Thanks for the feedback - its is certainly helpful to gauge reaction, though it would be more productive and help foster more learning if there were quotes from other perhaps other respected publications on Orthodoxy.
I was hoping for feedback from some of those who might have read it, either the original French translation or the recently published English version, but there is still time.
I have not read the book myself, yet, but I do read a lot and it is on my list.
However I know New City Books, London, the publishers well. They specialise in Christian spirituality, fathers of the Church etc. and reject all but the finest books. I have many of their books, more recently 'Fasting
' by an excellent Greek (I think) scholar, Dag Tessore who specialised in biblical and patristic studies. He has written widely on a number of topics, including war and the spirituality of arms in Christianity and Islam. He explains the austere time-frames and dietary restrictions for fasting in the early church and similar practices still followed in the Orthodox churches. He lives in Greece.
Hope this is of some interest.
