No Everlasting Punishment: Hell Not More Than "Explosive" Word, "Dramatic Image"
He explains in his Advent parish bulletin (published on MarkLambert.Blogspot.com) that Christ's mentioning of hell is only a warning to “take care of yourself.”
Christ's usage of “contemporary dramatic images" doesn't refer to "future everlasting punishment," so Fox, and doesn't intend to "cause fear" but only expresses his "deep concern" for human values such as feeding the hungry and loving one another.
