My discussion of John 1:1-5 is up on Patheos.
A full version, with notes, can be found here:
I have basically shifted gears in my previous study of John 17. I decided that I had covered so many issues, and there were so many more to cover, that I would do a commentary on all of John, instead of just John 17. I'm going to cannibalize my earlier material from John 17 and put it in logical places in my full John commentary.
