Although I'm using the past-tense, "was" here, it is possible that a case could be made that heretics should still be killed but I'm not the one making that case. I guess we first must ask; What makes a person a heretic? Typically you will hear that heresy is simply going against the predominant view, in this case against whatever expression of Christianity is dominant. This is where a person may claim that everyone is a heretic to someone else over some issue or another; thus making relativistic the entire idea. This is especially true of how the Roman Catholic Church and the Protestants have interacted. To this day, there are many Roman Catholics and many Protestants that do not consider the other group to even be Christians. But, I'm not trying to be ecumenical here.
HERETIC DEFINED
So, let us try to define heresy a little tighter. Romans 16:17-18 is perhaps the clearest biblical expression of what it means to be a heretic.
