God defined it. It can't be redefined by any power on earth.

There is a government proposal to "redefine" marriage.

All Catholics and all who love God
living in Scotland
have to oppose this.

This is the only valid definition of Marriage:
The conjugal union of man and woman,
contracted between two qualified persons,
which obliges them to live together throughout life.

Marriage was instituted by God.

We read in Genesis that
God created them male and female,
and blessed them, saying:
"Increase and multiply";
and also:
"It is not good for man to be alone:
let us make him a help like unto himself.'

Adam said:
"This is now bone of my bones,
and flesh of my flesh:
she shall be called woman,
because she was taken out of man:
wherefore a man shall leave father and mother,
and shall cleave to his wife;
and they shall be two in one flesh."

These words, according to the authority of our Lord Himself,
as we read in St. Matthew,
prove the divine institution of Matrimony.

Not only did God institute marriage;
He also rendered it perpetual and indissoluble.'
What God hath joined together, says our Lord,
let not man separate.
