Bloesch is weird. He is a Barthian, so these volumes will have the usual attacks on propositional revelation and inerrancy. Further, he is not altogether clear on election and soteriology. But on the same token, he accuses (rightly) synergistic models as being Pelagian and semi-Pelagian.
I would not recommend this to the beginning student. The advanced student will find some value if he reads carefully.
