Vatican City, Sep 20, 2018 / 05:21 pm (CNA/EWTN News).- All people have a responsibility to fight new forms of racism in the modern world, Pope Francis told more than 200 participants at a Rome-based conference this week.

“We are living in times in which feelings that many thought had passed are taking new life and spreading,” the pope said Sept. 20.

The international conference on “Xenophobia, Racism and Populist Nationalism in the Context of Global Migration” concluded Thursday. It had been promoted by the Vatican's Dicastery for Integral Human Development, the World Council of Churches and the Pontifical Council for the Promotion of Christian Unity.

Addressing those present, Pope Francis warned that the modern world appears to be seeing an increase in “feelings of suspicion, fear, contempt and even hatred towards individuals or groups judged for their ethnic, national or religious identity.”

These individuals are “considered not sufficiently worthy of being fully part of society's life,” and such sentiments “all too often inspire real acts of intolerance, discrimination or exclusion,” he said.

Exclusion of foreigners can also become enshrined in political policy, as some lawmakers exploit fears and misgivings for political gain, he said.

Faced with these social changes, “we are all called, in our respective roles, to cultivate and promote respect for the intrinsic dignity of every human person,” the pope said.

He emphasized the role of religious leaders, educators, and media in this endeavor to promote a culture that respects human life and dignity.

Rev. Olav Fykse Tveit, secretary general of the World Council of Churches, told Vatican News that the conference was intended to show a strong ecumenical commitment to addressing the global issues of racism and xenophobia, to hear from voices across the globe about the issue, and to create common text that can be used as the basis of further efforts.

He stressed the importance of supporting politicians who are standing up for the human rights of migrants, and emphasized the role of religious leaders in upholding human dignity in public discussions surrounding migration.

“There is no easy political answer to all of this: it is a very complex political situation, but we believe that the churches, with our values but also with our networks, our communities, as human beings and as people of faith, can contribute a lot,” he said.
