Whether this sacrament ought to be repeated?

Objections

Objection 1 : It would seem that this sacrament ought not to be repeated. For the anointing of a man is of greater import than the anointing of a stone. But the anointing of an altar is not repeated, unless the altar be shattered. Neither, therefore, should Extreme Unction, whereby a man is anointed, be repeated.
Objection 2 : Further, nothing comes after what is extreme. But this unction is called extreme. Therefore it should not be repeated.
