It doesn't really matter who formed the compilation of books in Scripture, in that not only in their formation, but in their reading and interretation, the Holy Spirit is still at work today as before in the heart of each believer, even in our Prayers to the Father, interceding with inexpressible groanings to the Father presenting our righteousness to Him in a fashion acceptable to Him, in areas of which we know nothing.
Consider the anthropology of man, in body, soul, and spirit. So much of our worldly perspective of Scripture is identifying an anthology of some 66 books in one binding as a Holy Document, yet what is more important is that the Word of God, or LOGOS, merely provides our thinking, our soul, with some of the same language used to express His thinking, so that the Holy Spirit might be free to make that soulish thinking effective in the growth and setting apart of not only our thinking, our soul, but also in our spirit.
It has been said there are three methods of perception. The senses, as in the body; Rationalism, as in logic/reason, or our soulish thinking; and spiritual perception.
Too often in a worldly sense, i.e. an attempt to bring order out of chaos, we attempt to limit Scripture to only a series of rationalistic expressions, yet His Word is much more than this. The Holy Spirit is able to take our thinking which is being transformed by His Word and further change our thinking, then our spirit, and manifest in our heart and what comes out of man.
In a sense, the only thing that amounts to (divine) good from man is based upon the activity of the Holy Spirit in us. Likewise, even if presented with a distorted form of the Scripture, if we still understand His meaning from that Scripture, He is still free to sanctify us.
