I recently bought the 8 volume Socio-Rhetorical commentary bundle...realising that I would still have to purchase Craig S. Keener's new addition to the series on Matthew. BUT...lo and behold, I see that there are more volumes being released, but only as a part of the IVP New Testament Studies bundle. Why should I have to buy this whole bundle just to keep up with the Socio-Rhetorical commentary seires? And is the volume on Hebrews, James and Jude repeating the same commentary on Hebrews contained in "Perseverance in Gratitude"?
