The first three pages of the PCA Book of Church Order are simply indispensable. They disabuse us of the notion (relying on the Westminster Confession) that church government is optional, infinitely variable, or unimportant. We mentioned the Preface on this show.
Much of the Preface was based on versions of the PCUS Book of Church Order. The 1933 version may be accessed here.
your writing is valuable but the subscription is very high. I can get paper magazines delivered to my door with all the postal overhead for less. I have to believe that you would get far more subscribers and more gross revenue ( not to mention a broader reach). I'm retired and while I could afford this now the present environment makes me much more conservative with my funds.
