Jean II Restout, c. 1732
Today the Church celebrates the Feast of Pentecost when Holy Spirit descends on Mary, the Apostles, and other disciples of Jesus, just as He promised before His Ascension.
So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?” He said to them, “It is not for you to know times or seasons which the Father has fixed by his own authority. But you shall receive power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Samar′ia and to the end of the earth.” And when he had said this, as they were looking on, he was lifted up, and a cloud took him out of their sight. Acts 1:6-9 (emphasis added)
Jesus’ promise of the Holy Spirit was not just for His Apostles and disciples in the Upper Room. He continues to pour out His Spirit upon us and His Church today. He is also sending us out on mission to preach the Gospel of His saving work on the cross. He has equipped us with the Holy Spirit who will guide us in all knowledge and truth; “the Counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things” (Jn 14:26).
