Related and contrasting viewpoints of life after death include universal reconciliation, where all souls are immortal (or are mortal, but universally given continuance) and eventually are reconciled, and special salvation, where a positive afterlife is exclusively held by just some souls. Christian mortalism has been taught by several theologians and church organizations throughout history while also facing opposition from aspects of Christian organized religion. The Roman Catholic Church condemned such thinking in the Fifth Council of the Lateran as "erroneous assertions". Supporters include the sixteenth-century religious figure Martin Luther and the eighteenth-century religious figure Henry Layton, among many others.
