Deep Thinker
Unfortunately, this subject would take far more time than I am willing to give it if we were to tease out all the issues (after all, the question of morality has never been resolved - that's why there are BBs and entire library shelves and web pages devoted to this very question
)
But just a points to ponder, and I will respond specifically if you wish to discuss this point further.
Mores go back to the very beginnings of
H. Sapien. We are a pretty weak animal and would not survive without community. Thus the earliest tribes developed rules which ensured the survival of the tribe.
These rules were codified over thousands of years by Tribal Shamans, perhaps attached to a deity, and ensured survival. Eventually writing came along and they were written down. But they do change over time.
Every tribe on the planet had/has survival rules which we call "morality". It is not limited to Mosaic laws (which in most cases are no longer used) or Jesus' sayings.
Before the spread of Christianity there were millions of people who had never heard of Jesus. Amerindians, South American Indians, Australian Aboriginals, Chinese, Japanese, Indians, Eskimos, Polynesians etc. etc.
Every one of these tribes had a form of morality which did not depend on Jesus, Buddha (well, not always from my list), Muhammed, or Roman rule for that matter. So, without a written code (and at least four of those I mentioned had no writing before Europe invaded), or knowledge of a common divine entit, they still had "morals".
So, long winded answer above, short answer below:
I got my morality from a combination of hard wiring ("moral" people, i.e. people who were more likely to have a tribal instinct) survived and living in a society based on our particular version of "moral" laws, to which I was attuned to.
Whether this came from Jesus, Buddha, Muhammed, or any other religious or secular teaching does not alter the fact of what we accept as morality. And, don't forget, different tribes do have different forms of morality.
