Much has been written about St. Gregory Palamas, and I, certainly, am not qualified to write about the saint or even comment on those writings. I do know that St. Gregory Palamas was greatly misunderstood during his life. I shall allow others to do my speaking for me on this.
First, there are the writings of St. Gregory Palamas himself (only 3 are included here – there are many more):
Gregory Palamas: The Saving Work of Christ
Next, there are commentaries about St. Gregory, of which six are included below:
Fr. Richard Demetrius Andrews: St. Gregory Palamas and the Prayer of Silence
St. Gregory Palamas on Icons as Tools for the Heart (Podcast from Ancient Faith Radio) [Link opens the podcast; Length: 16:01]
Fr. Bassam A. Nassif: Light for the World: the Life of St. Gregory Palamas (1296–1359)
Sergei V. Bulgakov: St. Gregory Palamas and the Second Sunday of Great Lent [on Mystagogy]
Second Sunday in Lent: St. Gregory Palamas
Although there are many more good references, this is all I will include here for now.
