This seems like an incredibly convoluted issue, much more than it should be. To me, saying that what art is good or not, or acceptable or not, is determined by the “elites” in the art world is absurd. God is the artist of Creation. He made all beauty, and anything we identify as beautiful is only beautiful because God made it so. Despite our desire for it, we don’t have the power to give something beauty - it must already be there. So-called “elite” art critics simply run the business of art, which I find to be a disgusting term, and so they determine what is sold or not. They may know a lot about art. But that doesn’t mean they can definitively determine what is or is not art.
On another point: if the intention of the artist determines whether or not a photograph is sexual, how can we possibly know their intention? Wouldn’t the morality of a photograph be more about the photograph itself, what it elicits by its forms and structures, rather than anything imposed by someone else? And, if so, how can we identify this? For example, as others have said, nudity does not always equate to sex, nor does nudity in art necessarily mean the artist intended lust (I won’t say sexual arousal, since I find that too vague a term). So, how can we tell what the “message” of a photograph is - whether to invite lust, or to emphasize the beauty of the human body as an artwork of God?
Thank you all and God bless.
