I read the translation from the Holy Transfiguration Monastery in Boston. St. Maximus is great. No question there. Some of the discussion concerning the uncreated nature of grace (more specifically in episcopal consecration) and the abandonment thereof by hierarchs through heresy sheds light on the need to continually abide in the truth (2 Jn. 1:9).
However, I was disappointed at this particular version because it seems that they were more out to prove a point about the calendar. For example, the book is dedicated thus: "Dedicated to all the clergy, monastics, and laity who in this hemisphere have withdrawn from communion with those hierarchs and churches which have espoused the heresy of ecumenism, and who in this unbelieveing and perverse generation have stood fast in the Orthodox confession."
The subsequent 70 pages of this book are all painted with this self-justifying shade to the point that the dogma of Christ's two wills becomes more of a side note. Instead the theme of St. Maximus vs. the Empire becomes a desperate opportunity to rant about "the ecumenists."
It is not as if ecumenism isn't a problem, but I really wanted to learn more about the life of St. Maximus rather than the indignation of schismatics -_-
