Guest, observer -

You say: God instituted the cvenant of marriage. Where, please?
In both the mythical reports about creation (Genesis I and II) I can't find any hint.
In Gen. I he created man as male and female and commanded them to multiply and procreate (like the animals created before).
In Gen. II he created Adam (male) alone. Later on he stated (don't have my King James version with me here) it isn't good that Adam is alone and decided to give him a companion - not a wife! Marriage as an institution is not mentioned here.
Before uttering unproved allegations you should verify it in the Scripture (Dr. Martin Luther's approach).
Do you really want to deny a homosexual person the right to have a companion? What would Jesus say to that? (Thanks, Ebbie, you hit the mark.)
The first time I was confronted with this problem was when a homosexual companion in our Volunteer Fire Department married her friend. She was a reliable companion in fighting, and so she still is. I wish her all the luck in this covenant she is entitled to.
Then one of my daughters confessed to have the same problem. Shall I love her no more? And if she won't bring home a son-in-law, I have to be content with the companion she choose as my daughter in law, a nice and beautiful blonde I hold in high esteem.
