What is a Biblical Marriage?
What is marriage? Altho I have left Christianity and no longer believe in the Bible, I have nonetheless years ago did a study about mariage in the Bible, of which the partial results are included in this short article. In modern Christianity marriage is looked on as a "sex license". In presenting the results of my Biblical research on the subject of marriage, it needs to be understood that I do not accept the Bible's explanation as legitimate, and to further complicate things, we have to add to that the problem of what a marriage actually is, or if it even exists in the first place. I am simply sharing with you the Bible's explanation, which is not mine. 

I discovered what a Biblical marriage is 
(even tho I no longer believe in the Bible) by getting my Strongs concordance and going through every place in the Bible that involved marriage and a dowry and I was surprised at what I found: It is the act of sexual intercourse that makes you married! So the question "Is it OK for a couple to have premarital sex?" is a pointless question because it is the act of sex that makes you married, so it is impossible to have premarital sex. So Christians need to apologise to people that they have wrongly accused of "living in adultery".

Genesis 29:21-30: And Jacob said unto Laban, Give me my wife, for my days are fulfilled, that I may go in unto her. And Laban gathered together all the men of the place, and made a feast. And it came to pass in the evening, that he took Leah his daughter, and brought her to him; and he went in unto her. And Laban gave unto his daughter Leah Zilpah his maid for a handmaid. And it came to pass, that in the morning, behold, it was Leah: and he said to Laban, What is this thou hast done unto me? did not I serve with thee for Rachel ? wherefore then hast thou beguiled me? And Laban said, It must not be so done in our country, to give the younger before the firstborn. Fulfil her week, and we will give thee this also for the service which thou shalt serve with me yet seven other years. And Jacob did so, and fulfilled her week: and he gave him Rachel his daughter to wife also.

Notice these phrases: . . .
he took Leah his daughter, and brought her to him; and he went in unto her. . . . he gave him Rachel his daughter to wife also. . . And he went in also unto Rachel . . .

Both women were not his wives until he had intercourse with them. Now let's move to Deuteronomy 22:28-29: If a man find a damsel that is a virgin, which is not betrothed, and lay hold on her, and lie with her, and they be found; then the man that lay with her shall give unto the damsel’s father fifty shekels of silver, and she shall be his wife; because he hath humbled her, he may not put her away all his days.

The giving of 50 shekels of silver is the dowry. What made her his wife? A ceremony, and written (unenforcable) contract, a court? It was intercourse that made them husband and wife. Here is a problem with the Christian teaching that you need a marriage license before having sex. A license comes through a court, even if performed in a church. There is no Biblical basis for requiring a legal contract issued by a court. Furthermore, a "marriage" as recognized by courts is a fraud because is it not two people who are being married, but two legal corporations. In law, whether you realize this or not, "you" are not you, but instead, "you" (who you think is the real you) is a corporation that was created using your name without your permission and created without your knowledge. In short, "you" (as the court views "you') are a corporation, not a living man. The legal term "corporation" is derived from two Latin words: corpus (meaning a corpse) and orat (meaning to speak). As the court sees you, "you" are a corpse that speaks. Courts only have legal duristiction over corporations. If however you represent youself in court as a living man, the court has no power or authority over you because you are outside of their duristiction (you are not dead). You can commit murder and have video evidence and numerous witnessesof that murder so that there is no denying it. Yet if you represent yourself in court as a living man the court cannot prosecute you, cannot hear the case and must release you. The lawyer you hire to defend you does not tell you this, and this is why all lawyers are dishonest. The world's expert on this subject is Dean Clifford who has many lectures on Youtube about this. The downside of him is his filthy language, otherwise he is worth listening to. Now to get back to the Biblical instances of marriage.

We find in 1 Corinthians 6:15-16: Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of a harlot? God forbid. What ! know ye not that he which is joined to a harlot is one body? for two, saith he, shall be one flesh.

What has made them husband and wife? A ring on the fingers, a ceremony, alegal contract? None of these. It was sex.

Now go to 1 Cor 7: 25, 28  . . . Now concerning virgins I have no commandment of the Lord . . . if a virgin marry,
she hath not sinned . . .

Notice that he did not say "Now concerning unmarried women". If you are a virgin the you are unmarried, hence he did not need to state this. This is because if you had intercourse with a man then you are married and no longer a virgin.

V.34: There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit : but she that is married careth for the things of the world, how she may please her husband.

Here again is the same idea: he did not have to say "between a wife and an unmarried woman".

Which is better: A Christian couple who legally "marry" (get a sex license), then divorce, then each remary someone else ( get additional sex licenses), or a couple who do not legally "marry" (have no sex license) yet truly love each other, are faithful, and stay together for their entire lives in a loving and caring relationship? A legal "commitment" means nothing, and about 1/2 are broken with no legal remedies or consequences. You can legally break the law (break your legal commitment, assuming that vows are given in front of witnesses) yet not suffer any legal consequences, nor is it even possible for the court to enforce this commitment, meaning that it is a legally worthless commitment, and so a legal "marriage" is also completely worthless.
