the Apostles and disciples spoke of the Holy Ghost on and after
the day of Pentecost, if they did not know Him? Immediately after
the fiery baptism, with its blessed filling, Peter stood before
the people, and said: "This is that which was spoken by the
prophet Joel: And it shall come to pass in the last days, saith
God, I will pour out My Spirit upon all flesh"; then he exhorted
the people and assured them that if they would meet certain

emotion, but) "with the Holy Ghost." Certainly they must have
known Him. And if they knew Him, may not we?

Paul says: "Now we have received, not the spirit of the world,

"that every real Christian can say, with the Marquis de Renty, 'I
