The key words must be
2 Timothy 3:16-17
"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works."
In order for
all scripture to be so useful, all of it must be easily and uniformly understood by each reader without dissension among us, else it is not so profitable for those unable to understand it all. It is not given to us like two miss matched oxen unable to plow a straight furrow.That can't be due to confusion within the scriptures themselves since it is given by inspiration from God, and is perfect. I think the problem among many is a feeling the scriptures need to be interpreted again over and over, when it is sufficient to receive the translations into a language the reader can use. When existing translations were made the issue of transmission of meanings was settled before going to print. I find it easy to understand the more difficult passages upon matching them with other scriptures usually not many pages away, which requires much study of all the canonized scriptures. That becomes distorted when trying to mix in the apocrypha and other conflicting messages, doctrines of men, and stray traditions.
My opinion about 'three words of God' is there is only one Word of God which came by various means, that is, recorded spoken words (Gr. rhema) attributed to the three Godhead persons and those of mortal men; by record of acts of God (and men) such as the original inscription of Law on the stone tablets given to Moses, and other events witnessed by people; and by inspiration from God the Father and angels as in Daniel's experiences, the prophets, and contributions of the apostles by recall of what they saw and heard, amplified by the Holy Spirit, all recorded in letters (Gr. logos) by men. The textual scriptures are God's chosen manner of delivery of those records spoken and or inspired long ago. All the words from God, the recorded acts of God, and the eternal person of Jesus as revealed in the Bible constitute one Word of God.
An idea that supports that in me is the fact Jesus didn't take credit for anything He spoke or did (Jn 14:10), but spoke only what the Father said, and He did only what the Father did. When Jesus quoted scriptures as His teaching authority, by that same principle it was the Father God quoting His own word through Jesus. In other words Jesus didn't originate the words He delivered, like all true prophets of God per 2Peter 1:20-21. That's good enough for me to call all of holy scripture as represented in the Bible texts the one Word of God. That was embodied in Jesus such that because He totally lived by that word from Heaven he is called by God "The Word of God". One Word of God brought to us by several means, today entirely contained in the 66 books of the Bible.
Enjoying your discussion very much!
