I only want to keep the arguments within natural law. The evil of contraception is said to be written in our hearts, yet almost the majority of civilization has no clue its even wrong. Wouldn’t it be more obvious?
A common argument against the Catholic position is sex can be used to bring unity and bonding to the spouses. That’s why it was made pleasurable. Procreation is only an option because procreating when one doesn’t have the means to sustain another living human is harmful.
What are arguments, from natural law only, to refute this?
