Dictionary.com defines marriage as:
. the social institution under which a man and woman establish their decision to live as husband and wife by legal commitments, religious ceremonies, etc.
Canon Law defines marriage as:
The marriage covenant, by which a man and a woman establish between themselves a partnership of their whole life, and which of its own very nature is ordered to the well-being of the spouses and to the procreation and upbringing of children, has, between the baptized, been raised by Christ the Lord to the dignity of a sacrament.
Of course the definition of marriage in Canon Law applies only to baptized Christians, but even in the dictionary.com definition, we see that marriage has to be between a man and a woman. That’s the very definition of marriage.
To ask for a man to be married to a man or a woman to be married to a woman is to change the very definition of marriage. Or should I say, such a thing does not exist. There can be no real union between two people of the same gender, and there can be no real biological fruit from such a thing.
It’s not a marriage, so why call it a marriage? It does not fit into the definition of what a marriage is, so why call it a marriage? Call it “barriage” or something else, because “marriage” is reserved for a man and a woman.
