And now a quote from von Hildebrand:
To deplore disunity as such, instead of deploring heresies, instead of condemning these and calling them by their name, implies first of all that one would keep unity even at the cost of truth. But, of course, true unity presupposes unity in truth. Error, falsehood, can never be the basis for true unity....If we are truly concerned for unity among Christians, I submit that there is only one way to restore it, and it is the time-honored way: the anathema against all heretics. This is the way the Church has survived, kept her identity, through all centuries...True unity can be restored only by the conversion of the heretic -- or at least his submission -- or by his excommunication.And here's a message from Jeff Mirus of Catholic Culture suggesting the proper response is to immediately defrock this heretical priest. I second it!
