‘The new book by the Metropolitan John Zizioulas offers a passionate and extremely accessible study on the meaning of the Holy Communion: its biblical foundations and its role in manifesting the Kingdom of Heaven. Few works have been able to underline so emphatically the importance of the Eucharist in understanding the Church, and of its mysterious nature and its dynamic relationship with the world. In its development of the cosmic dimension of the Eucharist, this book seems to be very current. It shows that the Eucharist implies a veritable ethos in how we relate to the environment, man being not a master, but on the contrary a "priest", called to offer reverently to God all of creation. In the context of the major ecological crisis bearing down upon the world today, this book makes a decisive contribution to Christians and beyond.' - M. Michel Stavrou, Institut de Théologie Orthodoxe Saint-Serge, France.
