On the evening of that day, the first day of the week, the doors being shut where the disciples were for fear of the Jews, Jesus came and stood among them and said to them: "Peace be with you." When He had said this, He showed them His hands and His side. Then the disciples were glad when they saw the Lord. Jesus said to them again, "Peace be with you. As the Father has sent me, even so I send you." And when He had said this, He breathed on them, and said to them: "Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained."
Now Thomas, one of the twelve, called the Twin, was not with them when Jesus came. So the other disciples told him: "We have seen the Lord." But he said to them: "Unless I see in His hands the print of the nails, and place my finger in the mark of the nails, and place my hand in His side, I will not believe."
Eight days later, His disciples were again in the house, and Thomas was with them. The doors were shut, but Jesus came and stood among them, and said: "Peace be with you." Then He said to Thomas, "Put your finger here, and see my hands; and put out your hand, and place it in my side; do not be faithless, but believing." Thomas answered Him, "My Lord and my God!" Jesus said to Him: "Have you believed because you have seen me? Blessed are those who have not seen and yet believe."
Now Jesus did many other signs in the presence of the 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.
ABOUT THAT TIME, Herod the king laid violent hands upon some who belonged to the church. He killed James the brother of John with the sword; and when he saw that it pleased the Jews, he proceeded to arrest Peter also. This was during the days of Unleavened Bread. And when he had seized him, he put him in prison, and delivered him to four squads of soldiers to guard him, intending after the Passover to bring him out to the people. So Peter was kept in prison; but earnest prayer for him was made to God by the Church.
The very night when Herod was about to bring him out, Peter was sleeping between two soldiers, bound with two chains, and sentries before the door were guarding the prison; and behold, an angel of the Lord appeared, and a light shone in the cell; and he struck Peter on the side and woke him, saying, "Get up quickly." And the chains fell off his hands. And the angel said to him, "Wrap your mantle around you and follow me." And he went out and followed him; he did not know that what was done by the angel was real, but thought he was seeing a vision. When they had passed the first and the second guard, they came to the iron gate leading into the city. It opened to them of its own accord, and they went out and passed on through one street; and immediately the angel left him. And Peter came to himself, and said, "Now I am sure that the Lord has sent his angel and rescued me from the hand of Herod and from all that the Jewish people were expecting."
Though the doors were shut at the dwelling where the disciples were gathered for fear of the Jews on the evening of the Sunday after the Passover, our Saviour wondrously entered and stood in their midst, and greeted them with His customary words, "Peace be unto you." Then He showed unto them His hands and feet and side; furthermore, in their presence, He took some fish and a honeycomb and ate before them, and thus assured them of His bodily Resurrection. But Thomas, who was not then present with the others, did not believe their testimony concerning Christ's Resurrection, but said in a decisive manner, "Except I shall see in His hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into His side, I will not believe." Wherefore after eight days, that is, on this day, when the disciples were again gathered together and Thomas was with them, the Lord Jesus came while the doors were shut, as He did formerly. Standing in their midst, He said, "Peace be unto you"; then He said to Thomas, "Bring hither thy finger, and behold my hands; and bring hither thy hand, and thrust it into My side: and be not unbelieving, but believing."
And Thomas, beholding and examining carefully the hands and side of the Master, cried out with faith, "My Lord and my God." Thus he clearly proclaimed the two natures - human and divine - of the God-man (Luke 24:36-49; John 20:19-29).
This day is called Antipascha (meaning "in the stead of Pascha," not "in opposition to Pascha") because with this day, the first Sunday after Pascha, the Church consecrates every Sunday of the year to the commemoration of Pascha, that is, the Resurrection.
