Yes......and by the spiteful, jealous, underhanded Joseph Ratzinger.  Kung and the other hundred-plus theologians silenced (well, sort of - many were hired as professors anyways) were all pawns in +Ratzinger's attempts to make himself the sole voce of Catholic teaching.  Now he is just a ghost walking in the papal gardens, unable to hurt anyone further.  I wonder (perhaps you have a news flash for us Marty?) how many of his opinions have changed since he move down the lane from the Apostolic Palace?
