The age of the earth to literalists is based soley on adding up ages in geneologies. The early books of the bible (like ALL ancient manuscripts) have problems with numbers (first off), and Jesus (or possibly Paul) said something about Geneologies being unimportant.
The bible having problems with numbers doesn't hurt my faith one bit. When it says 30,000 men went out to battle, do I think that there were exactly 30,000? Nope, but I do think that meant there were a WHOLE BUNCH of them.
The 6,000 age of the earth is based off of adding up numbers from all over the bible. Essentially it is an interpretation, not pulled from one part of scripture, but from all over the place. I am not of the belief that it adds up to the beginnings of the earth, but it COULD darn well add up to the fall from Eden. You can string me up for it, but I believe that the story of Adam and Eve was about a whole bunch of people, before changing focus to a single family. Read it in Hebrew (or English with the knowledge that Adam and Man are the same word, and that word can be read as plural or singular), and note the implication that there were already whole generations of people in the garden (Genesis 3:16).
In many cases the church has doggedly held onto translation errors for centuries after they were known. Most bibles still say that Moses parted the "Red Sea", when the original text says "Yam Suph" which is sea of Reeds, or "Reed Sea", a different (much smaller) swampy body of water.
Sections on homosexuality are extremely clear. Read them in english, read them in the original languages, they are REALLY clear. The only way around them is to say that Paul's teachings, the law, and the story of Sodom were all false.
And also really, everyone harps on about homosexuality, when we view sex outside of marriage the same way. The people having sex outside of marriage outnumber the homosexuals 10 to 1.
Lying is the same thing, and that gets almost every one.
Idolatry is the same thing (getting a lot more people than you think, cough, sports, cough, arcade games, cough).
All sin separates man from God and has the same result. The sin of homosexual relations is no better nor worse than lying, lusting, stealing, or any other sin.
I know a married woman whom I feel a (quite natural) desire to sleep with. I have even had a few dreams about her. Does that mean it is not sinful to follow through on those desires? After all, they are NATURAL?
I don't see homosexuals as any different than I am. They have sinful sexual desires, and SO DO I!
