Whether the whole body should be anointed in this sacrament?

Objections

Objection 1 : It would seem that the whole body should be anointed in this sacrament. For, according to Augustine (De Trin. vi, 6), "the whole soul is in every part of the body." Now this sacrament is given chiefly in order to heal the soul. Therefore the whole body ought to be anointed.
Objection 2 : Further, the remedy should be applied to the part affected by the disease. But sometimes the disease is general, and affects the whole body, as a fever does. Therefore the whole body should be anointed.
Objection 3 : Further, in Baptism the whole body is dipped under the water. Therefore in this sacrament the whole body should be anointed.
