SCRIPTURE COMMENTARY #156
And it was heard that he was in the house. And many came together, so that there was no room: no, not even at the door. And he spoke to them the word. And they came to him, bringing one sick of the palsy, who was carried by four. And when they could not offer him unto him for the multitude, they uncovered the roof where he was: and opening it, they let down the bed wherein the man sick of the palsy lay. (Mark 2:2-4)
INDULGENCES: The palsied man receives first the forgiveness of his sins, then his temporal punishment (the palsy) is removed. This is exactly what is done by indulgences, which are granted for the purpose of removing temporal punishment. Only he who is cleansed from mortal sin and is in a state of grace, can gain an indulgence.
