The word “missionary” is already commonly used to refer to Catholics or Protestants, Americans or Koreans. But here we have a book written by a missionary of the Russian Orthodox Church. And this book is not about what happened in past centuries, but about how today to have a conversation about faith with someone who is ready to ask about it, but is not yet ready to agree with it. And this is a book not about other people’s victories or defeats, but about our own. Its author is a professor at the Moscow Theological Academy, who often lectures not there, but at secular universities (he visits a hundred cities around the world a year with lectures). His books have already sold over a million copies and have been translated into many languages. Despite the fact that the author addresses this book primarily to his students (seminarists), its plots are interesting for a variety of people. After all, we are talking about how we hear or do not hear each other. Each of us is at least sometimes a “missionary.” So how can you make your views understandable to a person who obviously does not share them? A grain of two thousand years of Christian missionary experiment is reflected in this book.
