A friend once posed a question about the Apocalypse of Peter - an apocryphal book supposedly written by Peter detailing the rewards of the faithful in heaven and the punishments of the damned in hell. What's interesting about the book is that at the end, the author is told that the damned may be prayed into heaven by the righteous - an idea which challenges the finality of heaven and hell. In addition, the book was widely read and quoted among Christians in the early church. So why is it not a part of our Bible? Here's three quick points regarding problems with the Apocalypse of Peter:
1. Only two manuscripts of this book exist. One manuscript completely omits the "praying the damned into heaven" segment. Thus, the fact that the two copies don't agree on this theological concept makes it questionable, at best.
2. The book goes into extraordinary detail about what heaven and hell are like. In contrast, most descriptions of the hereafter in the Bible are made in only very general terms. For this reason, the subject matter of the Apocalypse of Peter is very enticing (after all, who doesn't want to know more about heaven and hell?) and was probably widely read because it was popular. The unique depictions of heaven and hell also raise questions about the book's authenticity.
3. Whether or not early Christians considered it scriptural does matter - but even that must be taken with a grain of salt. Very simply, theology wasn't a great issue for early believers. While churches today split on matters of doctrine, churches then typically split on matters of discipline. That is, they were more concerned about how a Christian ought to behave than what a Christian ought to believe. Considering the content of the Apocalypse of Peter is largely behavior-focused, it appears to have been written specifically for a 2nd Century Christian viewpoint.
Apopcrypha aside, what exactly does the Bible say about heaven and hell?
"This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."(John 3:19-21 - NIV)
A good illustration of what I mean can be found in Mark Cahill's book, "The One Thing You Can't Do In Heaven". In it, Cahill, a personal friend of Charles Barkley, describes a conversation he had with Barkley's brother, Darryl. During the conversation, Darryl told Cahill that he had recently suffered a heart attack during which he had a near-death experience. Darryl said that during the near-death experience, he remembered floating out of his body, watching momentarily from above as paramedics worked on him and eventually departing toward the "light at the end of the tunnel". Interestingly, he came to find that the "light" was not heaven - it was hell. Darryl was convinced of what he saw and openly admitted to Cahill that he believed he would go to hell when he died. Yet when Cahill pressed Darryl about doing something to correct his fate, Darryl refused. Why? According to Cahill, Darryl simply didn't want to change his lifestyle.
Why would a man who is absolutely certain that hell exists and that he is destined for it do absolutely nothing to save his own soul? The only logical explanation that occurs to me is that for as much as Darryl Barkley does not care to go to hell, he cares even less to seek out God.
Strangely enough, the Bible documents this same idea in the story of Lazarus and the rich man in Luke 16:19-31. There, as the rich man is tormented in hell, he begs Abraham to send Lazarus back from the dead to convince his remaining family to repent before it's too late. Abraham responds, "If they do not listen to Moses and the prophets, they will not be persuaded, even if someone rises from the dead."
I admit it is specualtion and perhaps it's best left that way. The finality and nature of heaven and hell remain difficult topics to fully grasp, though many have tried through the years to put a perspective on it. For further reading, I would recommend C.S. Lewis' book, "The Great Divorce". His insightful views of human nature lend themselves well to the topic at hand and provide some helpful perspectives.
As a parting thought, I'd like to leave you with a quote from C.H. Spurgeon:
If sinners will be damned, at least let them leap to hell over our bodies. And if they perish, let them perish with our arms about their knees, imploring them to stay. If hell must be filled, at least let it be filled in the teeth of our exertions, and let not one go there unwarned or unprayed for.
