1 Corinthians 15:17-20: "17 And if Christ has not been raised, your faith is futile and you are still in your sins. 18 Then those also who have fallen asleep in Christ have perished. 19 If in Christ we have hope in this life only, we are of all people most to be pitied.
"20 But in fact Christ has been raised from the dead, the firstfruits of those who have fallen asleep."
Mark 16:1-8: "1 When the Sabbath was past, Mary Magdalene and Mary the mother of James and Salome bought spices, so that they might go and anoint him. 2 And very early on the first day of the week, when the sun had risen, they went to the tomb. 3 And they were saying to one another, 'Who will roll away the stone for us from the entrance of the tomb?' 4 And looking up, they saw that the stone had been rolled back - it was very large. 5 And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe, and they were alarmed. 6 And he said to them, 'Do not be alarmed. You seek Jesus of Nazareth, who was crucified. He has risen; he is not here. See the place where they laid him. 7 But go, tell his disciples and Peter that he is going before you to Galilee. There you will see him, just as he told you.' 8 And they went out and fled from the tomb, for trembling and astonishment had seized them, and they said nothing to anyone, for they were afraid."

Christians, to the Paschal Victim
Offer your thankful praises!
The Lamb the sheep has ransomed:
Christ, who only is sinless,
Reconciling sinners to the Father.
Death and life have contended
In that combat stupendous:
The Prince of life, who died,
Reigns immortal.
"Speak, Mary, declaring
What you saw when wayfaring."
"The tomb of Christ, who is living,
The glory of Jesus' resurrection;
Bright angels attesting,
The shroud and napkin resting.
My Lord, my hope, is arisen;
To Galilee He goes before you."
Christ indeed from death is risen,
Our new life obtaining.
Have mercy, victor King, ever reigning!
Amen. Alleluia.

The text from 1 Corinthians appears in the last verse. "Christ indeed from death is risen" is a paraphrase of "But in fact Christ has been raised from the dead."
The second verse is from the text from Mark.
"The Lamb the sheep has ransomed" in the first verse seems to draw from John 1:29: "The next day he [John the Baptist] saw Jesus coming toward him, and said, 'Behold, the Lamb of God, who takes away the sin of the world!'"
