s moral exhortation and St. Matthew’s vision of glory. The path to Tabor passes through Thessalonica. The call to sanctification is the first step of ascent.
The Fathers frequently describe the spiritual life in stages: purification, illumination, and union. Lent corresponds especially to purification. By restraining the passions and conforming our lives to God’s commandments, we are freed from the darkness that obscures divine light.
St. Athanasius writes that the Word became man so that we might become “partakers of the divine nature” (cf. 2 Pet. 1:4). The Transfiguration reveals the destiny of human flesh united to God. But this participation requires cooperation with grace. As St. Paul warns, to reject sanctification is to “despise not man, but God.”
Thus, the Church does not allow us to gaze upon Tabor sentimentally. She reminds us: the same Christ who shines like the sun commands purity, obedience, and sacrifice.
“Hear Ye Him”
The Father’s voice is the interpretive key to both readings: “Hear ye Him.”
To hear Christ is to obey His commandments, as St. Paul insists. To hear Christ is to follow Him up the mountain of prayer. To hear Christ is to accept both His Cross and His glory.
Peter, overwhelmed, wishes to remain on the mountain: “Lord, it is good for us to be here.” Yet the vision fades. They descend. Lent, too, is not an escape from reality but a preparation for fidelity in daily life. The glory glimpsed in contemplation must strengthen us for the valley of trial.
St. Bede the Venerable observes that after the heavenly voice, the disciples see “no one but Jesus only.” Moses and Elias vanish. The Law and the Prophets give way to Christ, their fulfillment. In the end, sanctity consists simply in cleaving to Him alone.
The Lenten Resolution
Dominica II in Quadragesima invites us to ask:
- Are we truly pursuing sanctification, or merely avoiding scandal?
- Are we ascending through prayer and mortification, or lingering below?
- Do we desire the glory of Christ enough to accept the discipline that prepares us for it?
Let us not separate Tabor from Calvary, nor glory from purity. The radiance of the Transfiguration is the promised end of those who heed St. Paul’s call.
In this holy season, may we embrace sanctification with renewed fervor. For the One who shines upon Tabor calls us not to uncleanness, but to light. And if we follow Him faithfully through Lent, we shall one day behold—not fleetingly, but eternally—the Face that shines as the sun.
