In the Christian faith, marriage is viewed as a lifelong union of a
man and a woman before God. One commonly used text is from the
Gospel of Matthew (which is itself a quote from the book of
Genesis).
"...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 (quoting from
Genesis 2:24)
Virtually all Christian denominations frown on divorce, although
some more harshly than others.
Christian marriage is seen by St. Paul (especially Ephasians
chapter 5) as paralleling the relationship between Christ and the
Church, a theological view which is a development of the Old
Testament view that saw a parallel between marriage and the
relationship between God and Israel.
