The word is vows, and there are no standards. You may vow anything you want.
There are three situations described by the word 'marriage'. The oldest is defined in the bible: Genesis 2:18 And the Lord God said, It is not good that the man should be alone; I will make him an help meet for him. 24 Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
The second is the public declaration, which is primarily for the sake of community stability.
The third is a three-way corporation of a man, a woman, and the state, for the purpose of making babies.
There is much confusion in the subject.
