If anything, I would say that the writings of Cardinal Ratzinger/Pope Benedict XVI are MUCH more readable and down-to-earth than those of John Paul II. I flatter myself that I can read fairly well, yet I often had to really *slog* through the writings of JPII, going over the same sections several times to make sure of the sense.
This is hardly a problem with BXVI. His writings in German are crystal clear, and lend themselves well to English translations that are conprehensible to most reasonably versed laymen. He could stand a little more "popularization" in his writings for the laity, but I'll be thankful for the current clarity even if it doesn't move an inch closer to us among the Unwashed! ;-)
JP 2 was a philosopher. I think their job is to not write lucidly! Have you ever read Kant? Whew!
Yes, John Paul can be difficult to read, but it is worth the effort. Actually, there is one I found very good, reading-wise, and that is Veritatis Splendor. I have bought a book that goes through all of his encyclicals in "English" for simpletons like myself. I am not home now, so I don't remember the title. If you want it, private mail me and I'll get you the title. There are also books like this on the Vatican 2 documents. It makes reading them (and John Paul 2) much easier.
I also find Benedict's writings to be more clear.
