From the Acts of the Apostles, 2:1-11: And when the days of the Pentecost were accomplished, they were all together in one place: And suddenly there came a sound from heaven, as of a mighty wind coming, and it filled the whole house where they were sitting. And there appeared to them parted tongues as it were of fire, and it sat upon every one of them: And they were all filled with the Holy Ghost, and they began to speak with divers tongues, according as the Holy Ghost gave them to speak. Now there were dwelling at Jerusalem, Jews, devout men, out of every nation under heaven.
And when this was noised abroad, the multitude came together, and were confounded in mind, because that every man heard them speak in his own tongue. And they were all amazed, and wondered, saying: Behold, are not all these, that speak, Galileans? And how have we heard, every man our own tongue wherein we were born? Parthians, and Medes, and Elamites, and inhabitants of Mesopotamia, Judea, and Cappadocia, Pontus and Asia, Phrygia, and Pamphylia, Egypt, and the parts of Libya about Cyrene, and strangers of Rome, Jews also, and proselytes, Cretes, and Arabians: we have heard them speak in our own tongues the wonderful works of God.
Continuation of the Holy Gospel according to St. John: At that time, Jesus said to his disciples: If any one love me, he will keep my word, and my Father will love him, and we will come to him, and will make our abode with him. He that loveth me not, keepeth not my words. And the word which you have heard, is not mine; but the Father' s who sent me. These things have I spoken to you, abiding with you. But the Paraclete, the Holy Ghost, whom the Father will send in my name, he will teach you all things, and bring all things to your mind, whatsoever I shall have said to you. Peace I leave with you, my peace I give unto you: not as the world giveth, do I give unto you. Let not your heart be troubled, nor let it be afraid. You have heard that I said to you: I go away, and I come unto you. If you loved me, you would indeed be glad, because I go to the Father: for the Father is greater than I. And now I have told you before it comes to pass: that when it shall come to pass, you may believe. I will not now speak many things with you. For the prince of this world cometh, and in me he hath not any thing. But that the world may know, that I love the Father: and as the Father hath given me commandment, so do I: Arise, let us go hence.
