 The committee drafted a vague formula which could be interpreted in a Catholic or a Calvinistic sense, and was consequently condemned by both parties.The assemblage of prelates refused assent, and the Calvinists would not commit themselves to the Lutheran Confession.Subsequently there were meetings at Altenburg (20 October 1568 – 9 March 1569) between the Jena theologians and those from Wittenberg, on free will and justification; and at Montbéliard (1586) between Beza and the Tübingen theologians, on predestination.
