‘Marriage is reserved by God for a male and a female. Period.’
marriage is a legal concept, not a religious one, as witness by the fact two non-believers can marry lawfully...in fact, marriage is whatever the legal authorities deem it to be, man and woman, woman and woman, ten women and fifteen men, twenty men and twenty dogs, etc...
what is reserved to man and woman, to you by God, to me by nature, is procreative sex...legality is irrelevant...
Doesn't matter whether you agree with God or not, a marriage is between one man and one woman. God is the creator, He makes the basic rules, not us.
