Question: Is adultery, as defined as marraige outside wedlock, something that occurs only after one has married?
1 Corinthians 7:2-5 is a section that speaks of marriage as the answer to those who do not have the gift or ability to live without sexual activity. That solution is marriage and having sex with your life's partner, not simply becoming sexually active. Hebrews 13:4 is a strong passage that on the one hand speaks highly of the marriage bed (sexual activity within marriage) and on the other hand flatly condemns sexual activity outside of marriage. (The Bible words usually translated "adultery" may refer to a wide range of wrong sexual behavior, whether by those married or unmarried.) And all the passages that refer to marital unfaithfulness (like Matthew 19:9) assume sexual activity within marriage while condemning such activity outside of the marriage bond.
Question: Is pre-marital sex adultry in the eyes of the Christian God?
The basic passage is Genesis 2:4 which is also quoted by Jesus in Matthew 19:6. God instituted marriage to be a union of one man and one woman. The man is to leave his father and mother and be united to his wife. Only then do they become one flesh to enjoy the blessing of sexual intercourse that God gives us in marriage. Heb 13:4 and 1 Co 7:2-5 also speak about marriage as the only place where God wants his gift of sexual intercourse to be practiced. The better way to translate 1 Thess 4:3-5 (instead of "control his own body" in the NIV the words should read "obtain a wife") also speaks to this point.
Question: Is adultery contradictory to polygamy?
If you define Adultery as being an immoral sexual act. The Bible never explicitly prohibits polygamy, but it does state God's original intention for marriage: one man and one woman in a one flesh relationship. It also illustrates the ill results of polygamy. Romans 7:2-3 shows it is wrong to marry a second spouse.
Question: Is adultery actually a man made concept to promote monogamy and one not given by God?
I am not sure what you mean by this since God promotes monogamy, as does a majority of man made laws.
Question: Biblical charachters were polygamous and holy men, does that not mean marraige is not specifically a monogamouos union?
Almost all of the patriarches in the bible were married to only one women. Any adulterous relationships, or even marriage to more then one women never worked out in the long run, and often caused more harm in the end. For Abraham, none of his offspring other then the one to Sarah ever inherited Gods promise of a savior being born to the line. For Soloman he fell into sin, and the Kingdom became divded, and evetually destroyed.
If you do have Luthern background, wouldn't it have been easier to look at Luther's Large Catechism: 6th Commandment?



Thanks for the link.
