(Isa. 49:7)
Christ is the Holy One, a designation signifying that he is a holy, pure, sanctified Person, One who was and is without sin, who had no need for repentance, and who stands perfect in all things… . (Isa. 43:15; 49:7; Ps. 16:10; Acts 2:27; 3:14; 13:35; 2 Ne. 9:20, 41; 3 Ne. 26:5; Morm. 9:5, 14; D&C 78:16.) … (Isa. 6:3). “Holiness unto the Lord” will be emblazoned on useful items of every sort in that millennial day when the Holy One reigns personally upon the earth (Zech. 14:20–21).
