What is the purpose of going outside the Bible to prove that the Bible is true in the sexual area? I've already demonstrated to my satisfaction that the Bible speaks truth in all areas.
Let's give an example of such reasoning:
1. Wave a magic Bible wand so that all unmarried persons obey the Bible (no sex before marriage, no sex outside of marriage). STDs are gone. Poof! Divorce rate plummets. Poof!
2. God is right.
3. See # 2 above.
4. No, stop arguing, see #2 above. Read #1 more slowly this time, too.
If you are taking my evidence for a "no" then your comment about my honest was sarcasm, not appropriate since I did the following:
1. Said I don't need to go outside the Bible to prove illicit sexuality is wrong, based on my knowledge of the Bible as always relevant, always truthful.
2. Went ahead anyway, out of courtesy, to explain how biblical limits on human sexuality will bless marriages and end STDs.
3. Do you want peer-reviewed papers "proving" that fewer sexual partners helps curb STDs? That monogamy strengthens (most) marriages? Really?!
Your claim that the Bible is always right is just that ... a claim. It isn't evidence. You are using the claims of biblical authors to support your claims.
That is untrue. I gave two examples: marriages helped and STDs curbed by following the laws and precepts in the Bible regarding human sexuality.
