John_Mann - Bishop Barron is either stupid or dishonest.
You already know why his waffle does not even begin to answer the challenge. He lyingly pretends god did not cause the tsunami he only permitted it. Even if that were true - and it isn't - that still makes god a moral monster.
The god of Jesus created the world complete with moving and sticking tectonic plates. We know that continents have been on the move for millions of years. The omniscient god of Jesus knew about the growing pressures under the Indian Ocean during the centuries prior to the disaster. On the morning of the event he observed the Indo-Australian break free and begin to rebound. The omnipotent god of Jesus could have effortlessly dampened the rebound - he chose not to. He watched the wave of less than a metre rise to the surface. The god of Jesus who calmed the storm on Galilee could have quelled the wave and nobody would have known anything about it. No free will would have been infringed in any way. He failed to do so.
The god of Jesus knew that the wave would kill a quarter of a million people and cause suffering and harm millions more. He did nothing.
The god of Jesus did not permit the suffering of the Asian Tsunami - he caused it. He murdered them wilfully, deliberately and with malice aforethought. He made a world that was perfectly designed to kill its inhabitants and passively observed the consequences.
If a man lays landmines around a village and watches children walk across the minefield he is guilty not only of a crime of omission for failing to call a warning but of a deliberate crime of commission.
