An Attack Against G-d

Vatican Cardinal Jose Saraiva Martins called the death of Terri Schiavo, "An attack against G-d," as opposed to the misdemeanors committed by the Chruch throughout its history, such as the Crusades, the Inquisition, and the wars against the Reformation.

As Stalin once famously said, "One death is a tragedy; a million is a statistic." And hence, the Church is only responsible for statistics.

Lots of statistics.

Therefore, it has the moral authority to pass judgment in this case.
