For Muslims, Friday Prayer is like Sunday Mass for Christians. It’s the day of community prayer. We travel to our local mosques, our religious sanctuary. Our families gather in the early afternoon to pray as a community. Kids run through the halls as the imam recites the Quran in Arabic. We eat together and mingle outside.

This week, as those of us in the United States attend Friday Prayer, the Muslims in Christchurch, New Zealand, are preparing for funerals.

People around the world are praying for the dead in Christchurch after terrorist attacks at two mosques. The authorities say a 28-year-old Australian walked into two mosques with assault rifles and killed at least 49 people. New Zealand’s prime minister, Jacinda Ardern, called it “an extraordinary and unprecedented act of violence.”

Thoughts and prayers are not enough. These attacks are the latest manifestation of a growing and globalized ideology of white nationalism that must be addressed at its source — which includes the mainstream politicians and media personalities who nurture, promote and excuse it.
