According to The Telegraph:
Acts such as showering the Princess’s hearse with flowers show that the public is reverting to a “Catholic” approach to death after centuries of protestant reserve, the Archbishop of Westminster, the Most Rev Vincent Nichols suggested.
He said that the Princess’s funeral in 1997 marked a watershed in British history and would be remembered as the “end of the Reformation in England”.
Catholic practices such as prayers for the souls of the dead and a belief in saints, which were dismissed by protestant reformers in the 16th Century, are now being rediscovered, he said.
