"Enlarged" Scripture?

I have heard it hypothesized that there were 2,000 years in which God the Father was emphasized and then 2,000 years in which God the Son was emphasized and the next 2,000 years, God the Holy Spirit will be emphasized. So building on that speculation, maybe 1900 to 2000 could be called a Transition Time - a time in which we were transitioning from a Son Time to a Holy Spirit Time. After all, in the last 100 years, world wide, there were 3 major "moves" of a Holy Spirit type phenomena.

While we are speculating, the last time there was a shift in emphasis, there was an addition to the Scriptures. Wouldn't if be interesting if, in maybe 300 years, (if we could return) we would find that indeed, our Scriptures had been "enlarged"!
