please answer my question first: what is "arbitrary and meaningless" about saying that avoiding pregnancy is not intrinsically wrong but contracepted sex is intrinsically wrong?
Please allow me to interject; I find Gishin's stance on the issue to be reasonable, but his attempted answer to this question incomplete.
Contracepted sex, by any means, is avoiding pregnancy. To pretend there is a difference is ... well, I have yet to see a reasonable attempt to justify any such distinction. (And "because the Pope said so" doesn't hold water here.)
Further, contracepted sex is "sharing yourself as fully" as non-contracepted sex. With the only distinction being not "sharing" responsibilities the couple is not ready to handle. (Somehow I fear the point must be stated that if every time any sexual act occurred that a child was born, that our planet would be in a heap of trouble!)
in the first case one can be practicing self control with the intention of safeguarding the health of the spouse out of true love. it can be an act of truly loving restraint, as opposed to using someone
For the benefit of the unbelievers here, they have educated a RC on what the Bible says on this topic:
"women did change the natural use into that which is against nature: (Romans 1:27) And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly"
Use is not unnatural, but natural. And Blessed within marriage!
"Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband. (1 Corinthians 7:4) The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.
Defraud ye not one the other, except [it be] with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency."
Personally, I would be embarrassed to have the unbelieving crowd here show me up on understanding such simple matters within the Bible; but this issue is missed by so many within the household of Faith ...
