Have there always been marriage ceremonies to legalise marriage? Don't remember any really early accounts of this. Also how about today? Is a legal ceremony really necessary top be pleasing to God, as it is accepted by most governments nowadays that if a couple live together they can be regarded as 'common law' spouses after a certain period of time.
Even as I am writing this I am pondering on different ways of answering this so be interested to see your replies.
