Does the Bible actually support absolute morality?

Too many light-hearted fun questions on the site. Time for a good old-fashioned religion question. And because I’m feeling pensive, so…here goes.

A lot of people like to claim that the Bible supports absolute morality or just absolute truths in general. Yet these same people will turn around and say that the parts in the Bible that call for, say, our favorites like the death of homosexuals (Leviticus 20:13) or the genocide of multiple nations (Deuteronomy 7:1–2) were “written for the time they were written in” and that these guidelines were temporary.

So in other words, what was right for the ancient Israelites isn’t right for us. Therefore, morality has changed and it is NOT absolute.

So then why is this concept so difficult to apply to the modern day? Could it be that the part in the Bible that calls for women’s silence in churches actually be outdated? I find it interesting that some parts of the Bible can be outdated, and others can’t.

I realize I’m all over the place. Not trying to convince anyone of anything, just want to hear thoughts.
