Watch the video above, sung by the student brothers in Ireland, of the canticle of the Passion of Our Lord. It was revealed to Catherine immediately after her first great ecstasy of the Passion. Our Lady desired Catherine to spread it as a form of prayer and contemplation for the salvation of souls.  Below is the text from the canticle which is traditionally chanted by Dominicans on Good Friday.

draw near to me and stand aloof

I am shut up and I cannot come forth

mine eye mourneth by reason of affliction

and my sweat became

like drops of blood falling down on the ground

For dogs have compassed me

the assembly of the wicked have inclosed me

I gave my back to the smiters

and my cheeks to them that plucked off the hair

I hid not my face from shame

and from those who spit on me

I am feeble and sore broken

I have roared by reason of the disquietness of my heart

The soldiers platted a crown of thorns

and put it on my head

They pierced my hands and my feet

I may tell all my bones

They gave me poison to eat

and in my thirst they gave me vinegar to drink

All they that see me laugh me to scorn

they shoot out the lip, they shake the head

They look and stare upon me

they part my garments among them, and cast lots upon my vesture

into your hands I command my spirit

redeem me, Lord, God of truth.

Remember your servant, O Lord.

when you come into your kingdom

Jesus cried with a loud voice

yielded up the ghost

The Mercy of the Lord

I will sing for ever

Surely he hath borne our griefs

and carried our sorrows

He was wounded for our transgressions

he was bruised for our iniquities

All we like sheep gave gone astray

we have turned every one to his own way

And the Lord hath laid on him

the iniquities of us all

Awake, why do you sleep, O Lord?

arise, and do not cast us off for ever

Awake, why do you sleep, O Lord?

arise, and do not cast us off for ever

Behold, God is my Savior

I will trust, and not be afraid

We ask you, come to help your servants

whom you have redeemed by your perilous blood.

V. Have mercy on us, O benign Jesus. R. Who in Thy clemency didst suffer for us.

Look down, we beseech Thee, O Lord, on this Thy family for which Our Lord Jesus Christ did not hesitate to be delivered into the hands of the wicked, and suffer the torments of the Cross.
