I must admit that I have a different view of Mr Likoudis’ work, though I have not read that particular book. I have read many of his articles online, as well as “The Divine Primacy of the Bishop of Rome and Modern Eastern Orthodoxy.”
When I was just beginning my reevaluation of Catholic claims, I actually had trouble finding authors who were willing to discuss Eastern Orthodox objections head-on. I found Mr Likoudis’ style to be refreshingly forthright. He certainly makes his case in a forceful manner, but that’s not always a bad thing. His writings (along with others) forced me to really reconsider my thoughts on issues such as Papal primacy. I know that some find him insufficiently in tune with modern ecumenism, but then, I was once a firm anti-ecumenist.
