Eg, killing is always wrong, a priori, but self-defense is an argument from experience due to the situation.
Actually, killing is not wrong
a priori, otherwise it would never be ok! The state may kill. People may kill in self-defence. If killing were wrong
a priori, surely the teaching that "the end does not justify the means"/"it's never permissible to do evil that good may come of it" would come into play even in self-defence situations. Murder is always wrong. And, as I understand it, the Commandment is really "Thou shalt not murder".
2) I think of the situation of breastfeeding like this, considering Mass is only maximum two-hours long, breastfeeding should and can be avoided. p
Breastfeeding isn't wrong
a priori! If it is necessary during mass, (cranky, hungry baby) and it can't have been prevented etc, then I suggest the use of a bottle, but if there is an issue with the temperature of the bottle etc., then the mother could withdraw to a cry-room or other place to do it. If none of these precautions are available then she can just do it discreetly.
What would Our Lady do? Bottle-feed? Though I guess, her baby was probably rather more co-operative than most!
I think there are a few issues that make people uncomfortable with public breastfeeding and these are:
-breastfeeding, like other bodily functions, by their nature are private and therefore people rightly have an uneasy feeling about it when displayed in the public sphere, and especially in a Church.
Has breastfeeding always been private, or are the hangups about it peculiar to our era and civilisation?
-breastfeeding is generally a distraction for the mother away from prayer and paying attention at mass, so for the mother's spiritual welfare, should be avoided - if possible.
Being stuck in a crying room with a crying baby would be more of a distraction from prayer! Breastfeeding is actually quite relaxing (once you've got the hang of it), and it shuts the baby up too!
All this having been said however,
As a church that encourages people to have large families, and especially as traditional catholics in general hold up the large families in our chapels as 'badges of honor" and rightfully so, i think that if breastfeeding bothers someone they should just try 'get over it' and be glad someone is having children these days.
That's more like it!
