In February 2011, Bishop Bernard Fellay, said that reconciliation talks with the Vatican would soon be coming to an end, with little change in the views of either side. In addition to disputes over the changes introduced by the Second Vatican Council, new problems had been created by plans to beatify Pope John Paul II on 1 May 2011, which, he said, posed "a serious problem, the problem of a pontificate that caused things to proceed by leaps and bounds in the wrong direction, along 'progressive' lines, toward everything that they call 'the spirit of Vatican II.'"
