But if you reject (or simply ignore) BRAHMAN (or NOUMENON), a necessary being, what is the objective standard of appeal?
An appeal to brute fact! Wow!
You keep speaking of this noumenal self as a necessary being, Brahman, an unknowable being. What exactly is Brahman like --> "Unknowable!"
You claim Brahman. How do you know this god exists and is not wishful thinking? What has this god revealed for you to know of its existence? Is this god a personal being? Not according to some Hindus.
"Brahman, a term used in Hinduism for God Almighty, creator of entire cosmos was always impersonal, a source of magnanimous primordial cosmic energy beyond human comprehension."
"The Vedas conceptualize Brahman as the Cosmic Principle.[10] In the Upanishads, it has been variously described as Sat-cit-ānanda (truth-consciousness-bliss) as well as having a form (Sakar)[11][12] and as the unchanging, permanent, highest reality.[13][14][note 1][note 2]" Even in Hinduism, some believe Brahman is a personal being while others do not, depending on the school of thought, which again brings to mind the question of how does anyone know? But what has the Vedas or Upanishads given humanity to confirm Brahman? Far, far less evidence than the Judeo-Christian God, and a god that contradicts the God of Christianity.
And Kant's idea of the noumenon begs the question of how he knows this?
"In Kantian philosophy, the unknowable noumenon is often identified with or associated with the unknowable "thing-in-itself" (in Kant's German, Ding an sich). However, the nature of the relationship between the two is not made explicit in Kant's work, and remains a subject of debate among Kant scholars as a result."
So, what the "men of Athens" (Athenians) worshiped as the unknown God the Apostle Paul made known to them.
For while I was passing through and examining the objects of your worship, I also found an altar with this inscription, ‘TO AN UNKNOWN GOD.’ Therefore what you worship in ignorance, this I proclaim to you.
Starting with human thoughts as the point of reference to the noumenon gets you no closer to the truth, thus we need a personal Being to reveal the truth to us. That is, ontologically speaking, in regard to the truth about the universe, the truth about us, and the truth concerning morality. So you can think the noumenon is necessary but you are still not there unless this infinitely omniscient Being chooses to reveal what is the case to you. If this infinite Being is not conscious or personal you are left with a force or mysterious source of speculation. Something that just is, without mind, without personhood, is incapable of revealing anything. The Christian God meets the requirements of knowing like no other religious system of thought.
"Kant had to develop a philosophical perspective that destroys the intelligibility of any objective knowledge at all. This reflects the desperation of those who intellectually oppose the faith. They would rather be reduced to subjectivism (eg., the projection of the unknowable "noumenal" self) than to acknowledge their responsibility before God, whom they very well know and cannot escape."

You don't have one.
There is no such thing MORE purely OBJECTIVE than NOUMENON.
How has this been revealed to you?
It becomes a preference.
EXACTLY LIKE YOUR PREFERENCE IN YOUR CHOICE OF GOD($).
First, it is not based on me. I appeal to a source of revelation outside myself, a necessary personal knowing and revealing Being. What are you appealing to with your statements?
Your "justification" of your GOD($) is de facto "justification" for your ("invisible") moral code.
By necessity in making sense of morality, yes. I invite you to make sense of why what you believe, morally speaking, is any better than that of anyone else, unless you have an objective, omniscient, revelation. Go ahead!
(IFF) you are unable to convince someone that your moral code is universal and unchanging (THEN) your moral code is a de facto OPINION.
Some people cannot be convinced because it runs contrary to what they want to believe.
There is proof available in and for the Christian worldview that is most reasonable. It comes from what is necessary for there to be morality. How is yours anything other than opinion?
It becomes a preference.
Just like your preference for a particular god($).
The evidence is convincing and justifiable. Christianity has what is necessary. I can make sense of morality. Show me your belief can too.
How does what you like (your subjective tastes and desires) equal what is good?
Well, I certainly wouldn't trust you to tell me my likes and dislikes.
You are evading the question, trying to turn it back on me to escape explanation. It is a ploy I have witnessed for those who have nothing to offer use.
It doesn't and as soon as you lose or deny the 'best' that you compare morals against (as necessary) you have disagreements that contradict each other.
The decalogue doesn't resolve these disagreements.
Sure it does. An omniscient, unchanging, eternal, objective being who has revealed most certainly does.
(IFF) everyone agreed on the one-true-interpretation and practical application of the moral code of "YHWH" (THEN) we'd all be Orthodox Jews
Argumentum ad populum. Truth is not true just because the majority think so. What is good is so whether you believe so or not.
How can you distinguish what is better without this best?
Quite easily.
Start at the "worst" and take it one step at a time.
Worst in comparison to what?
