The Holy Bible
The Holy Scriptures, the writings of the Old and New Testaments, were composed under the inspiration of the Holy Spirit, and are accepted as canonical.
The Old Testament denotes the canonical texts which Christianity shares with Judaism, and which reveal God at work in creation, and among people and the events of history.
The New Testament denotes the canonical texts which relate exclusively to Christianity, and which set forth the life and teachings of Jesus Christ.
These texts are called the Word of God, because they were inspired by the Holy Spirit and because God speaks to us through them.
