I know that the secular world has their own definitions and guidelines for what constitutes a legal marriage, but what if those definitions and guidelines are not in accordance with Biblical marriage? Do you think we should honor secular laws that redefine and change God's original designs?
You have already been shown that the biblical marriage included contracts, written documents and records stored in the Jewish Royal Court and included more ceremonies than even the western version of marriage. It seems that you are wanting to ignore history and written documentation found in the rabbinical writings concerning the ANCIENT Jewish wedding details and claim it is not in the bible, which it is.
You keep appealing to an idea you have that is based on extreme.. and I stress extreme ignorance of the facts of Jewish weddings and claim that it is not in the bible when all those who are well read in biblical literature are wondering how you could have missed it.
I suggest you abandon your efforts of building a made-up theology about marriage based on ignorance and study the bible searching for these details that you thought were not there. Start a list. Once you have searched all the scriptures you will have discovered many details that you over looked. Some of which have already been pointed out to you but you seem to be rejecting them because they destroy your ideas that contracts and written documents witnessed by government (Jews had a government and kept records of marriages and no one doubts this who has read even one book on biblical history). Once you concede that this "lack of detail" you speak of is a phantom of your own imagination you can move on to the truth that contracts, written documents, witnesses, and even family approval was all part of ancient Jewish weddings and you cannot use Adam and Eve for your argument.
Stop pretending like your questions were not answered and trying to forcefully present an idea based on ignorance. Your line of reasoning is not persuading anyone but those who refuse to acknowledge the historical documented facts concerning the ancient Jewish wedding requirements you appear to be belligerently ignoring. I might have misjudged you but this is how your responses appear to me.
There is no question that written contracts and witnesses were involved in all marriages recognized by God and men in Bible times. Keep studying and you will soon be convinced that there is plenty of historical evidence for this.
Marriage was very much a societal event. It was never something done between a couple in secret. Appealing to Adam and Eve is an argument based on silence. We don't know what happened there because it is not revealed.
What we do know is that there were rules and laws in Jewish culture and they did not allow living together without marriage which included contracts, documents, recording in the Jewish courts and you seem to be attempting to ignore that and pretend "we don't know"
when we most assuredly do. You might not know but that does not mean these details are not known by those who have read about them. You just haven't got there yet. Don't run off and create a theory and be so cock sure about it before you have completed your research or you will soon find that your entire theory was based on ignorance of well documented historical facts. Stay humble and keep reading before you form an opinion. And by all means listen to those who are trying to steer you away from any idea that could be considered sin. Don't get near a questionable theory that might result in rebellion against the known will of God.
This whole pushing an idea that is based on ignorance of history is glaringly obvious to those who know the history of Jewish culture.
You brought the topic up as if you wanted to know, and then when you find out that there are historical records to prove that the Jews had marriage contracts, written documents, and requirements that had to be met for marriages to be RECOGNIZED BY SOCIETY you seem to come across as if you want to "pretend" like none of these facts contribute to the answer "what is a biblical marriage" when they most certainly do.
Bottom Line. The idea that needing a license, exchanging vows, witnesses, state recognition, recording of documents of official weddings is not biblical is based on extreme ignorance. Sorry if that hurts but sometimes a little pain is required for us to self correct. And hopefully learn from our mistakes.
