Many catholics, I'm afraid, are taken in by the church's repeated appeal to "Natural Law" It sounds very impressive----"natural" and "Law"----what more could you want. I am sure the heirarchy is quite confident that the laity in general has no idea what natural law is. Natural law is a very complicated subject. Basically today the church uses it to oppose any type of contraception, or "artificial" contraception by claiming "natural law" clearly shows that the main purpose of sexual activity is procreation. Now to go from sexual intercourse can , in limited circumstances, "create" a baby to that is the basic function of such activity is similar to arguing 'tornados' in some instances cause damage thus the "purpose" of tornados is to damage property.
It is interesting to note, as I have before, that the great "natural law" philosopher of the church, Aquinas, believed rape and masturbation are at least equal because the former at least had the possibility of procreation. Aqunas was brilliant, but starting with a fase premise supposedly from "natural law" that the main purpose of sex is procreation---he comes up with an obvious absurdity.
What "natural law" says sex is primarily for procreation? Any particular act of intercourse has a very, very low possibility of fertilization. Out of 8 reasons for sex a survey showed that pregnancy was the number 8 motivator. Also it should be noted that the papal commission set up to review contraception, came back with a recommendation that the church's position be modified but Paul6 turned it down.
Our Church does nothing but lose respect with its attitudes on sex. What our church might acheive if it could get off its sex phobia!! Jack
