On 11 October 2012, on the occasion of the 50th anniversary of the opening of the Second Vatican Council 60 prominent theologians, (including Hans Küng), put out a Declaration, stating that the intention of Vatican II to balance authority in the Church has not been realised. "Many of the key insights of Vatican II have not at all, or only partially, been implemented . . . A principal source of present-day stagnation lies in misunderstanding and abuse affecting the exercise of authority in our Church."
