On this day the Church makes intercession for all those who suffer pains of purgatory. The souls in purgatory are helped by the suffrages of the faithful, especially by holy Mass.
Full of tears and full of dread.
Is the day that wakes the dead.
Calling all with solemn blast.
From the ashes of the past.
Lord of mercy, Jesus blest.
Grant the faithful light and rest. Amen.
— Sequence, Dies Irae, Thomas de Celano.
Have you ever been very homesick? Have you ever longed to see someone you knew you could simply never see again? Can you imagine a longing like that intensified to such a degree that death would be a relief? That is the longing of the souls in purgatory for the vision of God. Our soul has been made for God, and naturally wants to fly to Him when released from the body.
You have it in your power to satisfy that intense longing of the poor souls. Our Lord’s longing for these souls is infinitely greater than their longing for Him. Will you not do what you can so easily do to satisfy His craving and theirs incidentally? Attend Mass for that intention each day. Say the Way of the Cross whenever opportunity presents. You will not forget, will you, that your turn is coming perhaps next week, or tomorrow?
Have pity on me, have pity on me, at least you my friends, for the hand of the Lord hath smitten me. — Job
