NFP also involves sowing where the ground is sterile: the womb during periods far from ovulation.

Oh good grief. If that were practicing contraception, then it would be immoral for a couple to have conjugal relations if the woman were to old to conceive, or if the woman were infertile through disease.

If the woman is infertile through an act of God, then there is nothing wrong with excersising conjugal rights. It is when the act is deliberately made infertile that they are guilty of Onan's sin. Do you and FormerLib really not understand that, or are you just trying to confuse the issue on purpose?

I am saying that there is no moral difference between using methods to determine when the woman is infertile and many other forms of contraception. Clearly, there are forms of contraception which are not permitted due to an abortiofacient effect but that does not apply to ally of them.

I know that this is hard for some to accept as it will deprive certain people of one of their preferred methods of attacking Orthodox Christianity so I am not surprised that some will choose to die on the hill of "natural contraception" versus "artificial contraception."

Also, I am aware of any teaching of either church which demands that a married couple forgo conjugal relations once the female is no longer able to conceive. Are you suggesting that it is otherwise in the Roman Catholic Church?

I guess because its an emperical scientific fact rather than a papal pronouncement it doesn't count, but I'll say it again: Scrupulous keeping of temperature charts and measurements of mucous consistency as used to determine periods of infertility in NFP with intercourse taking place only during those periods deliberately renders the conjugal act infertile with greater probability than does the practice of coitus interruptus on a regular basis without regard to periods of fertility or infertility.
