Catholic Wisdom

"On the day of the Ascension and on the day of Pentecost, there are shadowed forth the ascent of the Lord to Heaven, and the coming of the Holy Ghost down to the Earth. Yet, it is by no means true that, as each of these days comes round, the Lord again ascends to Heaven or the Holy Ghost visibly descends to Earth. But the same cannot be said of the mystery of the Holy Mass, for in it there is made no simple representation of a bygone event, but the self same Sacrifice is unbloodily made which, with the shedding of blood, was made upon the Cross."

--Saint Leonard of Port Maurice, The Hidden Treasure: The Holy Mass.
