Well obviously anyone with those kinds of beliefs should be burned at the stake. You need to get them used to those high temperatures, eh?
I suppose Jesus told his followers to burn heretics at the stake somewhere in the bible, didn't he? After all Calvin was a sola scriptura kinda guy, wasn't he? He wouldn't have done that unless there was a scripture or two that could be interpreted to command the elders to burn non-trinitarians at the stake, would he?
BTW, do they burn Jehovah's witnesses in Presbyterian assemblies these days? I've never been to one, so I'm not really familiar with their sacraments.
The period we're discussing was a VERY intolerant age --
with wars of religion, inquisitions, sundry persecutions.
It wasn't until after the Thirty Years War (1618-48)
that tolerance gradually began to pervade European thought.
Of course, if one arbitrarily selects certain biblical
passages and interprets them according to one's own
presuppositions anything can be justified. This is often
a perversion of the teachings of Christ and tells more
about the interpreter than is does about the Gospel. The
theologians and philosophers call this "absolutizing
the relative". I know of no instance in which Jesus
advocated violence or execution against those with whom
one disagrees. Much more could be said about the psychology
involved in religious intolerance but that would take a few
volumes!
