Gnosticism, a heresy rampant during the early church, said salvation was only available to those who possessed the hidden truths of Christ. Bultmann espouses a kind of neo-gnosticism, a wholly subjective encounter with Jesus, which is the basis for many people’s professed Christianity. A personal encounter with Jesus is necessary, but we do not believe simply because He “lives in our heart” (1 Cor. 3:16). We believe because He truly came, truly died, and truly rose again.
