Saint

one separated from the world and consecrated to God; one holy by profession and by covenant; a believer in Christ ( Psalms 16:3 ; Romans 1:7 ; 8:27 ; Phil 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 ; Psalms 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.
