The Holy Father's teaching seeks to make clear that, without a fundamental mutual respect and devotion, any sexual act between a husband and wife is a counterfeit of the real thing. Such an evil act is not what the Lord of Life wants human beings to contribute to the creation of a new life. A woman who has no way to escape such abuse is morally justified in resorting to effective, non-abortifacient but medically effective means to avoid being impregnated.
