Hail, holy wounds of Jesus, hail,
Sweet pledges of the saving rood,
Whence flow the streams that never fail,
The purple streams of his dear blood…

In full atonement of our guilt,
Careless of self, the Saviour trod—
E’en till his heart’s best blood was spilt—
The wine-press of the wrath of God.

Come, bathe you in the healing flood,
All ye who mourn, by sin opprest;
Your only hope is Jesus’ blood,
His sacred heart your only rest…

(“Salvete Christi Vulnera“, from Divinum Officium)
