Yes it is grotesque...repulsive and offensive. Looks like something pagans would have designed centuries ago...or something the environmental weenies would celebrate.
It is demonic in origin, when one studies where and how the demons will be released from the Earth during the last of the Tribulation. The sculpture is straight from a demonic scene in Revelation ... hideous, yes, but seems appropriate to have it so prominently displayed in The Vatican for the Popes to sit before.
Was it crafted by the same artist that put a crucifix in a jar of pee?
