"In the pages that follow, the reader will find a concise and rewarding history and overview of the Holy Orthodox Church, which describes and illuminates God's salvific and providential love for the world...the book is a concise text that is as accessible as it is accurate. History, aesthetics, liturgy, theology, key persons, and events punctuate the text and create the 'window' of which the title speaks." -From the Forward by His Eminence Archbishop Elpidophoros of America.
