I am going to play devil’s advocate because I think the last two posters made some good points, but others might counter it with the following:
Fix’s comments:
For a couple where the wife’s health is at risk if she becomes pregnant again, the Church clearly allows the couple to practice NFP and avoid pregnancy for the sake of her health. NFP is not 100% effective so the couple is risking in getting pregnant even when using NFP. So are they in fact morally required to abstain so as not to risk the health of the wife? The same could be said in this case; they are taking a risk as well in one person getting infected (btw herpes is a disease one could live with and manage all of one’s life with drugs, which might be less of a risk against life than certain women getting pregnant).
On your second point, I used the example to show the act of using a perforated condom is in itself not morally wrong if it can be used for medical purposes (btw preventing the spread of viral infections is a clear case of a medical purpose). So the action cannot be judged instrinsically immoral if we allow it in some cases. Now we have to judge the circumstance and ends of the act. The circumstance is that one of the spouses has a disease and the hoped for benefits is to prevent the spread of that. If using the condom was wrong inherently because it violated the morality of the act, then it couldn’t even be used to for semen analysis. It is considered an uncontracepted act so we have to judge the morality in light of the circumstance and the hoped for benefits or ends (just mentioned and so place you arguements there as to how it is immoral), not the act itself.
KCT:
I reference my earlier statement about using NFP with a women’s life or health in danger as stated earlier so it is important, but as you can see, couples still take risks and so if we judge its wrong for a couple to ever place the one of the spouse’s health at risk, then we must say that no one can practice NFP anymore to avoid placing the health of the wife at risk. Instead they must abstain from now on. Also, going back to the point of consequences from past mistakes, if I am not mistaken, people who have repented of voluntary sterilization are not required by church teaching to get reversals in order to be able to have sexual relations again so even in these cases of past poor moral decisions (and not all cases of herpes might come from this either), one does not feel the consequence is this light after repentence.
Still have not formed a moral opinion on this, just wanting to push the debate along and really get our morality mental caps thinking. The two of you may very well be right, but we won’t know until all the ideas have been exhausted. Keep up the good arguements.
