I take Andres Serrano, the artist, at his word when he claims that the photograph"alludes to a perceived commercializing or cheapening of Christian icons in contemporary culture." Piss Christ - Wikipedia, the free encyclopedia
Let's look at the photo:
I would like to see an artist made print of the photo to see it in the color and saturation that Serrano intended. This scan probably does not do the original justice.
I think the image is well composed and has a soft quality that makes the crucified Christ look even more tragic than it would out of the urine. The lighting particularly is well chosen. To me, the photo says that the sacrifice of Christ on the cross retains its dignity, perhaps it is even enhanced, by the degradation and marginalization of the crucifixion in popular culture.
All Christians know that persecution is coming, because it has been foretold. We must all expect to suffer for His name. Serrano, whether intentionally or unintentionally, has made an artistic statement about that very reality. Through it all, Christ's sacrifice retains its deep significance, and our salvation is not diminished one bit by the slings and arrows of those who hate or trivialize the word of God.
