I would just like to say that an exclusivism that allows for post-mortem salvation is practically inclusivistic and potentially universalistic.
To those who might comment that the Bible is not open to post-mortem conversion: Yes, it is not open to it, only given the most wooden and tepid reading possible. Otherwise, does it mean anything at all to say that “death is swallowed up in victory” (1 Corinthians 15:54), or to say that “with God all things are possible” (Matthew 19:26)? And what would become of 1 Peter 3:18-21 and 4:6, which speak of Christ’s descent into a spiritual prison and his proclamation of the gospel to “the dead” (1 Peter 4:6)? If by “the dead,” it is only spiritual death that is in mind (doubtful to my mind), does that not still retain the (for the exclusivist) awkward sense that God can reach even the deepest spiritual lifelessness?
This issue is important to me. Because I am tired of seeing it misrepresented, I have chosen to address it briefly here.
