I'm glad to see this thread resurface; there's quite a bit of interesting commentary going on here. Actually, not having read and reasearched all the roots of early Christianity and the "church fathers," gnostic or not, I can't really evaluate the origins of the Gospels and Christianity historically. However, it's interesting to me to see the sense of two religions, or a religion and a philosophy, being cobbled together to create what we know of today as Christianity.
There seems to be a conflict in Christianity between "what I believe" and "what I know." Some emphasize the teachings of Jesus, the Sermon on the mount, His fulfillment of the law.
The Fulfillment of the Law
17“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. 19Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. 20For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven. (Matt 5)
The emphasis above is on what we do, what we "know" to be the way to the Kingdom in our midst. It was very clear, I think. Jesus taught that we must do as He did, give up everything and follow Him. These are the teachings of Jesus and the emphasis is on His human side.
The other side of the coin is "what we believe."
16“For God so loved the world that he gave his one and only Son,[f] that whoever believes in him shall not perish but have eternal life. 17For God did not send his Son into the world to condemn the world, but to save the world through him. 18Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.[g] (John 3, NIV)
The Gospel of John uses the word "believe" 50 times in the NIV translation (the word apprears 152 times in the entire OT + NT so a full third of the mentions of this word are made in this single Gospel). Believe Jesus is God the Son.
There are the teachings and parables of Jesus, and there is the Passion story. A practical religion, and a mystical religion. A religion of judgement and a religion of grace. A religion of works and a religion of faith. These ideas seem opposed to each other. How do we reconcile them? I think often we are tempted to focus on one and not on the other.
But Jesus was fully God and fully human. I really think those church fathers knew what they were doing when they would not give in to emphasizing just one aspect of Jesus over the other. I think it's brilliant that we have the four Gospels with all their conflicting details and different spins. Paul seems to be more like the Gospel of John, focusing on belief. If you look at James you don't see anything about believing in a resurrected Christ but you get a clear picture of the Way pointed out by Jesus. James is looking at the lifeboat while Paul and the Gospel of John are looking at the ocean.
I wish I could express this more clearly than I know I am doing. Would Christianity have survived as a religion if it didn't have both of these parts? The way to enter the Kingdom is to give up everything, even your life. Everything material, and the richer you are the more you have to let go. Spiritually, you have to die, and rise with Christ. Like in the parable of the rich man,
“With man this is impossible, but not with God; all things are possible with God.” (Mark 10, NIV)
We may dissect the origins of the Gospels and distill the words down to what Jesus may actually have said and weave together the myths that fleshed out the details of Jesus' life, but at the end of the day, what matters? To me it seems that the Spirit is at work in the world, that Person of the Trinity Whom we often seem to overlook, and I believe that not only in spite of, but through whatever mistakes and bumblings and outright power-grabs may have taken place throughout history, the Bible mercifully gives us a Christ who was not just man, not just God, but fully both.
Forgive my late night ramblings!
