McCain said in his March speech, "We must remember that our freedoms are not only defended by our diplomacy and military power but, very importantly, by the decency and respect with which we treat one another."
Parsley says he can be silent no more about Islam. "I will rail against the idea that the God of Christianity and the God of Islam are the same being. I will sound the alarm about the pernicious agenda of the enemies of my country and the cross of my Christ, and I will proclaim the truth at every opportunity."
Parsley, through a spokesperson at his church, declined to be interviewed by ABC News.
In a statement, a spokesperson, Gene Pierce, said Parsley's comments "were in response to militant Islamic leaders' repeated pledges to kill Americans and destroy the United States and Western culture and democracies."
His Web site, said the spokesperson, "also makes a distinction between Muslim terrorists and the vast majority of peaceful Muslims."
Parsley says he has served in the public ministry for more than 30 years and now has a congregation of more than 12,000 people.
He hosts the television show "Breakthrough" on the Trinity Broadcasting Network, aired on 1,400 television and cable channels around the world.
