Saint

One separated from the world and consecrated to God; one holy by profession and by covenant; a believer in Christ (Ps 16:3; Rom 1:7; 8:27; Phil 1:1; Heb 6:10).

The “saints” spoken of in Jude 1:1:14 are probably not the disciples of Christ, but the “innumerable company of angels” (Heb 12:22; Ps 68:17), with reference to Deut 33:2.

This word is also used of the holy dead (Matt 27:52; Rev 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.
