Sacred means revered due to sanctity and is generally the state of being perceived by religious individuals as associated with divinity and considered worthy of spiritual respect or devotion; or inspiring awe or reverence among believers.
From an anthropological or atheistic perspective, the religious view of the sacred is an emic perspective on a culture's collection of thoughts and practices that function as a basis for the community's social structure.
Objects are often considered sacred if used for spiritual purposes, such as the worship or service of gods. The property is often ascribed to objects (a "sacred artifact" that is venerated and blessed), or places ("sacred ground").
The word "sacred" descends from the Latin , that is consecrated, or dedicated to the gods or anything in their power, and to sacerdos and sanctum, set apart.
Although there are similarities between the terms "sacred" and "holy" and they are sometimes used interchangeably, there are subtle differences. "Holiness" is generally the term used in relation to persons and relationship, while "sacredness" is used in relation to objects, places, or happenings. Thus a saint may be considered as holy, but he is not viewed as sacred. However, there are things that are both holy and sacred such as the holy bible.
The English word "holy" dates back to at least the 11th century with the Old English word hālig, an adjective derived from hāl meaning "whole" and used to mean "uninjured, sound, healthy, entire, complete". The Scottish hale ("health, happiness and wholeness") is the most complete modern form of this Old English root. The word "holy" in its modern form appears in Wycliffe's Bible of 1382. In non-specialist contexts, the term "holy" is used in a more general way, to refer to someone or something that is associated with a divine power, such as water used for baptism.
