The entire community needs knowledge of "Church sciences" as none other are adequate to philosophical problems of which humanity became aware thanks to the progress of physics and philosophical logics in the 20th century. Ecclesiastical disciplines can do no less for Russia as it strives to settle its domestic problems. Russian universities and other secular educational establishments have a tremendous potential. They are able to inherit a tradition started by pre-revolutionary theological academies, which educated experts on disciplines crucial for understanding the history and contemporaneity of our post-Christian civilization as a whole, especially for countries of the Eastern Christian tradition.
