This video covers Natural Family Planning.  This is an issue of extraordinary importance, since almost all people in the world use either artificial contraception or NFP.  A lot of new material is covered in this video: quotes from the fathers of the Church, answers to objections, interesting video clips, and much more.  Important issues are dealt with from beginning to end, and some of the most interesting parts come in the last 20 or so minutes.  Thus, we strongly recommend that people watch this video all the way through.
