Mennonites generally don’t spend a lot of time debating or depicting punishment in the afterlife. The Confession of Faith in a Mennonite Perspective states: “At Christ’s glorious coming again for judgment . . . the righteous will rise to eternal life with God, and the unrighteous to hell and separation from God.”
This is probably the closest description of heaven or hell to be found in any sort of church-wide statement: that heaven is eternal life with God, and hell is eternal separation from God.
