Negotiations between Cardinal William Levada, the head of the Congregation for the Doctrine of Faith and President of the Pontifical Commission Ecclesia Dei (PCED) and Bishop Bernard Fellay, superior of the SSPX have led to nowhere.
After seven years of numerous meetings and discussions, the Vatican has rejected the SSPX's position as "insufficient". The Vatican said that the position of the SSPX “is not enough to overcome the doctrinal problems that are the basis of the fracture between the Holy See and the Society of Saint Pius X".
Last September, the PCED had delivered the SSPX with a Doctrinal preamble in which it indicated what was needed in order to overcome the difficulties with the Catholic Church. In January 2012, the SSPX proposed some amendments to the Vatican, which were then looked over by the Congregation for the Doctrine of Faith and allegedly by Pope Benedict XVI too.
The PCED has given a final deadline of one month for a definitive response by the SSPX.
