conservatives of all stripes have a lot more in common than the liberals...
I have far more in common with traditional Roman Catholics, Orthodox Jews, or even patriotic secular conservatives than I have in common with liberals who call themselves Christians.
The problem in this case, however, is that there are strong evangelicals and fundamentalists who seem to have a lower view of the effects of original sin than the Roman Catholic Church.
Politically, we can all agree on most things.
Theologically, we've got a real problem in our own evangelical house that we need to address. It's not good when the official Roman Catholic position has a higher view of the effects of original sin than the views expressed in a document signed by a group of Southern Baptist pastors.
Roman Catholicism is not Pelagianism. We need to give Roman Catholics credit for that.
