Kyle,
I just noticed that the Whedon's commentary has two series designations. The new testament has "a popular commentary on the new testament" the old testament has "commentary on the old testament"

The I noticed that Philip Schaff has a 4 vol set with the same series name.

Shouldn't Whedon's series old and new have the same series designation? Whedons commentary on the old and new testaments.
