I've tried reading your post a few times, Stones, to see if I can work out just what it is that you are saying. I think you are saying that Christian faith is based on imagination, and science is based on facts, and that Jesus was being offensive in comparing people who do not accept what he taught as being "swine" (assuming that their hesitance is so strong that it leads to attacks on those promoting the teachings of Jesus), whereas there is far more justification for scientists being offended that Christians do not accept all that they teach as truth. Is that correct?
Quite apart from your apparent feeling that Jesus should not have said what he said, I will comment for the benefit of those who feel that Jesus DID have it right in saying what he said, whereas the problem may lie with how we interpret what he said.
Let's assume that Stone's approach amounts to rejecting something that Jesus taught (a pearl?) and that his criticisms of Jesus for having taught it (or perhaps of those of us who are inclined to support Jesus in having said it) amount to some kind of "rending". From what has been said earlier, the thing to do would be NOT to get into a debate with Stones, but to just interpret the warning from Jesus to mean that we should avoid any further debate. But (again, based on stuff that has been said in this thread) one might possibly discuss with other "believers" what they have done, i.e. that we felt the debate was heading nowhere, and so we walked away from it, in keeping with what Jesus said in that passage.
Of course, if we did that, then it still could get back to Stones (especially given that this is a public forum to which he is a subscriber), and so he would still be offended (and possibly rightly so in this case, if we were to interpret his simple arguments as a personal attack on those of us who believe Jesus was right in what he said).
I'm not saying at all that Stones has done anything wrong; but I am trying to work out how our comments would play out in a real situation where there is a disagreement, and where a word like "swine" is used (probably by both sides) in a way which offends someone.
I am thinking of another N.T. passage, where Paul says (to Titus, I believe) that we should reject anyone who is still a "heretic" even after two or three "admonitions". "Heretic" is another one of those offensive terms, though I've heard that it just means something like "argumentative" in that context. At least in Paul's formula, a few attempts are allowed before one jumps to the conclusion that it's not worth persevering.
Considering that one needs to use SOME kind of criteria to determine that someone else is rejecting the Pearl of Jesus' teachings, I think it's safe to assume that Jesus too expected that we would make two or three attempts to share that pearl with someone BEFORE we interpret their reaction to be that of a "swine", i.e. disinterest and something akin to aggression against what is being shared, thus causing us to turn away and ignore them.
What do others think about this application?
