The written record of God’s revelation is the Bible, which means the book, or the books. The Bible is also called the Holy Scriptures. Scripture as a word simply means writings.
The Bible was written over thousands of years by many different people. It is divided into two testaments or covenants. These words signify agreements, pacts, or we might say, ‘deals.’ The two basic covenants are the old and the new; each has its own scriptures. As a book, the Bible contains many different kinds of writings: law, prophecy, history, poetry, stories, aphorisms, prayers, letters and symbolical visions.
The Old Testament
The Old Testament scripture begins with the five books of the Law called the Pentateuch, which means the five books; also called the Torah, which means the Law. Sometimes these books are also called the Books of Moses since they are centered on the exodus and the Mosaic laws.
In the Old Testament there are also books of the history of Israel; books called the Wisdom books such as the Psalms, Proverbs, and the Book of Job; and books of the prophecies which carry the names of the Old Testament prophets. A prophet is one who speaks the Word of God by direct divine inspiration. Only secondarily does the word prophet mean one who foretells the future.
The Orthodox Church also numbers among the genuine books of the Old Testament the so-called apocryphal books, meaning literally the secret or hidden writings. Other Christians put these books in a secondary place or reject completely their being of divine inspiration.
The New Testament
The center of the New Testament part of the Bible is the four gospels of Matthew, Mark, Luke, and John, who are called the four evangelists, which means those who wrote the gospels. Gospel in Greek is evangelion which means the “glad tidings” or the “good news.”
In the New Testament scripture there is also the book of the Acts of the Apostles, written by Saint Luke. There are fourteen letters called the epistles (which simply means letters) of the Apostle Paul, though perhaps some, such as the Letter to the Hebrews, were not written directly by him. Three letters are also ascribed to the apostle John; two to the apostle Peter; and one each to the apostles James and Jude. Finally there is the Book of Revelation, also called the Apocalypse, which is ascribed to Saint John as well.
For the Orthodox, the Bible is the main written source of divine doctrine since God Himself inspired its writing by His Holy Spirit (see 2 Tim 3.16 and 2 Pet 1.20). This is the doctrine of the inspiration of the Bible, namely that men inspired by God wrote the words which are truly their own human words—all words are human!—but which nevertheless may be called all together the Word of God. Thus, the Bible is the Word of God in written form because it contains not merely the thoughts and experiences of men, but the very self-revelation of God.
The center of the Bible as the written Word of God in human form is the person of the Living Word of God in human form, Jesus Christ. All parts of the Bible are interpreted in the Orthodox Church in the light of Christ since everything in the Bible leads up to Christ and speaks about Him (Lk 24.44). This fact is symbolized in the Orthodox Church by the fact that only the book of the four gospels is enthroned on the altars of our churches and not the entire Bible. This is so because everything in the Bible is fulfilled in Christ.
