:The Roman Catholic Church does classify NFP as contraception (see Humanae Vitae), however classifies it as the only acceptable form of contraception (for casuistic reasons which defy my understanding – again, see Humanae Vitae) aside from total abstinence.
:To summarise the argument to date, I’ve offered Fathers’ views either condemning contraception and/or emphasising the essentiality of the procreative aspect of sex within sexual acts. You’ve tried to dismiss each of these, either by claiming that they’re not Fathers (Clement), that they’re too “Western” (Jerome, Augustine, Caeserius) or Western-affiliated (Epiphanius, Nicodemus), or that they don’t actually mean what they say (Nyssa, Maximus, Chrysostom). At the same time you haven’t produced a single Orthodox voice pre-20th century which endorses a single form of contraception. If I haven’t persuaded you on this basis (even regarding the ridiculousness of Evdokimov’s comment on the issue of birth control not being raised in the age of the Fathers), then I’m not sure I have much hope at this stage. Consequently, I’ll have to change tack. I’m assuming that we both agree that heterosexual anal intercourse within marriage is not good for a couple (please correct me if that is not the case). What exactly is it that is wrong about this kind of sex in your view? I ask this to find out the rationale behind your picture of sexual morality.--[[User:Gmharvey|Gmharvey]] ([[User talk:Gmharvey|talk]]) 10:32, July 10, 2018 (UTC)
===Is NFP rightly considered to be a form of "contraception"?===
You are mistaken. Nowhere in ''Humane Vitae'' does the Pope refer to NFP as contraception. The only occurrences of a form of the word "contraception" refer to prohibited techniques. And, "Neither the Church nor her doctrine is inconsistent when she considers it lawful for married people to take advantage of the infertile period but condemns as always unlawful the use of means which directly prevent conception, even when the reasons given for the later practice may appear to be upright and serious. In reality, these two cases are completely different. In the former the married couple rightly use a faculty provided them by nature. In the later they obstruct the natural development of the generative process" (sec. 16). Moreover, it is clear that the US Conference of Catholic Bishops believe that NFP is not a form of contraception. See http://www.usccb.org/issues-and-action/marriage-and-family/natural-family-planning/what-is-nfp/why-nfp-is-not-contraception.cfm/ The same is true of Pope John Paul II who, in his Apostolic Exhortation on marriage, ''Familiaris Consortio'', wrote: "In the light of the experience of many couples and of the data provided by the diﬀerent human sciences, theological reﬂection is able to perceive and is called to study further '''the diﬀerence, both anthropological and moral, between contraception and recourse to the rhythm of the cycle''': it is a diﬀerence whichis much wider and deeper than is usually thought, one which involves in the ﬁnal analysis two irreconcilable concepts of the human person and of human sexuality." Moreover, this is also the explicit teaching of the ''Catechism of the Catholic Church'', which approvingly quotes the distinction between NFP and Pope John Paul II in its Sec. 2370. Also, it adds in Sec. 2399 "The regulation of births represents one of the aspects of responsible fatherhood and motherhood. Legitimate intentions on the part of the spouses do not justify recourse to morally unacceptable means (for example, direct sterilization or contraception)."
