Thanks, I think I get it now.:) I always wondered about that scenario (if the pregnancy must be "sacrificed" [in a way] for the life of the mother). Focusing on intention puts everything into much clearer perspective. I don't mean as far as "which is morally right," but as far as a basis for personal choices.

Intentions
 

I thought I had read that condom use is a no-no, even if the intention is to prevent disease and not pregnancy. Any one have insight into this?

Well, if you were both virgins when you got married and neither of you strayed, what diseases would you be preventing? I believe that's the logic. The only form of birth control allowed is the rhythm method. I suppose if you contracted something like hepatitis or HIV in some other manner and needed to protect your spouse from that, a priest would okay that. Or, if you had a medical condition that a pregnancy would exacerbate, birth control would be ok. But, I liked the way my first priest said it with "You need to pray and discern with God if you feel that you shouldn't bring a child into the world" (basically, it's between you and God)

Using a condom is a no-no. However in NFP if sperm needs to be collected, Then a condom can be used. HOWEVER (I am not making this up), the condom actually has holes in it so some amount can reach the intended target (therefore not preventing a pregnancy)
