I presume you use natural health practices as well and reject the use of modern medicine.
Just let nature take it’s course and stop interfering with God’s will, eh?
Medicine is for restoring the function of the non-functional organ or system. Curing the sick. Straighening out the abnormal. Stengthening a weak power.
Contraception is for impeding the functional. Drugging the healthy. Altering a normal system to make it work abnormally. Weakening a natural power.
Contraception is not legitimate medicine. It treats a healthy woman, robustly female and complete in every detail, as if her full sexual function were a disease.
Fertility is a sign of health in every species. With wisdom and appreciation, you can cooperate with its delicately-balanced, elegant structure, either to achieve or to avoid pregnancy. Or you can throw a monkey-wrench into the structure.
The purpose of contraception is to be that monkey-wrench.
It treats our bodies' beautiful design, inside and out, as a glitch, not a feature.
It treats women's generative power as an abnormality to be doctored, altered, and "fixed."
