There is one God and He is one. The one God is true, good, and beautiful. God is right in doctrine, practice, and aesthetics. An imagination that reflects who God is, a theocentric one, will recognize and accede, therefore, to what is true and good and beautiful.
Since God is one, you cannot separate any one attribute or quality of God from another. A particular imagination might be nourished or developed in the beauty of God, as testified by the aesthetics of that person. He loves the beautiful---beautiful art, beautiful music, and beautiful literature. That same person, however, does not manifest the same love for the true and the good.
Whatever God says is good is indeed good. A dress standard taught by God in His Word is good. If you reject modesty in dress, for instance, and yet profess to embrace beauty, you possess an incoherent imagination. Your view of God's beauty could not be coming from a moral imagination when that view contradicts God's goodness. A right view of God, a moral imagination, a Biblical worldview, a theocentric one, is coherent. You cannot separate God's goodness from his beauty.
You can read men online who are critics of an evangelical and fundamentalist imagination of beauty. They see an impoverished imagination almost indifferent to a theocentric aesthetic, as witnessed by deficient art, music, and literature. There aren't many of these critics. Most don't understand or care. And yet of these critics, some of the most ornery don't do good. They are hyper about beauty and dismissive about good.
Beauty is objective, that is, real beauty is found in the object, not just in the perception of it from the point of view of the subject. It is beautiful in itself. The same is found in goodness.
When someone forsakes goodness and truth, he forsakes beauty. If someone abandons one, he does the others too. God is one. Since He is one, His truth, goodness, and beauty are coherent. An imagination that deserts one for the others, in fact renounces them all. His world view is incoherent. It can't be coming from God. In a sense, it only borrows from a theocentric imagination for one aspect of morality.
If you hear someone tout beauty and deny goodness, he can't be believed or trusted.
