Since sexual ethics concern fundamental values of human and Christian life, this general teaching equally applies to sexual ethics. In this domain there exist principles and norms which the Church has always unhesitatingly transmitted as part of her teaching, however much the opinions and morals of the world may have been opposed to them. These principles and norms in no way owe their origin to a certain type of culture, but rather to knowledge of the Divine Law and of human nature. They therefore cannot be considered as having become out of date or doubtful under the pretext that a new cultural situation has arisen.
