My questions, primarily for theists but open for all discussion:
1) Should criminal charges be brought against paster Nelson Clark?
Should, yes, can, no. It would have to be shown that (i) the pastor had mens rea (a guilty mind) prior to the time of the death and/or (ii) he should have known that ignoring a medical cure would more than likely result in death.
His defence on the first charge would be that he firmly believed that The Lord would cure the child.
His defence on the second would be that he had, on many occasions, seen people recover through prayer.
In both cases, he knows he is not a medically qualified person and the parents knew this as well. To overcome this, it would have to be shown that the pastor had undue influence over the parents: the parents are adults and sane. Both the pastor and the Church believe the same things, therefore the pastors opinion was no more than that.
Is the Church guilty? This has implications for the freedom of speech.
What is required is a law to state that all ill children should be taken to a doctor for an assessment. However, such a law would be hard to frame: it would either require a parent to be able to diagnose an illness or prevent a parent diagnosing a cold and would prevent emergency treatment. The alternative is to ban any claim to be able to heal other than by a doctor. I can't see that being a vote winner in the US.
Lynch mobs can be useful.
