Whether patience is the greatest of the virtues?

Objections

Objection 1 : It seems that patience is the greatest of the virtues. For in every genus that which is perfect is the greatest. Now "patience hath a perfect work" (James 1:4). Therefore patience is the greatest of the virtues.
Objection 2 : Further, all the virtues are directed to the good of the soul. Now this seems to belong chiefly to patience; for it is written (Lk. 21:19): "In your patience you shall possess your souls." Therefore patience is the greatest of the virtues.
Objection 3 : Further, seemingly that which is the safeguard and cause of other things is greater than they are. But according to Gregory (Hom. xxxv in Evang.) "patience is the root and safeguard of all the virtues." Therefore patience is the greatest of the virtues.
