What are Christian Heresies?

Count the number of current christian denominations. Everyone of them thinks that 99 percent of the others are heretics. ( Some, baptists for instance, think even 99 percent of their own are heretics.) If you are asking about the biggies that the church decided to murder everyone involved in then there are the Albigensian, Cather's, bomagils, Waldensian, arians, etc, etc, etc. You can look up the details on your own.
