The Greek word hagios

Related to the Greek verb “hagiazo” (sanctify, purify) and the Greek noun “hagiasmos” (sanctification), the Greek word  “hagios” is an adjective.  This word means “holy” when applied to things and “consecrated” when applied to people.

This is a common New Testament word and in several places such as Mk. 12:36; 13:11 it describes the “Holy” Spirit.  This term is found in every New Testament book but Galatians, James, Second and Third John.
