I would not be as interested in a leather edition if it meant the cost would be higher. It sounds like a very valuable endeavor but as one who already has and uses the FP version, if it were too expensive I probably couldn't justify getting another one. And of course, I welcome anything that helps me justify getting another book
My personal preference is to see
all the "traditional" documents included. Too often Presbyterians lose sight of what the Westminster Assembly was really doing. They wanted a uniformity of religion in doctrine, worship, government and discipline. Having all the documents emphasizes this, in my personal opinion. If Presbyterians today would like to see that same goal achieved, we should return to one of the best expressions of that desire in all the documents produced by the Assembly.
