"The positions of Bishop Williamson on the Holocaust are absolutely unacceptable and are strongly rejected by the Holy Father," the statement said.

In order to function as a bishop, Williamson must distance himself from his previous statements in "an absolutely unequivocal and public manner," the Vatican said.

In a statement meant to deflect the increasing public outcry over the papal decree lifting the excommunication, the Vatican said the decree did not change the juridical status of the traditionalist Society of St. Pius X, which still has no canonical recognition in the Catholic Church. The society was founded by French Archbishop Marcel Lefebvre, who also incurred automatic excommunication when he ordained the four bishops against papal orders. The society has not accepted the liturgical reforms of the Second Vatican Council and its concepts of religious freedom and ecumenism.

The statement from the Secretariat of State said the society would have to recognize the teachings of Vatican II and of post-conciliar popes to be in full communion. It said the four bishops at present do not have a canonical function in the church and "do not licitly exercise a ministry in the church."

The Vatican has emphasized that even after the removal of the excommunications remaining problems need to be resolved before full communion can be established with the society's leadership and members.

The Secretariat of State statement — like a statement the previous day from the Vatican press spokesman, Jesuit Father Federico Lombardi — reiterated the German-born Pope's remarks at his Jan. 28 audience, in which he recalled the suffering of Jews during the Second World War and said the Holocaust should stand as a "warning to everyone against forgetting, denying or minimizing" evil.

Lombardi said the papal statement at the Jan. 28 audience "could not have been clearer, and from the context it is apparent that it referred to the positions of Bishop Williamson and to all similar positions."

Lombardi's statement was released by the Vatican press office late the same day that German Chancellor Angela Merkel said the Pope and the Vatican needed to make clear there could be no denial of the Holocaust.

On Jan. 21, the same day the Pope lifted the excommunication, a Swedish television station aired a November interview with Williamson in which he repeated his position that the Holocaust had been exaggerated.

The papal decree lifting the excommunication was made public Jan. 24 and Jewish groups — especially in Germany, the United States and Israel — expressed shock that the Vatican would lift the excommunication against Williamson even after his comments had been televised.

German Cardinal Walter Kasper, who co-ordinates the Vatican's dialogue with the Jews, said the controversy was fueled in part by a lack of communication within the Vatican and by "management errors in the Curia."
