Extramarital Relations Using Contraceptives
The actual reason is to protect the institution of family which requires a man and a woman to raise their children with complete devotion. In extramarital relationship it is not possible to establish complete devotion. Rivalry, preferring one to another, emotional attachment and detachment with different partners, switching a favourite from one to another, etc, doesn’t allow to establish a family unit where children need complete attention from both their parents. For the same reason, illicit relationship before marriage is not allowed too, as precautionary measure.
I understand the part of not raising children outside of marriage. My focus is on the precautionary measure. If it is 100% guaranteed no children will be involved (conceived or adopted) what THEN is the reasoning/rationale/justification behind forbidding extramarital relationships?
If one develops extramarital relations, he or she won’t be able to satisfy the sexual needs of their spouses and also this interest in others will affect the raising of the children. If the person is not married, but he or she will marry one day to raise a family, this habit should not be developed and has to be avoided later.
