The third Sunday after Pascha is dedicated to the myrrhbearing women who cared for the body of the Saviour at his death and who were the first witnesses of His Resurrection. The three troparia of Holy Friday are sung once again and from the theme of the day:
The noble Joseph, when he had taken down Thy most pure body from the Tree, wrapped it in fine linen and anointed it with spices, and placed it in a new tomb.
When Thou didst descend to death, O Life Immortal, Thou didst slay hell with the splendor of Thy Godhead.
The angel came to the myrrhbearing women at the tomb and said: Myrrh is fitting for the dead, but Christ has shown Himself a stranger to corruption! So proclaim: The Lord is risen, granting the world great mercy.
