Ethics not Religion
Firstly let me say I am not religious and am a scientist by occupation.
Perhaps you would now be surprised to see that I applaud the church in this.
It seems to me that the real issue here is one of ethics not religion.
Is it right that we sacrifice unborn children to save existing lives? Who knows... at least the church is attempting to find some line to define acceptable and non-acceptable human behaviour, instead of sitting on the sidelines and whining.
With the new bio sciences and especially genetic science we are on the verge of opening a Pandora's box of new technology that can irreversibly alter the human genome itself. The responsibility attached to the use of these technologies is consequently enormous on a scale never dealt with by humans before. The advent of nuclear weapons and their corresponding threats and decades of fear were as nothing to society compared with the potential damage of bio and genetic manipulation this technology presents.
Why do I applaud the church's attempts? Because if someone doesn't deal with the very difficult decisions then it will be left to corporate (and by extension, governmental) greed, which knows no boundaries in seeking more profit and control for its own ends at any cost, including the total loss of all humanity and decency, and moral responsibility.
The bottom line is there will always be sick people who can benefit from some new technique. The 'do-gooder' mentailty that we should always do something just because we could no matter what the cost is terminally short-sighted. Just how far are we prepared to go just to extend someone's life? Is the abuse and termination of a new human life acceptable to extend an already relatively old human life?
This new technology demands that we need definite and clear answers to these difficult questions, and solid lines drawn beyond which it is ALWAYS unacceptable to go beyond. Perhaps the church has a role in helping define these moral boundaries. They have centuries of experience in dealing with morality after all.
Each time we allow the moral no-go lines to be fudged further, even in response to a touching case, we move irreversibly closer to condemning future generations to a genetically modified hell.
