Priestly Purity and the Holy Things (Part 2)
9“‘They shall therefore follow my commandment, lest they bear sin for it and die in it, if they profane it. I am Yahweh who sanctifies them.
Leviticus 22:9 commands Aaronic priests to meticulously observe regulations regarding ritual purity when handling sacred offerings, warning that profaning these holy things incurs guilt and death. The verse emphasizes that priestly holiness derives entirely from God's consecration, making careless or impure treatment of sacred items a grievous violation of divine trust.
Holiness is not something priests generate or own—it is God's gift that demands reverent custody, and carelessness with the sacred is not a minor infraction but a capital sin.
"I am Yahweh who sanctifies them." This divine self-declaration (ʾănî YHWH məqaddəšām) functions as both warrant and warning. It is theologically the most freighted clause of the verse. The sanctification of the priests is not achieved by the priests themselves; it flows entirely from Yahweh's initiative. This formula recurs throughout the Holiness Code (Lev 17–26) like a refrain — "I am Yahweh who sanctifies you" — undergirding every moral and ritual demand with the reminder that Israel's holiness participates in, and is derived from, God's own holiness. The priests are not holy by birthright or personal merit; they are holy because God has consecrated them. But precisely because their holiness is God's gift, misusing it is a uniquely grievous act — it is profaning what God Himself has made sacred.
Typological and Spiritual Senses In the typological reading so favored by the Fathers, the Aaronic priesthood prefigures the priesthood of the New Covenant, fulfilled in Christ (Heb 7–9) and extended, in a participatory way, through the ordained ministers of the Church. The warning to "keep the keeping" resounds forward into the New Testament's equally serious warnings about unworthy reception of the Eucharist (1 Cor 11:27–29). The theme of divine sanctification anticipates the explicit Johannine and Pauline theology of God as the source of all holiness in those He calls to serve Him (John 17:17–19; 1 Thess 5:23).
Catholic tradition reads Leviticus 22:9 on multiple levels, each illuminating something essential about the Church's own understanding of sacred ministry and the nature of holiness.
The Catechism and Priestly Holiness: The Catechism of the Catholic Church teaches that the ordained priest "acts in persona Christi Capitis" (CCC 1548) — in the person of Christ the Head. This understanding gives Leviticus 22:9 a stunning New Covenant intensification: the priest who handles Christ's Body and Blood in the Eucharist stands in an even more intimate — and therefore more demanding — relationship to the holy than Aaron's sons ever did. The warning against profaning holy things becomes, in this light, not merely disciplinary but theological: to approach the sacred ministry carelessly is to misrepresent Christ Himself.
The Church Fathers: St. Origen, in his Homilies on Leviticus, reads the Aaronic regulations as a mirror for the inner life of the Christian: bodily purity in the Torah becomes, spiritually, the purity of heart and conscience required of all who approach God. He writes that the priest's body symbolizes the soul, and the sacred food symbolizes the divine Word — "let no one, therefore, polluted by sins, dare to touch the Word of God." St. Cyril of Alexandria similarly stresses that the formula "I am the Lord who sanctifies" reveals that holiness is entirely participatory — no creature possesses it independently, but only by union with the Holy One.
The Council of Trent (Session 22) invoked the gravity of priestly unworthiness precisely in its teaching on the Mass, calling priests to the highest reverence in celebrating the Eucharistic sacrifice and warning of judgment for those who approach it with impure conscience.
Holiness as Relational Ontology: The concluding divine declaration — "I am Yahweh who sanctifies them" — encapsulates what Pope Benedict XVI described in The Spirit of the Liturgy as the logic of sacred worship: the initiative always belongs to God. Human beings do not generate holiness; they receive and guard it. This is why profanation is, at its core, a denial of dependence on God — a kind of practical atheism within the sacred sphere.
This verse speaks with quiet urgency to every Catholic who regularly approaches the sacraments — and especially to those in sacred ministry. The priest who prepares hastily for Mass, the deacon who handles the sacred vessels distractedly, the extraordinary minister of Communion who has lost a sense of awe — all are addressed by the spirit of Leviticus 22:9. But so is every lay Catholic who receives the Eucharist: the Church's long tradition of preparation, fasting, examination of conscience, and thanksgiving after Communion is not legalistic machinery but a living out of the priestly imperative to "keep the keeping."
More broadly, this verse challenges the contemporary tendency to collapse the distinction between the sacred and the ordinary. Catholic life is structured around sacred times, sacred places, sacred persons, and sacred things precisely because God's sanctifying action needs space to be honored and received. The remedy for routine and irreverence is not more effort but deeper attentiveness — returning to the question: Whose holiness am I handling? The answer, "I am Yahweh who sanctifies them," should re-enchant what familiarity has dulled.
Commentary
Leviticus 22:9 — Verse-by-Verse Commentary
"They shall therefore follow my commandment..." The Hebrew behind this phrase, וְשָׁמְרוּ אֶת-מִשְׁמַרְתִּי (wəšāmərû ʾet-mišmartî), is literally "they shall keep my keeping" — a doubled expression of vigilance that intensifies the obligation. The verb šāmar carries the sense of guarding, watching, and preserving. It is the same root used of Adam and Eve being placed "to keep" the garden (Gen 2:15), and it resounds throughout the Priestly and Deuteronomic literature as the characteristic posture of the covenant people before God. The pronoun "they" refers specifically to the Aaronic priests addressed in the surrounding passage (Lev 22:1–8), who have been instructed to maintain ritual cleanness before approaching the sacred donations (qodāšîm) of Israel. The commandment here is not abstract — it follows concrete regulations about bodily states (contact with corpses, skin disease, seminal emission, etc.) that rendered a priest temporarily unclean. The insistence on "following" or "keeping" the commandment points to habitual, attentive practice, not merely occasional compliance.
"...lest they bear sin for it and die in it..." The phrase "bear sin" (wənāśəʾû ḥēṭʾ) is a technical legal and cultic expression in Leviticus meaning to incur guilt and its penal consequence. It is closely related to the concept of bearing iniquity (nāśāʾ ʿāwōn), a burden that can, in the most severe cases, result in being "cut off" from the community (cf. Lev 7:20–21) or in death. Here, death is explicitly named as the consequence of profaning holy things, situating this verse within a pattern of capital-level offenses in Leviticus that cluster around the mishandling of the sacred — from unauthorized fire (Lev 10:1–2) to approaching the Holy of Holies improperly (Lev 16:2, 13). The gravity of the warning reflects the theological conviction that proximity to the holy is not morally neutral: it either sanctifies the reverent or destroys the careless. The sacred offerings represent Israel's living covenant relationship with God, and a priest who treats them contemptuously unravels the very fabric of mediation he is called to maintain.
"...if they profane it..." The verb ḥālal (to profane, defile, desecrate) is the antonym of qādaš (to make holy). To profane is to drag what belongs to the sphere of the sacred into the sphere of the common or unclean — an ontological transgression as much as a ritual one. In the context of the previous verses, profanation occurs when a priest eats from the holy offerings while in a state of ritual impurity. This is not mere ceremonial fastidiousness; the offerings have been consecrated to Yahweh, and to consume them improperly is to act as though God's claim on them — and on His servant — is negligible.
