The number of Israeli Catholics of non-Arab origin increased during the 1990s, due primarily to immigration from the former Soviet Union. As a result, the Vatican changed its policies in 2003, for the first time ordaining Jean-Baptiste Gourion as Auxiliary Bishop to overlook the Hebrew Catholic community in Israel. The appointment of David Neuhaus as vicar upon Gourion's death in 2003, however, is not in conformity with the importance that the Holy See ostensibly attributes to the newly emerging community. On the other hand, Neuhaus did participate in the Synod for Middle Eastern clergy as a special invitee of the Pope, and Hebrew – for the first time ever – was one of the official languages in which Radio Vatican covered the event.
