Bible, Names of the
The Bible contains the revelation of God to man, and is therefore named from the Greek, biblion, "The Book," book of all books.
Our Lord used the name Scriptures (Latin: scribere, to write), in Matthew 22, because it is the written record of that revelation, the Written Word, or Holy Writ.
The Evangelists also use this name.
It is also known as the Old and New Testaments, Testament meaning the covenant, the understanding between God and man, the word Old designating revelation prior to the coming of Christ, and New, His own revelation as recorded by the Apostles.
Other names still are Holy or Sacred Book, Revelation, and Word of God.
