Christians perceive only one kind of relations - between a man and a woman and there is no alternative for this. Other variants are not considered as marriage among Christians. They deny all kinds of living together, but it is not new, it is like this since ancient times. So there is one standard marriage among Christians created by God.
Every wife should submit to her husband - this is the first rule. That means that husband should take the main decision and take all the responsibility. What are the advantages of it? They are the following - no arguments, no rows in the family - there is no ground for it. It will be good for both partners and children who are brought up in a good atmosphere.
A man should love his wife. A wife ought not to prevail her husband. She must obey a husband.
A marriage is a symbol of welfare in the world. Welfare in the world is when people do what they are dictated to do by God. Welfare is when a house is cosy, children are well-groomed and there is someone to take care of them. It is God who created happiness as harmony in the family. That is why a man and a woman must be together. Emancipation of women is not approved by God. If a lady doesn't want to be submissive to a man she contradicts God.
These are the main principles for Christians.
