One separated from the world and consecrated to God; one holy by profession and by covenant; a believer in Christ (Psalm 16:3; Romans 1:7; 8:27; Philippians 1:1; Hebrews 6:10).

The "saints" spoken of in Jude 1:14 are probably not the disciples of Christ, but the "innumerable company of angels" (Hebrews 12:22; Psalm 68:17), with reference to Deuteronomy 33:2.

This word is also used of the holy dead (Matthew 27:52; Revelation 18:24). It was not used as a distinctive title of the apostles and evangelists and of a "spiritual nobility" till the fourth century. In that sense it is not a scriptural title.
