Genesis is not fact, there for Jesus is not necessary?

[Neo-Scholastic]

Original sin first appeared with Augustine and was adopted by the Church of Rome and later incorporated into the Reformed churches. For most denominations, original sin is a central doctrine. That said, I do not think the doctrine (with which I disagree by the way) does not require decent from a single set of parents, i.e. Adam and Eve., as demanded by Evangelicals. As an allegory, it describes the human condition, our state prior to acceptance of Christ’s saving work.

I don't have time right now, but I'm sure you'll want to know about the Gospel genealogies.
