The Gospel According to Mark commentary, written by Morna Hooker, and part of the
Black's Commentary series, is currently
free at Logos, in conjunction with
Logos' Christmas Sale.
This book is offered in addition to
the free book in Logos' regular monthly sale, which this month features a commentary on Exodus.
Looking at the composite of ratings of the Markan commentary at
GoodReads,
Amazon, and
Logos, I see that the ones for this book are truly stratospheric!
Best Commentaries ranks it "only" 14th of all commentaries; however, there is such a plethora of commentaries on this New Testament book that any ranking in the top 20 or 30 at
Best Commentaries should be considered awesome, IMHO.
The paperback at Amazon is $58. So, this is an outstanding
gift from the folks at Logos/Verbum!
The book runs only on the Logos/Verbum platform, but if you don't have it, not to fear. Logos/Verbum
gives away a rudimentary version of its software that will open this book.
