Tonight Fr. David briefly touched upon involuntary sin, the concept of which was baffling to the Roman Catholics in the room - a sin which we do involuntarily? What could that mean? Fr. David emphasized that sin was not the same as culpability or guilt - which would seem to mean that with respect to involuntary sin, "sin" is being used analogically. If that is the case, and involuntary sin is a part of the Greek tradition, can we not say that the use of "sin" analogically is not foreign to the tradition? And that there is room for harmonizing the Latin teaching on original sin with the Greek tradition, on its own terms?
