The word in the Bible for
"saint" or "saints" is the word (hagios) also translated "sanctified" or
"holy ones." The root word hazo, means "to venerate." Hagios
means to be separated from sin
and therefore consecrated to God.
Hagios is used of God (Luke 1:49; Acts 3:14; Matthew 1:18,
It is a word used of men and
things (1 Timothy 1:9; 1 Peter 2:5,
9, etc.) When Paul uses the word "saint" in the singular, he refers to a state into which God calls men and women with His grace.
Philippians 4:21 Give my greetings to every holy one
(hagion) in Christ Jesus.
