I work for the United Methodist Church, and consulting the UMC Book of Discipline, I have to say it expresses almost exactly how I feel about the issue of capital punishment:
“We believe the death penalty denies the power of Christ to redeem, restore, and transform all human beings. The United Methodist Church is deeply concerned about crime throughout the world and the value of any life taken by a murder or homicide. We believe all human life is sacred and created by God and therefore, we must see all human life as significant and valuable. When governments implement the death penalty (capital punishment), then the life of the convicted person is devalued and all possibility of change in that person's life ends. We believe in the resurrection of Jesus Christ and that the possibility of reconciliation with Christ comes through repentance. This gift of reconciliation is offered to all individuals without exception and gives all life new dignity and sacredness. For this reason, we oppose the death penalty (capital punishment) and urge its elimination from all criminal codes.” From The Book of Discipline of the United Methodist Church – 2008, pg. 125-26.
