INTROIT (I Peter, 2. 2)
AS NEWBORN babes, alleluia, desire the rational milk without guile, alleluia, alleluia, alleluia. Ps. 80. 2. Rejoice to God our Helper; sing aloud to the God of Jacob. ℣. Glory be to the Father, and to the Son, and to the Holy Ghost. As it was in the beginning, is now, and ever shall be, world without end. Amen.—As newborn babes…
GRANT, we beseech Thee, almighty God, that we who have celebrated the Paschal Feast, may, by Thy bounty, retain its fruits in our daily habits and behavior. Through our Lord Jesus Christ, Thy Son, who with Thee liveth and reigneth in the unity of the Holy Ghost, God, world without end.
EPISTLE (From the First Letter of Blessed John the Apostle, 5. 4-10.)
DEARLY beloved: Whatsoever is born of God overcometh the world: and this is the victory, which overcometh the world, our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God? This is He that came by water and blood, Jesus Christ: not by water only, but by water and blood. And it is the Spirit which testifieth that Christ is the truth. And there are three who give testimony in heaven: the Father, the Word and the Holy Ghost: and these three are one. And there are three that give testimony on earth: the Spirit and the water and the blood; and these three are one. If we receive the testimony of men, the testimony of God is greater: for this is the testimony of God, which is greater, because He hath testified of His Son. He that believeth in the Son of God hath the testimony of God in himself.
Alleluia, alleluia. (Matth. 28. 7.) On the day of My Resurrection, saith the Lord, I will go before you into Galilee. Alleluia. (John 20. 26.) After eight days, the doors being shut, Jesus stood in the midst of His disciples and said: Peace be to you. Alleluia.
GOSPEL (Continuation of the holy Gospel according to St. John, 20. 19-31.)
AT THAT TIME, when it was late that same day, the first of the week, and the doors were shut, where the disciples were gathered together for fear of the Jews, Jesus came, and stood in the midst and said to them: Peace be to you. And when He had said this, He showed them His hands and His side. The disciples therefore were glad, when they saw the Lord. He said therefore to them again: Peace be to you. As the Father hath sent me, I also send you. When He had said this, He breathed on them, and He said to them: Receive ye the Holy Ghost: whose sins you shall forgive, they are forgiven them: and whose sins you shall retain, they are retained. Now Thomas, one of the twelve, who is called Didymus, was not with them when Jesus came. The other disciples therefore said to him: We have seen the Lord. But he said to them: Except I shall see in His hands the print of the nails, and put my finger into the place of the nails, and put my hand into His side, I will not believe. And after eight days, again His disciples were within, and Thomas with them. Jesus cometh, the doors being shut, and stood in the midst, and said: Peace be to you. Then He saith to Thomas: Put in thy finger hither, and see My hands, and bring hither thy hand, and put it into My side; and be not faithless, but believing. Thomas answered and said to Him: My Lord and my God. Jesus saith to him: Because thou hast seen Me, Thomas, thou hast believed; blessed are they that have not seen, and have believed. Many other signs also did Jesus in the sight of His disciples, which are not written in this book. But these are written, that you may believe that Jesus is the Christ, the Son of God; and that, believing, you may have life in His Name. — Creed.
OFFERTORY (Matth. 28. 2, 5, 6)
AN ANGEL of the Lord descended from heaven, and said to the women: He whom you seek is risen, as He said, alleluia.
RECEIVE, we beseech Thee, O Lord, the gifts of Thine exultant Church: and to whom Thou has given cause for so great joy, grant the fruit of perpetual happiness. Through our Lord Jesus Christ …
PREFACE FOR EASTER
IT is truly meet and just, right and for our salvation, at all times to praise Thee, O Lord, but more gloriously (especially this day) when Christ our Pasch was sacrificed. For He is the true Lamb Who took away the sins of the world: Who by dying destroyed our death, and by rising again hath restored us to life. And therefore with Angels and Archangels, with Thrones and Dominations, and with all the hosts of the heavenly army, we sing a hymn to Thy glory, evermore saying: — Sanctus.
COMMUNION (John 20. 27)
PUT in thy hand, and know the place of the nails, alleluia; and be not faithless, but believing, alleluia, alleluia.
We beg Thee, O Lord our God, that these sacred and holy mysteries which Thou hast given us to safeguard our rebirth, may be for us a remedy both now and in the future. Through our Lord Jesus Christ Thy Son …
