An American Cardinal is speaking up about the patriotic duty of majority Christian countries to impose limits on Muslim migration, seemingly contradicting Pope Francis’ “welcome the stranger” philosophy.

U.S. Cardinal Raymond Burke attended a pro-life, pro-family conference in Rome last Friday ahead of the country’s March for Life when he responded to a written question from a conference participant about Muslims flooding into Christian nations, according to the National Catholic Reporter.

Burke said “to resist large-scale Muslim immigration in my judgement is to be responsible.”

The reason, he said, is because Islam “believes itself to be destined to rule the world.”

“You don’t have to be a rocket scientist to see what has happened in Europe,” Burke said, pointing to France, Germany and Italy.

The problems stem from Muslims taking advantage of the unwillingness of Christian nations to stand behind moral norms and cultural traditions, he said.

“Muslims have said that they are able today to accomplish what they were not able to accomplish in the past with armaments because Christians are no longer ready to defend their faith, what they believe,” Burke said. “they are no longer ready to defend the moral law.”

While Christians should help “individuals that are not able to find a way of living in their own country,” many Muslim migrants “are opportunists” taking advantage of the generosity, he said.

The 70-year-old Cardinal contends Catholics should help the migrants understand “what is bankrupt in the culture” and work with them and others “to recover what is true culture,” which Burke identified as the dignity of life, respect for sexual morality and worshiping God, according to the Reporter.

Resisting “large-scale Muslim immigration is in fact, as far as I’m concerned, a responsible exercise of one’s patriotism,” Burke said.

The comments stand in stark contrast to the pontificates of Pope Francis, who has repeatedly criticized President Donald Trump’s proposed border wall and opposition to Muslim migration in Europe.

“The issue of migration has never been resolved by raising barriers, fomenting fear of others or denying assistance to those who legitimately aspire to a better life for themselves and their families,” Francis said as he met with Muslim leaders in Morocco in March.

“Builders of walls, be they made of razor wire or bricks, will end up becoming prisoners of the walls they build,” he said.

According to the Associated Press report:

Later Saturday, Francis repeated the sentiment during an encounter with migrants from Nigeria, Guinea, Cameroon and other countries, telling them they deserved to be welcomed, protected and integrated into their new homes. He called for expanded legal channels for migration and for protections for the most vulnerable, regardless of their refugee status.

The Pope argued its Muslims flooding into Christian countries that are being exploited, not the other way around, he argued.

“This shared commitment is needed in order to avoid presenting new opportunities for those merchants of the human flesh who exploit the dreams and needs of migrants,” he said.
