Among the major Christian denominations, the Orthodox Church is the least known and widely misunderstood. This is more serious in Asia where the Orthodox Church is a minority and is perceived as an exotic branch of Christianity. But in fact, the Eastern Church has been in China since the seventeenth century. The purpose of this work is to acquaint lay people, theological students and seminarians with the teaching of Orthodoxy through a study of important modern Orthodox theologians. Mong argues that in spite of the differences and painful clashes between the Eastern and Western Churches, there is a lot that they share in common. Key topics like ecclesiology, ecumenism, catholicity, traditions and liberation theology are explored in the works of Jaroslav Pelikan, Nicolas Berdyaev, Nicolas Afanasiev, Georges Florovsky, Sergei Bulgakov, John Meyendorff, John Zizioulas and Vladimir Lossky, together with their Catholic counterparts like Joseph Ratzinger, Yves Congar, Henri de Lubac, Karl Rahner and Hans Urs von Balthasar. This study highlights their striking similarities and suggests, that from an ecumenical point of view, their common heritage and concerns in the world can be a basis for dialogue and the healing of memory.
