Regal Books author Richard Twiss died Saturday of complications following a heart attack while he was in Washington, D.C., for the National Prayer Breakfast. He was 58.
The co-founder and president of Wiconi International, an organization that aims toward reconciliation between Native Americans and other Americans, was a columnist for Charisma magazine, a Christianity Today magazine contributor, and author of One Church, Many Tribes, published by Gospel Light in 2000.
In a statement, Gospel Light/Regal Books officials said: "Richard was a gentle man with a clear vision and calling, which was stated best in his book, 'Unless all the various parts that God designed to make up the whole are intact and functioning, there is dysfunction. Each and every part must be connected and engaged, or there is no possible way for the whole to function fully and according to God's design and best plan.' "
Twiss was a member of the Sicangu Lakota Oyate people from the Rosebud Sioux Reservation in South Dakota. Twiss is survived by his wife, Katherine, and four sons, Andrew, Phillip, Ian and Daniel-Emmett.
