And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. And they were all amazed and marvelled saying one to another, Behold, are not all these which speak Galilaeans? And how hear we every man in our own tongue, wherein we were born? Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God.
Prayer for the Indwelling of the Spirit
by Saint Augustine
Holy Spirit, powerful Consoler,
sacred Bond of the Father and the Son,
Hope of the afflicted,
descend into my heart and establish
in it your loving dominion.
Enkindle in my tepid soul
the fire of your Love
so that I may be wholly subject to you.
We believe that when you dwell in us,
you also prepare a dwelling for
the Father and the Son.
Deign, therefore, to come to me,
Consoler of abandoned souls,
and Protector of the needy.
Help the afflicted, strengthen the weak,
and support the wavering.
Come and purify me.
Let no evil desire take possession of me.
You love the humble and resist the proud.
Come to me, glory of the living,
and hope of the dying.
Lead me by your grace that I may
always be pleasing to you.
