Divorce

Divorce is much more than an official ending of a marriage by an official decision in a court of law.

1Cor 7:10 - 16
To the married I give this charge (not I, but the Lord): the wife should not separate from her husband
(but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.
To the rest I say (I, not the Lord) that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her.
If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him.
For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. Otherwise your children would be unclean, but as it is, they are holy.
But if the unbelieving partner separates, let it be so. In such cases the brother or sister is not enslaved. God has called you to peace.
For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?

Mar 10: 2 - 9
And Pharisees came up and in order to test him asked, "Is it lawful for a man to divorce his wife?"
He answered them, "What did Moses command you?"
They said, "Moses allowed a man to write a certificate of divorce and to send her away."
And Jesus said to them, "Because of your hardness of heart he wrote you this commandment.
But from the beginning of creation, 'God made them male and female.'
'Therefore a man shall leave his father and mother and hold fast to his wife,
and the two shall become one flesh.' So they are no longer two but one flesh.
What therefore God has joined together, let not man separate."
