What does 'saint' mean in the Bible?

Answer 1

In the New Testament the Greek word hagios (literally meaning 'Holy') is used of God's people and is translated as 'saints' meaning 'holy ones.' This really means to be 'set apart' and the holiness of the saints is then the conduct expected of those who are separated or set apart unto God.

"In the plural, as used of believers, it designates all such and is not appled to persons of exceptional holiness, or to those who, having died, were characterized by exceptional acts of "saintliness." See especially 2Thess. 1:10, where "His saints" are also described as "them that believed," i.e. the whole number of the redeemed."

10When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.

The word saint seems to agree in the Hebrew and Greek, so, in the Greek the root word is hagos, an awful thing, or a thing full of awe as the word awful was used in the original English intent. It means purified ceremonially, holy, consecrated.
