"Christians are not voting cattle -- their kingdom isn't of this earth and their king isn't from here," said the petition, also signed by presidents of the Dutch Evangelical and Reformed churches and Archbishop Joris Vercammen of the country's Old Catholic Church.

"You can call this dreamy or dangerous, since Jesus had no message for Caesar. But we will always work for the promised kingdom to be given shape in the country we live in," the petition said.

Dutch Prime Minister Mark Rutte is seeking a third term as head of a government that includes his People's Party for Freedom and Democracy and the Labor Party.

Wilders' Party for Freedom has advocated banning the Quran and closing mosques and Muslim schools, as well as barring immigration from Muslim countries and taking the Netherlands out of the European Union.

Wilders, 53, a nonpracticing Catholic, has vigorously attacked Islam in speeches and urged Dutch Christians to support his program.

The Catholic Church's seven dioceses make up a quarter of the 16.7 million inhabitants of the Netherlands, according to church statistics, although only half a million attend Mass in the country, which was Europe's first to legalize brothels, cannabis, euthanasia and same-sex marriage.

In a pastoral letter published Feb. 28, the bishops' conference urged voters to support parties that "contribute to the common good" by supporting life, families and "the reception of migrants," as well as religious freedom, poverty reduction, and "sustainability and development."

"The spirit of the times seems to have brought a stress on differences and divisions, rather than a search for connectedness and unity -- but let us not indulge in anger, intolerance, indifference and polarization," the bishops said.

"When we stand in the voting booth, we must ask how, in the light of the Gospel, we can contribute to a society based on human dignity, solidarity, fundamental rights, social justice, subsidiarity, tolerance and peace between religions and cultures."
