Did I or anyone respond to this?
There may be some popular sentiment like you describe, but the teaching is that original sin is not personal sin and is washed away at baptism. A baptized Christian does not bear the sin of Adam in any sense, although, just like the Orthodox believe, he struggles with the inherited consequences of that sin.
I was referring to Calvinists, who cliam that this is the teaching of St. Augustine. I am fully aware that the Catholic Church does not subscribe this doctrine of theirs. Which is why we (catholic Christians) are often labeled "semi-Pelagian."
