Most famous Christian art (music, fashion, sculptures etc.) is boring, repetitive and (in my opinion) doesn't usually reflect the greatness of God's glorious art.
Look around you. All that God made in this world is beautiful, and as human beings made in the image of God to reflect his nature, we honestly do not make good art that glorifies him. Most Christian music, for example, is the same thing repeated over and over. Now, I am not saying it doesn't glorify God, but I know a lot of Christian art is made just for the money or just lacks creativity.
And I think this spans to other aspects of art as well: Fashion, Food, Theatre, Film, Architecture, and even paintings and sculptures (though there are a lot of good old ones from great artists).
Can you guys show me good Christian art that is just as good, and in fact better, than its secular counterpart?
