Word Origin & History

The verb ἁγιάζω emerged from the rich theological soil of the Septuagint, where it translated the Hebrew קָדַשׁ (qadash). In classical Greek literature, though less common, it appeared in religious contexts describing the consecration of temples and sacred objects to the gods, as noted in Herodotus’s Histories.

The transition from classical to biblical usage expanded its meaning significantly, encompassing not just ritual consecration but the transformative work of making something or someone holy in character and purpose.

Biblical Usage

In the New Testament, ἁγιάζω appears 29 times, reflecting both instantaneous and progressive aspects of sanctification. It describes both God’s definitive act of setting believers apart and the ongoing process of spiritual transformation.

Key Passages:

• John 17:17 – “Sanctify them in the truth; Your word is truth.”
• 1 Thessalonians 5:23 – “Now may the God of peace Himself sanctify you completely”
• Hebrews 10:10 – “We have been sanctified through the offering of the body of Jesus Christ once for all”

Cultural Insights

In the ancient Mediterranean world, the concept of sanctification was deeply connected to temple worship and ritual purity. Objects, places, and people designated for divine service underwent specific purification rites. This cultural background illuminates why the early church understood sanctification as both a status change and an ongoing transformation.

Theological Significance

The doctrine of sanctification, rooted in ἁγιάζω, reveals God’s commitment to not only declare His people holy but to make them holy. This dual aspect reflects both His judicial declaration and His transformative power.

This word powerfully demonstrates the trinitarian nature of sanctification: the Father sanctions it, the Son secures it, and the Spirit applies it. It stands as a testament to God’s complete work in salvation, showing that He not only saves from sin’s penalty but also from its power.

Personal Application

Understanding ἁγιάζω challenges believers to view sanctification not as mere moral improvement but as a divine work of transformation. This perspective encourages us to cooperate with the Holy Spirit’s sanctifying work while remembering that God Himself is the source and power of our holiness.
