This is lecture 3 in my course on Presbyterian History and Reformed Confessions, which guides students through the history and theology of the PCUSA's Book of Confessions.
If you watch my lectures you'll see that I interpret the Reformed tradition in precisely the opposite way that you do. I have no interest in "keeping the heritage" alive, as if this tradition is in itself something to preserve. The tradition is only a witness to a reality that is utterly beyond it, and much that is historically Reformed ought to burn like so much chaff. If nothing else, I hope my lectures hasten the necessary burning that is long overdue.
