[quote=Chrismasfetus]Just a response to your comment…
NFP should only be reserved for ***married couples ***who are eventually looking to have a family of their own. The use of NFP is a morally acceptable way to space out births or to avoid having children for the time being (due to a certain grave reason). It allows a couple to come closer together and love one another more fully because the use of artificial contraception is absent from their marital embrace. The couples do not “use” each other for only one reason —> pleasure. Couples who use NFP are always open to the possibilities of starting a family together.
This is very well said but I would change the ALWAYS to USUALLY. NFP as a tool is morally neutral – it can be used selfishly by married or singles alike. It is only allowed if the spouses have grave (that is the word in Humanae Vitae) reason to space or limit children.
“In relation to physical, economic, psychological and social conditions, responsible parenthood is exercised, either by the deliberate and generous decision to raise a numerous family, or by the decision, made for grave motives and with due respect for the moral law, to avoid for the time being, or even for an indeterminate period, a new birth.”
"If, then, there are serious motives to space out births, which derive from the physical or psychological conditions of husband and wife, or from external conditions, the Church teaches that it is then licit to take into account the natural rhythms immanent in the generative functions, for the use of marriage in the infecund periods only, and in this way to regulate birth without offending the moral principles which have been recalled earlier."
While it is true that NFP use might open one’s eyes to the beauty of the Church’s teaching on sexuality, its use before marriage is blatantly ignoring the teaching by engaging in behavior allowed ONLY in marriage.
