Yes, that is what “tangible” is usually taken to mean.
But you can’t assess how holy someone is without committing yourself to some religious belief beforehand, which makes using that holiness as evidence for the religion a circular enterprise. For example, I can’t say something like “Look at how this person turned their life around by embracing the cardinal virtues. That means his religion is true.” This doesn’t work because “cardinal virtues” are a Christian concept to begin with, so I have to already be committed to the Christian philosophy before using this as evidence for Christianity.
It seems to me that your position of “tangible” as the criterion by which to judge the value of a person’s life is also a “religion,” which makes your argument just as circular. That someone’s life is valuable because of the amount of property they own, their status in society, their philanthropy, etc., is just as much a commitment to a presumed metaphysic (and fundamentalist “religion” replete with its own myths and presumptions) than any religious view, so I would have to be committed to some form of materialism before I would agree to your “tangible” criteria as evidence for an atheistic value system (if such a beast can even be inferred.)
Personally, I think it is self-evident that truthfulness, courage, self-discipline, temperance, faithfulness, generosity, wisdom, prudence, kindness and, in general, personal virtues are far, far more valuable than material goods. I don’t need to be a Christian to view a sound ethical system as superior to amorality. Though atheistic materialism doesn’t, by itself, provide any substantial ground for viewing personal virtues as valuable in themselves, but Christianity, and most religions, certainly do because these prioritize person over matter.
If reality is, at ground, intentional and personal, subjectively qualitative values can be inferred.
If reality is, at base, merely material in its essence with no teleological ends, purpose, or intention, no ethical or value system can be logically inferred. Atheistic materialism is constrained to IS, OUGHT does not follow. Certainly, an atheist can claim to be a moral agent, but atheism provides no logical ground or basis for being one. Indeed, atheism is quite compatible with serial killing and raping since any particular merely physical outcomes are no more or less qualitatively prescribed as better than others by the mere nature of matter.
There is nothing in the nature of matter that says organic is to be preferred to inorganic, living tissue to dead or a living human being to a corpse.
So your charge of circularity is just as applicable to your own atheism as to Christianity.
If atheistic materialism is true anything is permissible and nothing obligatory. No compelling, non-self-interested reason exists for acting morally. If you want to claim mere “tangible, materialistic results” should speak for themselves. Hitler would have been lauded by your ethical system had he succeeded in some tangible way in his quest.
That is the difficulty with prioritizing quantity over quality, tangible over intangible. Quality assumes non-material, metaphysical presumptions concerning inherent value. According to your argument, every metaphysical presumption, whether religion-based or not (and including your atheistic materialism) is going to involve a circular argument.
