This is terrific. The translations are a little dry, but there is so much here at so low a price that it hardly weighs in on the matter. Want to know what Christianity has always believed? Read these. Want to know what the Early Church thought on something? Read it. In short, rather than read about what the Early Church thought on something, read the things they wrote. For that reason, this volume is indespensable to any Christian commited to learning about his faith.
I've searched all over the web for this set at a reasonable price and was able to get it here for $350, which comes out to less than $10 per volume. It's a steal for a brand new set. And I've already found it useful for a paper I was writing. While individually there are better translations out there of some of the authors in the set, the sheer comprehensiveness of this makes it a great investment.
