Once Saved Always Saved???

David Bercot, editor of this dictionary, also wrote a provocative book called, Will the Real Heretics Please Stand Up? It takes today’s Evangelical Church, both its lifestyle and teaching, and looks at it in the light of early Christian teaching. It is an interesting book that comes from someone who has read through the entire works of the Ante-Nicene Fathers more than once. He writes,
Since the early Christians believed that our continued faith and obedience are necessary for salvation, it naturally follows that they believed that a “saved” person could still end up being lost. For example, Irenaeus, the pupil of Polycarp, wrote, “Christ will not die again on behalf of those who now commit sin because death shall no more have dominion over Him…. Therefore we should not be puffed up…. But we should beware lest somehow, after [we have come to] the knowledge of Christ, if we do things displeasing to God, we obtain no further forgiveness of sins but rather be shut out from His kingdom” (Heb. 6:4-6) [p. 65].
