Is Divorce Unconstitutional?

One of the objections to divorce has been the role the State ends up having in what's often considered to be a religious affair.  This would seem to go against the First Amendment (Congress shall make no law respecting an establishment of religion). 

However, marriage is often regarded as the building block of a family and therefore of society.  It is regarded as a civil contract.  In Sharma v. Sharma, the court held that in divorce procedure, only the civil contract aspect of marriage was being dismantled, not the ecclesiastical union.
