I agree - if the "party line" of the Catholic Church is contained in the link you posted VQ how on earth do you, or they, expect non-theologians to hack their way through the undergrowth and understand what they are trying to say?
The trouble is that once you adopt the moral stance that the "soul" comes into being at the moment the sperm busts into the egg, you have an ethical problem with abortion. Because how are you, or anyone else, to decide that one "soul" is more worth keeping on planet earth than another "soul".
But along with the CC's opposition to contraception their stance on abortion appears, from where I am standing, to be a long-term cynical plan to ensure the maximum numbers of catholic births. More "souls" for heaven (sometimes rather rapidly, if the body was born into a third world slum) and if they happen to survive, more money in the coffers. Little catholic lives are very cheap if their mothers happen to be very poor. Doesn't matter about them getting the inside track to the gates of heaven - so why is it such a big deal to preserve the life of a foetus? And a foetus that is not even destined for catholic baptism!
As someone who does not believe in the existence of a spirit or soul of any kind, i think abortion is unpleasant and better avoided for all kinds of reasons, but when the chips are down, if it is a choice between a fully formed adult with an intellect and a personality and a potential person in the form of a foetus. No contest. But do they come out and say very clearly and concisely "the catholic teaching is to prioritise the mother and, if it is necessary to protect the mother from death or serious damage, a doctor should sacrifice the foetus"
And are you suggesting VQ that the stance of successive Irish governments on this is not driven by Catholic teachings? Or is it just a misogynistic conspiracy using Catholic teaching or lack of clarity as a convenient excuse?
