You’ve received some very accurate responses to your question TC. I hasten to point out, however, that differing concepts of the Sin of Adam/Ancestral Sin/Original Sin have little to do with dealing with demons at baptism.
Here’s a link to our Baptism rite. You’ll see that Ancestral/Original sin really doesn’t enter into it. but dealing with demons and airy and invisible specters does. We take demons very seriously, TC.

Thank you all for the informative responses. The whole thing is much clearer now! (Everything’s clearer when it’s not 5:30 a.m.)
