I've posted a long discussion/review of Bordeianu here: http://easternchristianbooks.blogspot.com/2011/10/on-dumitru-staniloaes-ecclesiology.html

In particular, Bordeianu argues that the East might be aided by the West in two areas: its understanding of sacraments (including their very number, and their differentiation from "sacramentals"); and a fuller understanding of apophaticism in contemporary Trinitarian theology. In his discussion of sacraments and East-West relations, Bordeianu makes two incautious and inaccurate generalizations when he says that "any baptized Christian can be received in the Orthodox Church through Chrismation without needing a second baptism" and "the Orthodox Church recognizes some of the ordinations of other denominations"(39). In fact, there is no consistent practice for the reception into Orthodoxy of other Christians--as John Erickson showed a number of years ago in an article in St. Vladimir's Theological Quarterly. I know of several cases in which other Christians, including Roman Catholics, have been re-baptized, re-chrismated, and even, in the case of one Roman Catholic priest received into the Russian Church only this year, re-ordained! Many, but not all, Orthodox churches would not commit such sacrilege, but some do--including some Copts whom I know. There is, in fact, no consistency on these questions even within the same Orthodox Church, as recent and contrary examples in the Russian Church alone illustrate. (None of this is surprising, it should be noted: as the late Archpriest Robert Anderson always said to me, "in the East, everything is local custom.")
