The article is the presentation of the principal problems of Waclaw Hryniewicz’s religious thought. Since many years, in his numerous articles and books, this Polish theologian and ecumenist has been joining two great traditions of Christian West and East and trying to prove the necessity of contemporary, ecumenical dialog. For reader who knows the works written by priest, professor Waclaw Hryniewicz it is easy to notice that his theological reflection is pervaded through the spirit of Eastern Christianity, concretely speaking – Orthodox. In his theology one can also find references to Anglican and Lutheran thought, generally: protestant. But the foundation is the relationship with Orthodox Church. This relationship embraces the Christian East before the Great Schism, succession of Greek and Eastern Fathers. It appears, that dialogue with Christian East is the source of Hryniewicz’s theology. Besides direct references to philosophical and theological thought of Vladimir Solovyov, Nicolai Berdyaev, Sergei Bulgakov, Paul Evdokimov and Russian artists and writers as Andrey Rublov, Fyodor Dostoevsky, in many Hryniewicz’s statements one can feel the theological, philosophical and concerning of philosophy of history threads that since many ages had been analysed by great Russians thinkers and earlier by Eastern Fathers.
