Pelagianism views humanity as basically good and morally unaffected by the Fall. It denies the imputation of Adam’s sin, original sin, total depravity, and substitutionary atonement. It simultaneously views man as fundamentally good and in possession of libertarian free will. With regards to salvation, it teaches that man has the ability in and of himself (apart from divine aid) to obey God and earn eternal salvation.
Pelagianism falls away from Christianity in that the works of the person can earn them a spot into salvation instead of the grace of God alone.
I agree that there is a basic goodness in people and they can make morally sound choices. Morality is based on what is acceptable to a society though and I really do not feel that the goodness of a man is a factor into salvation.
