What Re-defining Marriage Really Means

"In reality, marriage is when a man and a woman freely chose to make themselves irreplaceable to each other. It is that choice that prepares them to receive a child, a new creation who is their equal. In reality, that child is irreplaceable to both of them and both of them are irreplaceable to the child. The child is an eternal witness to the one flesh union, carrying the flesh of his mother and father for all of eternity. The choice of the man and woman to marry started the circle of irreplaceability that we call the family."
