It is the church that gives you the structure to give your morality form. It is the group that you choice to identify with. Are you suggesting that Jews. Hindus, Buddhists etc are immoral?
Actually, Jonmeister, I had a pretty good sense of morality long before I fully immersed myself into the Church. Admittedly the teachings of the Church have no doubt extrapolated additional moral points for me, such as, “Since only God truly
creates and has commanded us to go out and multiply, it is, therefore, improper, i.e., wrong, to artificially thwart participation in his creative activity.” But, my earlier predilection for honoring the “rights” of others, pre-dated my full immersion into the Church, back when I was an atheist.
After considering the nature of man in his entirety, as best as I could, I determined that a “
right was that which I accorded to others precisely because it was reciprocated.” After immersion in the Church, it occurred to me that that might not be sufficient. That said, God does not hand to us our rights, rather, we draw them out of a consideration of human nature together with our purpose and the factical of reciprocity. In this manner, I cannot rescind my grant of rights to others, at least not morally.
You do give society authority - you choose to live by the laws of the land. You submit to societies morality. No one is forcing you to commit adultery and you are permissive with those that do. You submit to that authority even though you may think it is wrong.
A whipped slave also
submits. Again, submission does not necessarily betoken alignment with authority. The fact is, I was born here (USA). Here is what I am familiar with. Here, I have learned the ways of the street, so to speak. Here, I’ve learned to duck and dodge, besides learning what is against the law - that might get me into a world of hurt! Though I might not have submitted,
per se, my familiarity with here has caused me to become somewhat comfortable here. I do not want to begin a potentially new learning curve somewhere else!
You seem to think that society is stuck in time but it’s fluid.
And that can become, for its citizens, a severe problem.
Even the church has changed over time. (meat on Fridays, limbo, the inquisition, etc)
Somewhat true. The Church is organic. But, it still maintains its overall same-ness. The sources for that sameness may be causes for improvement or correction. For example, although meat is permitted on Fridays now, that derives from a more refined understanding of the entirety of the obligation for abstention. The overarching rule for fasting is still with us, but, a bit modified.
It is still society that makes the change. As the needs of society change, the structure to support those needs changes.
No. It is the people placed in charge who make the changes. In democracies, said changes are made occasionally at the behest of the citizens.

Most changes really do not reflect the people’s needs. They usually reflect the selfish wants of a vocal few. who know how to maneuver around the halls of government.
Like the Spartan example - The Spartans were a warrior tribe that the greatest good was strength and warrior ship, all morality stemmed from the support of those values. They also kept slaves. As did people in the bible, as did society in the US. None of them do now.
Some
values are not
moral. Some
morals are not
values. Some values are even achieved at the expense of appropriate morality. And some morality is achieved at the expense of some values. Consider the value proposition for genital mutilation. It certainly tends to keep women chaste. It permanently removes a God given/nature provided faculty. It is not moral. Morality has to do with intention, impious action, or both. Removing the faculty in advance of any potentiality of giving in to impious actions, is not considering the nature of man in its entirety. Clearly, not all women will give in to such impiousness. But, there, they never get the chance to reach a higher state - by their own volition. It is taken away by men, who appear to have no problem with raping. In fact, they get off the hook by publicly destroying the evidence! That betokens an immoral society from the top down.
Let’s pray for it. But, it hasn’t changed there for centuries.
God bless and Merry Christmas,
