In the Christian faith, marriage is viewed as a lifelong union of a man and a woman in the eyes of God. "..For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate." Matthew 19: 5-6
Virtually all Christian denominations frown on divorce, although some more harshly than others. But in most countries with religious Christian majorities, divorce is legally available and fairly common.
