Question: Can an unmarried woman, who is not sexually active, use the contraceptive pill for a medical purpose?
Answer: Yes. When the contraceptive pill (the birth control pill) is taken by a woman who is not sexually active for different medical purposes (other than hindering the conception of a child), the pill does not deprive sexual acts of the procreative meaning, because there are no sexual acts. Since the person using the contraceptive pill does not perform the sexual act that always must be excused with the motive of procreation, the moral object is not evil, and the usage of the contraceptive pill is not intrinsically evil.
