This commentary on the Lord's Prayer has been complied from a series of broadcasts made by Fr Alexander Schmemann on Radio Liberty to listeners in the former Soviet Union. Because this single short prayer of Christ has everything that needs to be said about God, his kingdom, this life - about all of us - it is not an exaggeration to suggest that in this commentary Fr Schmemann provides us with a map for seeing anew the purpose and measure of our whole life. Fr Schmemann awakens in us a fresh understanding of these familiar petitions.
