Humor can be offensive and divisive, especially jokes about sensitive issues, such as race and religion. But research is showing religious humor also can have a big upside, one that can help us move past religious stereotypes that divide communities, nations and regions. If humor works, then a key question becomes: Will we choose to laugh together?

Across the world, billions of worshippers this weekend will be going to mosques, temples, churches and other places of worship hearing messages declaring that the choices they make in this life can affect their eternal destiny. How each of them, and secular individuals, face the great existential question of the meaning of life in the face of mortality can make a major difference in areas from mental health to preventing terrorism and promoting more generous, compassionate societies less likely to experience civil strife, new research shows.

We live in an age when a presumed irrevocable gulf between science and religion is perpetuated in the public sphere. But new evidence is emerging that reveals a far more complex picture of the relationship between these powerful social forces. One eight-region study of Religion among Scientists in International Context found a majority of scientists consider themselves either religious or spiritual, or both, in all regions except the United States, United Kingdom and France. However, there is still a lot of work to be done to address long-held animosities. On both sides.

Religion is playing a major role in response to the European economic crisis. As faith-based organizations are increasingly depended upon to meet basic needs, a new landscape of challenges and opportunities is emerging that could result in dramatic shifts in church-state relations. A key question: Can a continent, once seen by many as on an inexorable march toward secularization, create new boundaries between the religious and the secular that respond to social needs in Europe’s increasingly diverse societies?

The global refugee crisis represents a potential transformational moment in world history. Nations from Africa to Asia to Europe to North America with troubled pasts of ethnic conflict and of putting political and economic self-interest above humanitarian needs have an opportunity to write new chapters in their national stories. Religion is playing and will play a critical role.

When it comes to religion and politics in Latin America, a land of increasing political and religious diversity, you can throw many of the Western scripts away. This is not the story of an inexorable march toward secularism, or a descent into holy wars. The paradigm of Latin American religious modernity is rather an evolving dance among political, social and religious forces in a region experiencing the longest democratic process in its history. Pope Francis, women presidents and the rise of Pentecostalism all play a role.

At their best, faith-based organizations and religious communities have embraced Ebola victims with loving care, heedless of their own safety in treating the suffering and working with public health officials in education and prevention efforts. Still, amid the uncertainty that has gripped governments, world health officials and religious groups alike, responses have been varied over religious rituals such as Muslim and traditional African burial practices encouraging the washing of the dead, Christian practices such as exchanging hugs and handshakes and receiving communion orally and the reliance on traditional healers that provide sources of comfort and hope to believers but also pose public health risks.
