Most people think NFP is guessing. Fact: Modern methods (Creighton, Marquette, Sympto-Thermal) monitor biological markers (hormones, temperature, mucus) to pinpoint ovulation within hours. It is fertility awareness, not guesswork.
Why Not Contraception?
Contraception says: "I give myself to you... except for my fertility." (Conditional love). NFP says: "I give myself to you completely. But we will abstain this week for a serious reason." (Sacrificial love). One breaks the procreative power; the other respects it.
