Whether this sacrament was instituted by Christ?

Objections

Objection 1 : It would seem that this sacrament was not instituted by Christ. For mention is made in the Gospel of the institution of those sacraments which Christ instituted, for instance the Eucharist and Baptism. But no mention is made of Extreme Unction. Therefore it was not instituted by Christ.
Objection 2 : Further, the Master says explicitly (Sent. iv, D, 23) that it was instituted by the apostles. Therefore Christ did not institute it Himself.
Objection 3 : Further, Christ showed forth the sacraments which He instituted, as in the case of the Eucharist and Baptism. But He did not bestow this sacrament on anyone. Therefore He did not institute it Himself.
