As mentioned in another thread, the Bible itself has changed a great deal from the Aleppo Bible, the most complete of the older Bibles, written 1100 years ago. And the faith, of course, has changed a great deal as well. Arius and his followers were anathamized when they refused to accept that Jesus was divine and the son of God. Their position was quite popular, in fact, most of the early Christians did not believe that Jesus was the only begotten son of God or an equal member of the trinity. But Emperor Constantine decided that divinity was necessary in order to strengthen the church, so he "coerced" many bishops into signing the Nicene Creed, even those who had supported Arius and the teachings of the early church. They would have had a huge problem with the emperor if they had not signed. Arius himself was anathemized and banished from the land, losing a great deal of his wealth, because of his convictions. Other bishops merely took the easy way out, and therefore, the "divinity" of Christ was established, as well as the fact that he was God's son. Some other things also came out of the Council of Nicaea.
So, the church has changed all along and must continue to change if it is to survive. Christianity Today, a Christian magazine, wrote in an article in November of 2009 that, if the decline in Christian membership continues, then as many as 80 percent of young people born today (2009) will leave the church by the age of 29. That's a huge percentage. Traditionally, teens used to leave the church and then return when they had families to raise up in a faith. That's not happening as it used to. People are staying away. This is one of the reasons the churches introduced rock music, in order to lure the kids back. It worked, but the music is not holding the kids. The underlying inconsistencies in the Bible and the early faith are turning them away.
The young people are doing something that a lot of the older folks didn't do: they are actually reading the Bible, and they don't like what they read. While older people often just read their favorite parts over and over, these kids are reading the parts that give them qualms, and they are turning away. If the church does not acknowledge the fact that the bible, or at least much of it, is fiction, they will not hold the kids. Kids don't want a God who would actually condone genocide, prejudice, the subjugation of women, etc. They would accept it if the church leaders admitted that many parts where "The lord saith" this or that, were simply written by prejudiced men who wanted their people to follow them. They won't accept being told that those were actually god's words.
In other words, the Christian faith must stop telling people that they must either believe in the Bible or go to hell. If they cling to their fire and brimstone, empty threats, they will surely die. And that actually would be a shame, because there is such a richness to the myths/history/legends of the Bible. I hope the faith endures.
