What word or phrase does your mother always say?
early 14c., "the sacred writings of the Bible;" mid-14c., "a writing, an act of writing, written characters," from Late Latin scriptura "the writings contained in the Bible, a passage from the Bible," in classical Latin "a writing, character, inscription," from scriptus, past participle of scribere "write" (see script (n.)).
invariably in the New Testament denotes that definite collection of sacred books, regarded as given by inspiration of God, which we usually call the Old Testament (2 Tim. 3:15, 16; John 20:9; Gal. 3:22; 2 Pet. 1:20). It was God's purpose thus to perpetuate his revealed will. From time to time he raised up men to commit to writing in an infallible record the revelation he gave. The "Scripture," or collection of sacred writings, was thus enlarged from time to time as God saw necessary. We have now a completed "Scripture," consisting of the Old and New Testaments. The Old Testament canon in the time of our Lord was precisely the same as that which we now possess under that name. He placed the seal of his own authority on this collection of writings, as all equally given by inspiration (Matt. 5:17; 7:12; 22:40; Luke 16:29, 31). (See BIBLE ØT0000580; CANON.)
