By His glorious Resurrection from the dead the Sacred Body of Christ has again been re-united with the Precious Blood. The Eucharistic Christ we receive is the living Lamb of God. He departed from them, and was carried up to heaven. And they adoring went back into Jerusalem with great joy. Thus, with every final blessing we are drawn into the mystery of Our Lord's Ascension.
Devotion nurtures theological faith.
We are not taking flights of pious fancy in an exercise such as this. Our limited intelligence cannot grasp infinite things, and so we necessarily make use of the imagination, in order to cooperate with the Holy Ghost's work on our souls. The Mass is the mystical Life of Christ and we are members of the Mystical Body of Christ. It only stands to reason, that if we are members of His Body then we must learn how to participate in His Life until we rest safely with the Beatific Vision.
