I should probably further qualify my above comments on Grillmeier's work, since it may seem that I have been a bit unjust. Other positive qualities of the work include, as already noted, its unique comprehensiveness, and the fact he engages with a uniquely wide range of primary source material. It's not harshly polemical, and does seem to be a genuine attempt to do justice to the OO position in some respects, but ultimately, it remains something of a Chalcedonian apologetic (which is what one would expect of a RC theologian).
I should also sress that I was not seconding a recommendation of Fr. Samuel's book in opposition to Grillmeier's series. The former work, however, does have the luxury of having being composed well after Grillmeier's series and hence in consideration of it. As such, Fr. Samuel had and used the opportunity to address many of the shortcomings of Grillmeier's approach, reasonings and conclusions.
Finally, I must add that I have yet to read the entire series of Grillmeier's work. I have, as of now, only read Volumes 1 and 2A, as these are the only ones available to me.
