It's too bad you see it necessary to frame the discussion of Confession=Communion within the tension between "Traditionalist" and "Modernist" Orthodoxies.
You got me wondering why in the world those of us who are super-traditionalists are accused of being modernists? It seems to me that the issue is between two camps:
Ladies and gents, on this corner are the Super Orthodox--those who are convinced that everything that they have received and currently believe/do must not change because the latest is the bestest (just like Muslims believe: Mohamed was last so he trumps all others before him).
And, on this corner are The Back to the Future gang--those who try to preserve and promulgate the best of Orthodoxy, even if this means a change or two BUT ALWAYS back to a practice of the past.
I don't know about you but I think that the traditionalism of the first group is a shallow brook, while the traditionalism of the second group is a river that runs deep, clear and true.
