Norbert gained adherents in Germany, France, Belgium and Hungary, and houses of his order were founded in Floreffe, Viviers, St-Josse, Ardenne, Cuissy, Laon, Liège, Antwerp, Varlar, Kappenberg, Nagyvárad (Oradea/Großwardein) and elsewhere. Count Theobald II of Champagne wanted to enter the new order, but Norbert counseled him to remain a layman and marry. Norbert prescribed a few rules and invested Theobald with the white scapular of the order, and thus, in 1122, the Third Order of St. Norbert was instituted. He continued to preach throughout France, Belgium and Germany and was successful in combatting a eucharistic heresy in Antwerp proposed by one Tanchelm. In commemoration of this, Norbert has been proclaimed the "Apostle of Antwerp".
