Concerning Marital Love

People, I think, have a misconception that marriage requires an erotic or philic love. Although I am unmarried, I think it requires much less than love, and much more (And I promise I'm not trying to be difficult in using such a paradox). Certainly marriage is a keystone of the Church. Without it, an element of Christian companionship would be lost. Still, the lower loves are not necessary for marriage. Too often people insist, that falling "out of love" is a reason to fall out of marriage. I insist in marriage that there is no need for being in love. Certainly it is wonderful to have such a feeling-- but feeling means nothing. True marriage is a duty (hopefully enjoyable) regardless of feeling.
My theory is contrary to the cultural sentiment of today- the sentiment that insists on finding "true" love, or such.
