the Feast of Divine Mercy
"Deinde dicit Thomae: infer digitum tuum huc et vide manus meas, et affer manum tuam et mitte in latus meum et noli esse incredulus sed fidelis. Respondit Thomas et dixit ei: Dominus meus et Deus meus!"
"Now 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 shewed 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."
"In the Old Covenant I sent prophets wielding thunderbolts to My people. Today I am sending you with My mercy to the people of the whole world. I do not want to punish aching mankind, but I desire to heal it, pressing it to My Merciful Heart. (1588)
It's a sign for the end times; after it will come the day of justice. While there is still time, let them have recourse to the fount of My mercy; let them profit from the Blood and Water which gushed forth for them. (848)
Before I come as a just Judge, I first open wide the doors of My mercy. He who refuses to pass through the doors of My mercy must pass through the doors of My justice... (1146)"
