The contents of this book was originally given in the form of lectures at St Margaret's, Westminster. There is, we think, a special fitness in the lectures appearing in book form bearing the imprint of the Student Christian Movement, for though Father Nicholas has hosts of friends in Great Britain now, when he first came here our Movement was perhaps the only body which had the right to claim him as being already a friend. When the Student Christian Movement made its way to Serbia a few years ago, Father Nicholas became one of its first friends and, the year the war commenced and the following year, it was he who, on the Universal Day of Prayer for Students, preached by invitation of the Student Movement and its President, Dr. Marko Leko, to the students in the Cathedrals of Belgrade and Nish. Members of our Movement, therefore, will recognise that he comes under the category of persons so highly valued in the Student Movement, namely, that of senior friend.

Both inside and outside the Student Movement to-day people are thinking of the Church. Much has been spoken and written about the Church of Jesus Christ in our modern world, but not so much as to leave us unready to welcome this arresting and penetrating message from Serbia.
