Columbus will host a summit of two religions this weekend. The event called "Catholics and Sikhs Together: Bringing Compassion to the World" is organized by U.S. Conference of Catholic Bishops and the American Region of the World Sikh Council. It is designed to increase understanding and build friendships through intellectual exchanges. The event will be at the St. Therese Retreat Center on the East side. It's the second time Columbus has hosted the event, and is the fifth held overall since 2006.
