Nicene and Post-Nicene Fathers, Vol. III:
Moral Treatises of St. Augustin: Section 5

5. When therefore thou shall see any man suffer aught patiently, do not straightway praise it as patience; for this is only shown by the cause of suffering. When it is a good cause, then is it true patience: when that is not polluted by lust, then is this distinguished from falsity. But when that is placed in crime, then is this much misplaced in name. For not just as all who know are partakers of knowledge, just so are all who suffer partakers of patience: but they which rightly use the suffering, these in verity of patience are praised, these with the prize of patience are crowned.
