Second, the proper sphere of the holy in the NT is not priestly or ritual but the prophetic. The sacred no longer belongs to things, places, or rites, but to manifestations of life produced by the Spirit. In Paul’s letters those who name Jesus as their Lord are called hagoi, “saints.” This is not primarily an ethical expression but is parallel to being “called” (Rom. 1:7; 1 Cor. 1:2), “chosen” (Rom. 8:33; Col. 3:12), and “Faithful” (Col. 1:2). It implies association with the Holy Spirit. Christ is the one in whom believers become holy to the true God (see 1 Cor. 6:11). The power to do so comes from the risen Christ, who operates according to the Spirit of holiness (Rom. 1:4). In these cases holiness refers to a relationship with God that is not mediated through ritual (ceremonial) observance but through the leading of the Holy Spirit (Rom. 8:14). Spiritual worship is the offering of oneself as a living, holy sacrifice, acceptable to God (Rom. 12:1).[8]
This word is also used all over the LXX. This is the word used in the name the Holy Spirit; this is the word which is used of the “saints”; this is the word which is used of that which is separated for religious use. Louis Berkhof observes that hagios is “The really characteristic word of the New Testament” and ”Its primary meaning is that of separation in consecration and devotion to the service of God. With this, is connected the idea that what is set aside from the world for God, should also separate itself from the world’s defilement and share in God’s purity. This explains the fact that hagios speedily acquired an ethical signification.”
Next up is the noun ἁγιασμός (hagiasmos, G38). This word is used 10 times in the New Testament and it could basically be translated as “holiness” or “sanctification.” Mounce explains that hagiasmos '(“holiness, sanctification, consecration”) is generally used in the NT in the moral sense, referring to the process (or the final result of that process) of making pure or holy.”[8] So, Paul says that we should no longer present our bodily members as “slaves to impurity and to lawlessness”, but as “slaves to righteousness leading to sanctification” or holiness (Rom. 6:19). While we are now ahead of ourselves, here we see that sanctification does not merely affect us internally, but externally also in what we do with our bodily members for example. In Romans 6:22, we are set free from sin and the fruit from that “leads to sanctification and its end, eternal life.” 1 Corinthians 1:30 teaches that Christ has even become “sanctification” to us, which He does by His Holy Spirit, the Agent of sanctification. God’s will and calling are for our sanctification (1 Thess. 4:3, 7) and the purpose is that we “[may] know how to control [our] own body in holiness and honor” (1 Thess. 4:4). Our salvation was “through sanctification by the Spirit and belief in the truth” according to 2 Thessalonians 2:13. There is a kind or degree of holiness which we must possess “without which no one will see the Lord” (Heb. 12:14), which the Lord works in us through discipline (Heb. 12:10, a different word is used here than hagiasmos). According to 1 Peter 1:2, our election “according to the foreknowledge of God the Father” was “in the sanctification of the Spirit”. Then there is the use in 1 Timo...
