HOLINESS

Chief attribute of God and a quality to be developed in his people. “Holiness” and the adjective “holy” occur more than 900 times in the Bible. The primary OT word for holiness means “to cut” or “to separate.” Fundamentally, holiness is a cutting off or separation from what is unclean and a consecration to what is pure.

In the OT, holiness as applied to God signifies his transcendence over creation and the moral perfection of his character. God is holy in that he is utterly distinct from his creation and exercises sovereign majesty and power over it. His holiness is especially prominent in the Psalms (47:8) and the Prophets (Ez 39:7), where “holiness” emerges as a synonym for Israel’s God. Thus, Scripture ascribes to God the title “Holy” (Is 57:15), “Holy One” (Jb 6:10; Is 43:15), and “Holy One of Israel” (Ps 89:18; Is 60:14; Jer 50:29).

In the OT God’s holiness denotes that the Lord is separate from all that is evil and defiled (cf. Jb 34:10). His holy character is the standard of absolute moral perfection (Is 5:16). God’s holiness—his transcendent majesty and the purity of his character—are skillfully balanced in Psalm 99. Verses 1 through 3 portray God’s distance from the finite and earthbound, whereas verses 4 and 5 emphasize his separation from sin and evil.

In the OT God demanded holiness in the lives of his people. Through Moses, God said to the congregation of Israel, “You shall be holy; for I the Lord your God am holy” (Lv 19:2, rsv). The holiness enjoined by the OT was twofold: (1) external, or ceremonial; and (2) internal, or moral and spiritual. OT ceremonial holiness, prescribed in the Pentateuch (the first five books of the OT) included ritual consecration to God’s service. Thus priests and Levites were sanctified by a complex process of ritual consecration (Ex 29), as were the Hebrew Nazirites, which means “separated ones” (Nm 6:1-21). Prophets like Elisha (2 Kgs 4:9) and Jeremiah (Jer 1:5) were also sanctified for a special prophetic ministry in Israel.

But the OT also draws attention to the inner, moral, and spiritual aspects of holiness. Men and women, created in the image of God, are called to cultivate the holiness of God’s own character in their lives (Lv 19:2; Nm 15:40). In the NT the ceremonial holiness prominent in the Pentateuch recedes to the background. Whereas much of Judaism in Jesus’ time sought a ceremonial holiness by works (Mk 7:1-5), the NT stresses the ethical rather than the formal dimension of holiness (vv 6-12). With the coming of the Holy Spirit, the early church perceived that holiness of life was a profound internal reality that should govern an individual’s thought and attitudes in relation to persons and objects in the external world.

The NT Greek equivalent of the common Hebrew word for holiness signifies an inner state of freedom from moral fault and a relative harmony with the moral perfection of God. The word “godlikeness” or “godliness” captures the sense of the primary Greek word for holiness. Another Greek word approximates the dominant OT concept of holiness as external separation from the profane and dedication to the service of the Lord.

Because the NT writers assumed the OT portrait of deity, holiness is ascribed to God in relatively few apostolic texts. Jesus affirmed the ethical nature of God when he enjoined his disciples to pray that the Father’s name might be esteemed for what it is: “Hallowed be thy name” (Mt 6:9, KJB). In the book of Revelation the Father’s moral perfection is extolled with the threefold ascription of holiness borrowed from Isaiah: “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come” (Rv 4:8, rsv; cf. Is 6:3). Luke, however, contemplated God’s holiness in terms of the dominant OT concept of his transcendence and majesty (Lk 1:49).

Similarly the holiness of Jesus Christ is asserted in the NT. Luke (Lk 1:35; 4:34), Peter (Acts 3:14; 4:27-30), the writer of Hebrews (Heb 7:26), and John (Rv 3:7) ascribe holiness to both the Father and the Son.

Since the Spirit comes from God, discloses his holy character, and is the instrument of God’s holy purposes in the world, he also is absolutely holy (Mt 1:18; 3:16; 28:19; Lk 1:15; 4:14). The common title “Holy Spirit” underscores the ethical perfection of the third person of the Godhead (Jn 3:5-8; 14:16-17, 26).

In the NT, holiness also characterizes Christ’s church. The apostle Paul taught that Christ loved the church and died for it “that he might sanctify her, having cleansed her by the washing of water with the word” (Eph 5:26, rsv). Peter addressed the church as a holy people in language borrowed from the OT. Separated from the unbelieving nations and consecrated to the Lord, the church is “a holy nation” (1 Pt 2:9; cf. Ex 19:6).

But the NT more often discusses holiness in relation to individual Christians. Believers in Christ are frequently designated as “saints,” literally meaning “holy ones,” since through faith God justifies sinners, pronouncing them “holy” in his sight. A justified sinner is by no means morally perfect, but God does declare believers to be guiltless. Thus, although Christians at Corinth, for example, were plagued with numerous sins, Paul could address his erring friends as those who were “sanctified in Christ Jesus, called to be saints” (1 Cor 1:2, rsv). Despite their problems, the Corinthian believers were “holy ones” in Christ.

The NT, however, places great stress upon the reality of practical holiness in the Christian’s daily experience. The God who freely declares a person righteous through faith in Christ commands that the believer progress in holiness of life. In God’s plan, a growth in holiness should accompany believing. God graciously provides the spiritual resources to enable Christians to be “partakers of the divine nature” (2 Pt 1:4).
