One of my favorite paschal hymns, as well as one of my favorite hymns to the Theotokos, is the “The Angel Cried” near the end of the Paschal Canon.
The Angel cried to the Lady full of grace,
Rejoice! Rejoice! O pure Virgin!
Again, I say rejoice!
Thy son is risen from His three days in the tomb!
With Himself He has raised all the dead.
Rejoice, rejoice, O ye people!
Shine! Shine! Shine, O new Jerusalem!
The glory of the Lord has shown on thee.
Exult now, exult and be glad, O Sion.
Be radiant, O pure Theotokos,
In the Resurrection, the Resurrection of thy Son.
