from The Century Dictionary.

• Hallowed, consecrated, or made holy by association with divinity or divine things, or by solemn religious ceremony or sanction; set apart, dedicated, or appropriated to holy or religious purposes or service; regarded as holy or under divine protection: as, a sacred place; a sacred day; sacred service; the sacred lotus.
• Devoted, dedicated, or consecrated with pious or filial intent: with to: as, a monument sacred to the memory of some one.
• Devoted to destruction or infamy; execrable; accursed; infamous.
• Of or pertaining to religion or divine things; relating to the service or will of the deity: opposed to secular and profane: as, sacred music; sacred history.
• Entitled to consideration, respect, or reverence; not to be thoughtlessly treated or intruded upon; venerable.
• Hence To be kept inviolate; not to be violated, profaned, or made common; inviolate.
• Not amenable to punishment; enjoying immunity: as, the king's person is sacred.
• Synonyms Sacred, Holy. Holy is stronger and more absolute than any word of cognate meaning. That which is sacred may derive its sanction from man; that which is holy has its sanctity directly from God or as connected with him. Hence we speak of the Holy Bible, and the sacred writings of the Hindus. He who is holy is absolutely or essentially free from sin; sacred is not a word of personal character. The opposite of holy is sinful or wicked; that of sacred is secular, profane, or common.
