As far as I am aware, neither Meyendorff nor his students ever rose to the challenge of responding to Romanides' rather devastating critique. Pelikan is diplomatic in his section on this, and doesn't come down on one side or the other -- perhaps because he didn't at the time understand how central Palamas's role is in summarizing the consensus patrum.
There has recently, BTW, been a wonderful book published by St. Tikhon's Seminary by their most first-rate professor there. It is a translation of many of St. Gregory Palamas's sermons for Sundays and feasts. One is struck by their simple directness, lack of ostentation, and brilliant summary of the paristic tradition.
Because we have so few of his writings available in English, we often don't appreciate just how central he was.
Which, of course, is all the more reason for you " xenoi" to learn the mother tongue! (Not you, Alex; you aleady know it better than I do!)
Pelikan sounds interesting. I will put him on my reading list, which is much too long already, as well as the other book you mention.
