Whether one person is delivered from this punishment sooner than another?

Objections

Objection 1 : It would seem that one person is not delivered from this punishment sooner than another. For the more grievous the sin, and the greater the debt, the more severely is it punished in Purgatory. Now there is the same proportion between severer punishment and graver fault, as between lighter punishment and less grievous fault. Therefore one is delivered from this punishment as soon as another.
Objection 2 : Further, in point of duration unequal merits receive equal retribution both in heaven and in hell. Therefore seemingly it is the same in Purgatory.
