If love is not on the list, I would question the list, not love. Jesus said, "No greater love has any man that this that He lay down his live for his friend". On that basis, I can look at any moral question and ask is it love? And in this case, diluting marraige is not love and definitely harmful to children.
If we can't come to an agreement of the need for the institution, it will die away and be abolished just as King Hamekameha abolished taboos once no one remembered the basis for the taboos.
I don't know this King Hamekameha, nor how he would abolish taboos from the human race by what you are saying here. Or how marraige, created by God could be abolished by mere man. What I worry about is the effects of this adulteration of marraige on our country, our children and our future.
"Vitures based ethics" is very valuable based on the person of the Lord Jesus Christ and His word. Because it allow you to stand on a rock and pull others to safety, while the rest goes into sinking sand.
Take the high ground my freind and not those of the moral reletivists.
That is the problem. The institutions of marriage are collapsing leaving some kind of economic hedonism to rush ionto the vacuum. You can point to a major public event such as the assassination of JFK as the critical catalyst of our downslide, but in fact it has been a continual series of events dating back as far as one wants to go that brought us to our present state, not that we will stay long in our present condition.
