The Bible is the inspired, fully inerrant, authoritative "Word of God." The Bible is referred to as the Word of God, meaning it can be considered a direct line of communication from the Almighty God, penned by the authors of the respective books. The meaning is what the authors meant by the words that they used.
Logos. The most usual Greek term for “word” in the NT: occasionally with other meanings (e.g., account, reason, motive); specifically in the prologue to the fourth Gospel (John 1:1, 14) and perhaps in other Johannine writings (1 John 1:1; Rev. 19:13) it is used of the Second Person of the Trinity. In ordinary Greek parlance it also means reason.
