The Biblical view of marriage includes several purposes, the primary one being that God made the marriage covenant to mirror His covenant relationship with us:
God-Israel,
Christ-Church.
He made it the way He chose make it. It's really not up to me or you to *fix* it.
Procreation is another purpose.
Sexual fulfillment is one purpose.
Familial and societal stability is one purpose.
I may be leaving some out, but this is a fairly comprehensive list.
Marriage done right accomplishes God's purpose in His design for it and is a really beautiful thing to see.
You can disagree with the Christian vantage point, but I would ask you guys seriously to stop mocking it. I understand that you are not bound under the same authority that we are, but that is no reason to disrespect fellow man.
