Since the Ascension God's plan has entered into its fulfilment. We are already at "the last hour". "Already the final age of the world is with us, and the renewal of the world is irrevocably under way; it is even now anticipated in a certain real way, for the Church on earth is endowed already with a sanctity that is real but imperfect." Christ's kingdom already manifests its presence through the miraculous signs that attend its proclamation by the Church.
