The disciples receive the Holy Ghost. Peter’s sermon to the people. The piety of the first converts.
 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.
 I say then, walk in the spirit, and you shall not fulfill the lusts of the flesh.  For the flesh lusteth against the spirit: and the spirit against the flesh; for these are contrary one to another: so that you do not the things that you would.  But if you are led by the spirit, you are not under the law.  Now the works of the flesh are manifest, which are fornication, uncleanness, immodesty, luxury,  Idolatry, witchcrafts, enmities, contentions, emulations, wraths, quarrels, dissensions, sects,
 Envies, murders, drunkenness, revellings, and such like. Of the which I foretell you, as I have foretold to you, that they who do such things shall not obtain the kingdom of God.  But the fruit of the Spirit is, charity, joy, peace, patience, benignity, goodness, longanimity,  Mildness, faith, modesty, continency, chastity. Against such there is no law.  And they that are Christ’s, have crucified their flesh, with the vices and concupiscences.  If we live in the Spirit, let us also walk in the Spirit.
John 15:26-27; 16:12-15
 But when the Paraclete cometh, whom I will send you from the Father, the Spirit of truth, who proceedeth from the Father, he shall give testimony of me.  And you shall give testimony, because you are with me from the beginning.
 I have yet many things to say to you: but you cannot bear them now.  But when he, the Spirit of truth, is come, he will teach you all truth. For he shall not speak of himself; but what things soever he shall hear, he shall speak; and the things that are to come, he shall shew you.  He shall glorify me; because he shall receive of mine, and shall shew it to you.  All things whatsoever the Father hath, are mine. Therefore I said, that he shall receive of mine, and shew it to you.
