Mr Bush added: "In a world where some no longer believe that we can distinguish between simple right and wrong, we need your message to reject this dictatorship of relativism."
Supreme court clears way for executions to resume:
The Supreme Court on Wednesday rejected a challenge to the lethal three-drug cocktail used in most U.S. executions, clearing the way for a resumption of executions halted since last September.
By a 7-2 vote, the high court rejected a challenge by two Kentucky death row inmates who argued the current lethal injection method violated the constitutional ban on cruel and unusual punishment by inflicting needless pain and suffering.
"We too agree that petitioners have not carried their burden of showing that the risk of pain from maladministration of a concededly humane lethal injection protocol, and the failure to adopt untried and untested alternatives, constitute cruel and unusual punishment," Chief Justice John Roberts wrote in the court's main opinion.
The Supreme Court's decision was announced as Pope Benedict, an opponent of the death penalty, visited President George W. Bush at the White House.
If the answer to the question "Is killing people wrong?" is "It depends," isn't that moral relativism?
