I have nothing against Christian art, only that I want it to be properly Christian and not only Christian in name but pagan in nature, that's what I mean by aesthetic. Paganism knows aesthetics, and Christianity also knows aesthetics, but unlike paganism, Christianity knows that aesthetics is not the highest, and that compared to the highest, aesthetics is worth nothing. Many people, Nietzsche for example, get confused by it to the point of proclaiming Christianity to be "life-denying" while in reality, the exact opposite is true, foe aesthetic denies itself and needs the religious to be saved.
Morever I'd argue that Precure is pretty Christian by its nature. Way more Christian than, say, Goethe's Faust.
