This is one of the recent gems out there. Priest (2009) done with the support of the Russian Orthodox Church tells the story of Father Alexander Makovetsky who lives in present day Belarus during the start of the war. While I am not sure if it’s entirely historically accurate it does give you a view of Russian Orthodox spirituality, prospective, and to some degree practice. An Easter Sunday scene with Red Army prisoners celebrating service while Germans watch in, is one of the more memorable movie scenes you’ll ever see. Hope you enjoy!
Take a look!
