Spike - thanks for your reply but it doesn't answer my question.
The bottom line is this - if you belong to an organisation that stipulates that you do not undertake a potentially life saving medical procedure, then you may die obeying this command. Let's say that this organisation readjusts it's thinking and policy in the future so that now there is some leeway. Clearly it follows that people have lost their life from obeying an organisational rule that is now considered out of date. Imagine the torment of people who have lost family members needlessly.
For an organisation to say - ' sorry, we've reviewed the policy now - sorry about your dead relatives ' is beyond contempt and morally reprehensible. This is clearly out of step with the teaching of a loving God.
Euthanasia is an entirely different premise. This path should involve choice, when someone feels that their life is being made intolerable by illness or other related issues. Children who die through not receiving a blood based life saving treatment have no choice or say in their own mortality.
