"The Pope's statement is part of a conspiracy to pit the world's religions against each other,' said Sahibzada Fazal Karim, a member of Pakistan's parliament and the leader of Sunni Ittehad, an alliance of eight Sunni Muslim groups, according to Pakistani newspaper Dawn News.
Speaking on Monday during an address to diplomats accredited to the Holy See, Benedict called on governments to do more to protect Christians who have recently been the victims of violence in Egypt, Nigeria and Iraq.
He also called for the abolition of a law in Pakistan which cited last week's assassination of the Punjab governor Salman Taseer who called supported a Christian woman on awaiting execution for under the blasphemy law.
"I once more encourage the leaders of that country to take the necessary steps to abrogate that law, all the more so because it is clear that it serves as a pretext for acts of injustice and violence against religious minorities," Benedict said.
Karim called the pope's comments a "violation of the UN's charter of peace," saying they meddled in a sovereign country's internal affairs.
Taseer's security guard Malik Mumtaz Qadr has admitted to the assassination.
