 The genuine Lutherans also claimed to be representatives of the pure doctrine, defenders of orthodoxy, and heirs of the spirit of Martin Luther.Personal, political, and ecclesiastical animosities widened the breach; such as the rivalry between the Ernestine branch of the Saxon house (now extruded from the electoral dignity) and the Albertine branch; the jealousy between the new Ernestine University of Jena and the electoral universities of Wittenberg and Leipzig, in both of which the Philippists had the majority; and the bitter personal antagonism felt at Wittenberg for Flacius, who assailed his former teachers harshly and made all reconciliation impossible.The actual conflict began with the controversy over the Interim and the question of Adiaphora in 1548 and the following years.
