It seems that you keep trying to bring abortion into this discussion. Abortion and contraception are two very different topics. I think you would find that we have much more common ground on the topic of abortion. That, however, is a for another thread. Could we please stick to the topic at hand.
There is no change of topic involved. I make the point that in Catholic Moral theology, we accept that some acts are “intrinsically evil” - that is, there are some acts which are always wrong to choose. I mention abortion - an intended killing of an innocent - as I expect you agree that it is always wrong - it’s a moral truth that doesn’t change. *Good intentions or particular circumstances do not give rise to occasions when it becomes an acceptable act. * Calumny, fornication, adultery, contraception - are also taught as “intrinsically evil”, though I’ve already acknowledged that in connection with contraception, you believe contracepted sexual (marital) intercourse is a moral act.
If this is truly how you believe then I think you have missed the major point of the Gospels of Christ. Moral precepts do not exist in a vacuum. They are interwoven with other truths, circumstances where they are applied, the effects and many other factors and they do not trump the need to regard our neighbor with compassion, love and understanding.
You need to direct your criticism then at the Church, for she holds that the negative precepts of the law (Thou shall’t not…) are in fact absolutes, while the positive precepts (Love they neighbour…) are not. From
Veritatis Splendor:
*“The Church has always taught that one may never choose kinds of behaviour prohibited by the moral commandments expressed in negative form in the Old and New Testaments. As we have seen, Jesus himself reaffirms that these prohibitions allow no exceptions: “If you wish to enter into life, keep the commandments… You shall not murder, You shall not commit adultery, You shall not steal, You shall not bear false witness” (Mt 19:17-18).” *
The Church does not forbid couples who have the proper motivation and disposition to time the birth of their children and to limit their family size. It simply says that the only two options for them to do so are abstinence and Natural Family Planning. We both agree on this point I think. I simply believe that the difference between some (not all) of other methods of timing the birth of their children and limiting their family size amounts to semantics and artificial subjective constructs …
The Church identifies that abstaining at times from intercourse is quite distinct from modifying the natural course of sexual intercourse to remove its procreative characteristic - and gives its basis for concluding that such action is immoral (see for example:
Humanae Vitae para 10 - 18). I find your assertion that acts such as: - donning a condom prior to intercourse, or mutual masturbation, or taking a pill to prevent ovulation prior to intercourse - differ from abstinence by merely “semantics and artificial subjective constructs” to be patently absurd. They are demonstrably and meaningfully different. It is enough for you to assert you disagree that these acts are immoral. I accept that you do.
Even a woman who has a tubal ligation may be open to the possibility of life. All these procedures have a known failure rate. If the woman who has had this procedure becomes pregnant and accepts the resulting pregnancy as God’s gift of a human life, bears the child, loves and nurtures him/her then it may be said without equivocation that she was indeed open to the possibility of life.
Tubal ligation is a form of sterilisation and if its purpose is to render future anticipation sexual intercourse sterile, then it is clearly contraceptive. That the person concerned - should they actually become pregnant - then chooses to
not abort the child, they have rejected the sin of abortion, and that is good. This does not change the nature of the act of sterilisation, which is the same kind of act whether enacted prior to the birth of any children, or at some later time. This does not mean that the degree of evil is the same in both instances. But the fact of existing children (a circumstance) does not cause the contraceptive act to no longer be wrong.
If the family of this woman have all the children they can raise given their circumstances then they have also accepted the moral precept that the purpose of marriage is procreation. Application of the moral precept that the purpose of marriage is procreation does not mean that you should keep having baby after baby far beyond the number you can nurture and care for or till birthing complications kill you.
There is no suggestion, explicit or implicit, that one should “keep having baby after baby…”. So this is a strawman.
