WATCH: Father-Son Tag-Team Sermon on Prophetic Grief

On Father's Day — just four days after the shooting at Emanuel A.M.E Church in Charleston, S.C., left nine dead — the Rev. Dr. Otis Moss, Jr., pastor emeritus at Cleveland's Olivet Institutional Baptist Church, and his son, the Rev. Dr. Otis Moss III, Senior Pastor of Trinity United Church of Christ in Chicago, teamed up to preach a remarkable sermon on prophetic grief.

"A few days ago a young man, drunk on the wine of confederate supremacy, high on the ideological opium of racialized thinking, attempted to start a race war," says Otis Moss III in this powerful video.

"This domestic terrorist was unfortunately conceived by America's original sin, and our largest exported product — better known as racism. Many have tried to define this moment as an anomaly, but terror and terrorism come in many forms. We have met Dylann Roof before. ... We have met him before. ... We met him before."

Moss III leads the congregation through America's long, tragic, and irrefutable history of religious violence, immigrant and racial violence, gender violence, and LGBT violence. "Terror is not new, and hatred is a disease that dimenisithed the soul," he says.

This isn't the first time the father-son preachers have tag-teamed a sermon near Father's Day, but it's certainly one of their most powerful. WATCH the sermon below.
