A key difference being that I never once mentioned that humans are inherently good. I think man is flawed and sinned thus needing saving , thus needing mercy and thus needing grace. We are given the free will to repent from our sinful nature and choose Christ our Lord and Saviour who takes away the sin of the world.

The history of the church is filled with as many flaws as anything so I would be careful using the term heresy all Willy nilly without any Biblical references.
