God and the problem of sincere disbelief

[SingingAnalyst]

As a Christian (though not a fundamentalist), I do not think believing in G-d is essential to morality. At one time my Christian experience and beliefs were fundamentalist; not any more. What I have learned is: (1) one can disbelieve any aspect of the Christian theological or even ethical system, and it does not make one immoral; and (2) morality is often confused with unselfishness.  The elements of Christianity I have retained are (1) a belief in the benefit of forgiveness (within reason) for all parties involved and (2) a disposition to side with the underdog, or with one who is being unfairly attacked.
