I see what your trying to say here but I don’t agree that the union within marriage should be viewed as a contract that the other partner won’t go out and cheat, but rather as a contract in love – to love, honour and cherish means physically, bodily, as well as spiritually. It means to give one’s partner your full attention – every part of you dedicated to every part of him or her, in intimacy. It’s the fact that there is fulfilment for both parties from feeling that loving, honouring, and cherishing, so that a healthy-minded adult wouldn’t want to go looking outside of marriage, unless it was by mutual consent between one another.
